What does a geologist do?

what does a geologist do and how much does he earn

Within the sciences that study our planet is geology. The person who studies and exercises on geology is known by the name of geologist. There are many people who do not know what does a geologist do.

For this reason, we are going to dedicate this article to telling you what a geologist does and what its importance is for the conservation of the planet.

what does a geologist do

To enter this world of research and knowledge of the earth, we must first understand the concept of these professionals, what a geologist is, what he does, the one in charge of studying the origin and the earth. The evolution of the Earth, considering all the natural resources it can provide.

Geological engineers represent the profession in charge of investigating, investigating, understanding and delving into everything related to the earth we inhabit, including oceans, lakes, jungles and everything that surrounds them in this study.

What is a geologist and what he does has a lot to do with the study of rocks, soils, fossils and mountains. Thanks to them, the evolution of humanity, the separation of the continents, the formation of geological structures, the composition of volcanoes and many advances in geological problems have resulted in great discoveries.

Geological engineers carry out many activities in their mission to understand the planet and develop technologies for humans without having dire effects on the planet.

What a geologist is and what he does will focus on specific objectives depending on the branch of geology in which he specializes. But even so, these experts have a responsibility to understand and act on:

  • Study the internal and external composition of the Earth.
  • Study the distribution of tectonic plates.
  • They investigate past climates.
  • They investigate the extraction of minerals.
  • Oil and gas exploration and water resources research.
  • They prevent natural disasters.

It is important to point out what a geologist is and what he does, in addition to these activities, experts in the field have identified the causes of earthquakes, ice ages, the evolution of life, and identified techniques to prevent groundwater pollution, oil extraction Many theories, such as new technologies and how to prevent landslides, have been put into practice and achieved good results.

importance of a geologist

There are many branches of geology, but all focus in one way or another on the conservation and study of the planet. Let's take a look at the most important branches to understand what a geologist is and what he does:

Geological Engineering

From geoengineering, building design and construction to applied research to maintain the environmental balance, soil conservation, prevention of deforestation, etc., to carry out projects based on avoiding natural impacts.

Environmental Geology

Solving environmental problems is part of the geologist and his job. From environmental geology, the study and control of difficulties in water, land, animals, plants, human activities and natural processes.


What is a geologist and his work in geochemistry is related to the study and composition of rocks and fluids. In addition, he analyzes the chemical processes that take place in the interior of the Earth and its outer layers.


The study of changes in the earth's surface caused by different chemical reactions, evolution and various processes is part of the activities of these professionals.


What a geologist is and his job is to study geophysics, which includes analyzing earthquakes, gravitational effects, geomagnetism, etc. What geophysicists do is look for mineral and oil deposits.


This branch studies groundwater and surface water, its behavior under natural influence, its mass and its movement.


There are specialists in the field of oceanography in the field, working on the study of the seafloor, ocean chemistry, meteorological oceanography, and climate change, as well as the study of waves and currents. Marine geologists belong to this discipline.

paleontology and fossils

Paleontologist geologists study fossils, from microbes to dinosaurs.


Studying the sediments of the Earth, how they are grouped, mixed and how they become sedimentary rocks is also part of the work of these experts.


Earthquakes, controlled sources, or explosions are studied through seismology and are extremely beneficial in predicting dangerous earthquakes, mapping the interiors of planets, and exploring for resources.

Structural geology

The study of rock deformation, plate tectonics, and fault deformation is part of the job of a structural geologist.

Unconventional energies and geologists of the future

What a geologist is and what he does also corresponds to the study of terrestrial energy, geothermal energy, wind energy and tidal energy. This is a growing field that promotes projects of great importance for the conservation of the planet.

Volcanology and Volcanoes

Studying volcanoes, their formation, location, and predicting their eruptions is one of the things geologists do as well, and he also studies the rocks produced by different types of eruptions and natural eruptions.

In general, geology seems to immerse itself in many fields of science and research, oil, coal, natural gas, geothermal, mining or mining, land use planning, metals, agriculture, these are just some of the disciplines that define what a geologist does.

The research carried out by these experts has the ability to minimize the impact or damage caused by natural disasters and the risks that can be predicted in a timely manner. There is no doubt that this is a rewarding career, and our knowledge of our beautiful planet is due to your in-depth research.

geologist and his characteristics

As for the salary of a geologist, it will depend on the knowledge and experience he has, in this sense, the income is approximately the following:

  • Geology professionals with less than 1 year of experience earn an annual salary of $48,769.
  • If your time in the job market is between 1 and 4 years, the average salary of a geologist is $53,093 per year.
  • Between 5 and 9 years of experience, you'll get an estimated $65,720 per year.
  • If the geologist is more than 10 years old but less than 20, his annual salary will be $78.820.
  • If you have more than 20 years of experience, your annual salary will be about $97.426.

I hope that with this information you can learn more about what a geologist does and what its importance is.
