Geological formations have different names depending on their morphology and their origin.  Today we are going to talk about a geographical feature of sedimentary origin known as a tombolo.  It is a geographical feature that forms a land junction between an island and land, a rock away from the mainland, between two islands, or between two large rocks.  We know some examples of tombstones such as the sandy isthmus that connects the Rock of Gibraltar with the mainland.  In this article we are going to talk about the characteristics of the tombolo and how it is formed.  General These geological formations occur because the islands produce a refraction in the movement of the waves.  Normally, this refraction of the waves is depositing the sand and the boulders in the area where they break.  As the sea level rises, it contributes to the sedimentation of all the materials deposited by the waves.  These materials that have been pushed up are making a path like the ones we see in the case of Chesil Beach.  This tombolo connects the Isle of Portland with Dorset reporting a boulder ridge along the coast.  Let's analyze the rock of Gibraltar tomb.  This rock is located in the extreme southwest of Europe on the Iberian Peninsula.  It is nothing more than a limestone promontory with a height of 426 meters.  This rock is well known for hosting around 250 macaques, the last primates in the wild in Europe.  It also has a labyrinthine network of tunnels that, together with the macaques, make it a tourist attraction all year round.  This rock is considered a natural reserve.  The tombs are also called tied islands because it seems that they have not been completely separated from the coast.  This formation may seem solitary or found in groups.  When we find it in groups, the sand sticks form an enclosure as if it were a lagoon near the coast.  These lagoons are temporary since they will surely fill with sediment over time.  How a tombolo forms This littoral drift takes place when the waves push the sediment.  This sediment can be composed of sand, silt and clay.  This sediment accumulates between the beach and the island, creating an accumulation zone that can be seen as the island is tied to the mainland.  Littoral drift depends on the direction of the wind.  In order for the wind to form continuously, the wind direction must be towards a predominant direction.  Otherwise, you will not be able to accumulate as much sediment in the same direction.  Sometimes, if these formations occur due to coastal drift, it is not considered a true tombolo.  A true tombolo is one that is formed by wave diffraction and fractional waves.  The works follow a dynamic governed by the force and direction of the wind.  These tails head towards the coast and slow down as they move through shallower waters.  This slowdown is due to the friction of the waves with the ground.  This friction force decreases the speed with which the wave travels to such an extent that they break.  Well, when it reaches the islands they are close to the coast, because the waves are moving at a slower rate than normal, they move around the island instead of over it.  As the water moves more slowly around the island, it collects sediment along the way.  The sediments are deposited and continue to accumulate until creating the sand bar that connects the island with the plan.  Obviously, this or is a very long process in time.  That is, this has to do with a geological time scale (link).  The most famous symbols in the world Next, we are going to describe the main characteristics of the most famous symbols in the world.  We started with the one in Chesil Beach.  It is located in Dorset, southern England.  It is characterized by being 115 meters high above sea level and having a beach that is 29 kilometers long and 200 meters wide.  Such is the importance of this tomboy that it has been named a World Heritage Site by UNESCO.  Another famous tombolo is that of Trafalgar.  This formation seeps into the sea and gives it a prickly pear appearance of fine sand.  It forms a beautiful landscape with extensive beaches in a rocky area offering spectacular panoramic views.  The interest in this formation is due to the fact that it is the only example in Andalusia of a double tombolo.  In this geological accident we find that the flour has been washed away by the tides and has created two tombolos that have joined with the islet and the coast.  This union has enclosed in its interior a small depression that floods when the precipitations are higher than normal.  However, this depression has its days numbered since the materials will be burying and decreasing the depth.  When the sea receded, the wind created a system of dunes on the beaches to the south of the islet.  Over time, erosion has contributed to the fossilization of these doubts.  Today this entire system of dunes is covered by plants such as junipers and mastic.  It should also be taken into account that the vegetation serves to fix the sand.  For example, we find sea wallflower, sea cargo and sea lily flowers that help to fix the sand and form a colorful mantle.  In the stabilized areas we can find sea horns, sagebrush and carnations.  On the other hand, in the floodable area, we find reeds that serve as a regular innkeeper for species of birds such as the seagull, red-billed seabird and black-footed tern.

As mentioned in some articles, the age of the Earth is thought to be between 4.400 and 5.100 billion years.  This theory is determined through the use of radiometric dating techniques thanks to the information and material that can be extracted from meteorites.  The evidence for this is consistent, so it can be said that this is the origin of the Earth.  In order to explain all the events that have occurred on our planet, actualism is used.  It is the law that is based on the conviction that the events that have occurred throughout history are the same as those that occur in the present.  In this article we are going to point out what actualism is, what its characteristics are and how important it is.  What is actualism? It is a principle issued by James Hutton and further developed by Charles Lyell (link) in which it is established that the processes that have occurred throughout the history of the Earth are similar to those that take place in the present.  Hence this theory is called actualism.  This actualism is also considered catastrophizing.  It is that today's geological characters are suddenly formed in the past thanks to transformations and evolutions.  Some of the most important tools by which actualism and uniformism serve to extract information from our past is the superposition of strata, the faunal succession and the succession of events both in the past and in the evolution of the present.  This law was confirmed in the XNUMXth century and at the beginning of the XNUMXth century.  It was naturalists who were able to verify the facts by examining the Earth's surface.  These naturalists affirmed and supported themselves on these facts in order to understand the genesis of the planet and all its evolution.  Logically it makes sense.  Why are the processes going to change over time?  The patterns of atmospheric changes, soil, geological agents (link), etc.  They are the same ones who acted at the beginning of everything.  You have to notice that before the atmosphere did not have the same composition.  But it is that, to this day, its composition is also being altered.  Perhaps it is the geological time scale (link) that makes us think that before there were other geological events than there are now.  Wind, sea currents, rainfall, storms, etc.  They also occurred when the Earth originated.  For this reason, what currentism defends is that it is these same events that have been transforming the planet and causing it to evolve, but to this day, they are still having an effect and acting.  Genesis The genesis of landforms and sediments were explained in this way by the actions of the water, the wind, and the waves that they monitored and of which they could measure the effects every day.  Those who supported catastrophism, opposed the ideas of actualism, since they defend that great valleys, geological formations and marine basins have taken place through impressive cataclysms that occurred in the past.  They can be found in religious texts such as the Bible and its Deluge that can be explained as responsible for large alluvial layers that flooded the valley floor.  Uniformity also has a place in all this.  It is a geological science whose theories say that the processes that currently exist have occurred gradually.  In addition, they are the cause of the geological characteristics that our planet has.  What uniformism defends is that these processes have been maintained until today without alterations.  Biological actualism It is a principle that sustains the relationship between the living creatures of today and those of the past.  Basically, what biological actualism does is affirm that the processes that living beings carry out today were also carried out in the past.  That none of that has changed so far.  To make it clearer and easier to understand.  If a species breathes and reproduces, it is very likely that these processes also did millions of years ago.  So, if we combine this with geological processes, we will be affirming that the same processes have always been happening and that none of that has changed today.  It is true that these processes have had their nuances, given that living beings have had to adapt to new environments and conditions that geological agents themselves have transformed over the years.  However, although the nuances are changing, the base of the process is respected, that is, it is breathed and they reproduce.  Biological actualism applies to processes such as reproduction and metabolism.  Things are already beginning to change when we talk about the behavior of living beings.  In this case, the processes are more complicated to apply biological actualism.  As individuals adapt to new conditions, we cannot guarantee that it is the same behavior that they have at all times.  Furthermore, it is impossible to deduce the behavior of extinct species and to know if it was similar to those of now, millions and millions of years ago.  For example, before an ice age (link), living beings must modify their behavior in order to adapt to the conditions and survive.  Migration is one of the behaviors that has been maintained throughout the evolution of living beings, since it is a survival instinct to want to find a habitat where they can reproduce and have good living conditions.  Geological history of actualism In order to acquire all the information about what happened throughout history, actualism and uniformitarianism are used, which are defended in the faunal succession, the succession of events and the superposition of strata.  According to the information that can be obtained from the different fossil strata, we have the following: • The position they had with respect to sea level • The temperature at which they lived • The flora and fauna present at that time • The moment when there were large tectonic movements As you can see, science tries to explain how the Earth evolved today.

Surely sometime in your life you have visited a cave.  Caves are beautiful, fascinating and unique environments on earth where we have an endemic ecosystem.  In the caves we can appreciate certain natural formations that are quite impressive for their beauty and uniqueness.  These formations are called stalactites and stalagmites.  Many people consider these geological formations as true works of art of nature.  It is something worth knowing if you have not seen it before, it will surely surprise you.  But how are stalactites and stalagmites different?  How are they formed?  We will answer all these questions throughout this article.  What are stalactites and stalagmites? Although they have similar names, there are quite remarkable differences between them.  Its formation and structure is different.  Stalactites and stalagmites have one thing in common: they are speleotomes.  This concept refers to the fact that they are mineral deposits that are formed in caves after their formation.  The speleotomes arise as a result of the chemical precipitation that arises during the formation of solid elements from a solution.  Both stalactites and stalagmites originate from calcium carbonate deposits.  These formations occur in limestone caves.  It does not mean that it is not the case where it can form in some artificial or anthropic cavities originating in other different mineral deposits.  The main difference between these two formations is the location.  Each one has a different formation process than the other and, therefore, its location within a cave also changes.  We will analyze this in more detail, describing what each one is.  Stalactites We begin with the formations that originate from the ceiling.  Its growth begins at the top of the cave and goes downward.  The start of a stalactite is a drop of mineralized water.  As the drops fall, they leave traces of the calcite behind.  Calcite is a mineral that is composed of calcium carbonate, which is why it precipitates in contact with water.  Over the years, after the fall of successive mineralized drops, more and more calcite is deposited and accumulates.  When this is crowded, we see that it gets bigger and bigger and takes on different shapes.  The most common shape is the cone shape.  The most common is to see a large number of calcite cones with water precipitating from the ceiling.  The size of the cones depends on the amount of water droplets that has been circulating in that area and the time that this flow of drops has been dragging the calcite.  It could be said that stalactites are rock formations that are created from top to bottom.  In the center of the stalactite, there is a conduit through which mineral water continues to circulate.  It is this factor that differentiates them from other geological formations that have a similar appearance.  Stalagmites We now proceed to describe the stalagmites.  On the other hand, they are formations that originate from the ground and develop upwards.  Like the previous ones, stalagmites begin to form through a mineralized drop with calcite.  These falling drops accumulate calcite deposits successively.  The formations here can vary more since they do not have a central conduit like stalactites through which water droplets circulate due to the force of gravity.  One difference is that they are more massive than stalactites.  Due to the formation process, stalagmites have a more rounded shape rather than a cone shape.  It is also more common to see some with irregular formations.  The most common shapes are those straight tubular shapes called macaroni.  Other common formations are the conulitos (they have a structure like a calcified crater), pearls (with a more rounded shape) and some more.  Stalactites and stalagmites are normally facing each other.  It is common to see a stalactite above and perpendicular to it a stalagmite.  This is due to the fact that the drops that are precipitating from the stalactite have traces of calcite that are deposited on the ground to form the stalagmite.  How stalactites and stalagmites are formed We are going to analyze the formation process of both deposits.  As we have mentioned before, they are formed by a process of chemical precipitation.  These precipitating minerals are dissolved in water.  These formations are formed because the CO2 that is dissolved in the rainwater forms calcium carbonate when it comes into contact with the limestone rock.  Depending on the rainfall regime and the level of water infiltration, these formations will occur sooner or later.  It is the rainwater that seeps through the ground and dissolves the limestone rock.  As a result, these droplets give shape to these deposits.  Calcium bicarbonate is very soluble in water and is what is formed after contact with the CO2 that rainwater brings.  This bicarbonate produces an outcrop where the CO2 escapes which, when reacting, precipitates in the form of calcium carbonate.  The calcium carbonate begins to originate certain concretions around the point where the drop falls.  This only occurs in stalactites, as the drops fall due to the force of gravity that forces them to fall to the ground.  Therefore, the drops end up spilling onto the ground.  Where to see these formations You will surely have been fascinated if you have never seen these formations before (which is not the most common).  However, we are going to tell you the places where you can find the largest stalactite and stalagmite formations.  Being a very slow formation, so that they only grow 2,5 cm in length, it takes about 4.000 or 5.000 years.  The largest stalactite in the world can be found in the Caves of Nerja, located in the province of Malaga.  It is 60 meters high and 18 meters in diameter.  It took 450.000 years to form completely.  On the other hand, the largest stalagmite in the world is 67 meters high and we can find it in the Martín Infierno cave, in Cuba.

On this planet there are areas where danger abounds more than in others and, therefore, these areas receive more striking names that you may think refers to something more dangerous.  In this case we are going to talk about the Pacific ring of fire.  Some know it as the Pacific ring of fire and others as the circum-Pacific belt.  These names all refer to an area that surrounds this ocean and where there is both a very high seismic and volcanic activity.  In this article we are going to tell you what the Pacific ring of fire is, what characteristics it has and its importance for studies and knowledge of the planet.  What is the Pacific Ring of Fire In this area shaped like a horseshoe and not a circle, large amounts of seismic and volcanic activity are recorded.  This makes this area more dangerous due to the disasters that can be caused.  This belt stretches for more than 40.000 kilometers from New Zealand to the entire west coast of South America.  It also crosses the entire area of ​​the coasts of East Asia and Alaska and passes through the northeast of North America and Central America.  As mentioned in plate tectonics (link), this belt marks the edges that exist on the Pacific plate along with other smaller tectonic plates that form what is called the earth's crust (link).  Being an area with very high seismic and volcanic activity, it is classified as dangerous.  How was it formed?  The Pacific ring of fire was formed by the movement of tectonic plates.  The plates are not fixed, but are in continuous movement.  This is due to the convection currents that exist in the Earth's mantle.  The difference in the density of materials causes them to move and lead to a movement of the tectonic plates.  In this way, a displacement of a few centimeters per year is achieved.  We do not notice it on a human scale, but it does show if we evaluate geological time (link).  Over the millions of years, the movement of these plates has triggered the formation of the Pacific ring of fire.  The tectonic plates are not totally united to each other, but there is a gap between them.  They are usually about 80 km thick and move through the aforementioned convection currents in the mantle.  As these plates move, they tend to both separate and collide with each other.  Depending on the density of each of them, one can also sink over the other.  For example, oceanic plates have a higher density than continental ones.  Therefore, they are the ones that, when both plates collide, subduct in front of the other.  This movement and collision of plates produces intense geological activity at the edges of the plates.  For this reason, these areas are considered to be particularly active.  The plate limits we find: • Convergent limits.  In these limits are where the tectonic plates collide with each other.  This can cause a heavier plate to collide with a lighter one.  In this way, what is known as a subduction zone is created.  One plate subducts over the other.  In these areas where this occurs, there is a large volcanic quantity because this subduction causes the magma to rise through the crust.  Obviously, this does not happen in a moment.  It is a process that takes billions of years.  This is how the volcanic arches have been formed.  • Divergent limits.  They are totally opposed to the convergent ones.  In these the plates are in a state of separation.  Each year they separate a little more, creating a new ocean surface.  • Transformation limits.  In these limits the plates neither separate nor come together, they only slide in a parallel or horizontal way.  • Hot spots.  They are the regions where the terrestrial mantle that is located just below the plate has more temperature than other areas.  In these cases, the hot magma is able to rise to the surface and produce more active volcanoes.  The limits of the plates are considered those areas where both geological and volcanic activity are concentrated.  For this reason, it is normal that so many volcanoes and earthquakes are concentrated in the Pacific ring of fire.  The problem is when an earthquake occurs in the sea and results in a tsunami with the corresponding tsunami.  In these cases, the danger increases to such an extent that it can cause disasters like the one in Fukushima in 2011.  Pacific Ring of Fire Activity As you may have noticed, volcanoes are not evenly distributed throughout the planet.  Quite the contrary.  They are part of an area where geological activity is greater.  If this activity did not exist, volcanoes would not exist.  Earthquakes are caused by the accumulation and release of energy between plates.  These earthquakes are more common in countries where we have located along the Pacific Ring of Fire area.  And it is that this ring of fire concentrates 75% of all the volcanoes that are active on the entire planet.  90% of earthquakes also occur.  There are numerous islands and archipelagos together and different volcanoes that have violent and explosive eruptions.  Volcanic arches are also common.  They are chains of volcanoes that lie on top of subduction plates.  This fact makes many people around the world have both fascination and fear for this belt of fire.  This is because the force with which they act is tremendous and can unleash real natural disasters.
