Pehea e ʻike ai inā he meteorite

pehea e ʻike ai inā he meteorite ka mea āu i ʻike ai

ʻO Meteorite kēlā mau pōhaku nui i hiki ke komo i ka lewa o ka honua a hāʻule i ka ʻili o ka honua. Eia naʻe, ke ʻike mākou i kahi pōhaku nui me kekahi mau ʻano, paʻakikī pehea e ʻike ai inā he meteorite a i ʻole he pōhaku.

No kēia kumu, e hoʻolaʻa mākou i kēia ʻatikala e haʻi iā ʻoe pehea e ʻike ai inā he meteorite ka mea āu i ʻike ai a ʻaʻole paha a me kona ʻano a me kona kumu.

Pehea e ʻike ai inā he meteorite

ponferrada meteorite

E hāʻule mau ana nā ʻāpana meteorites ma ko kākou honua mai waho mai. Hāʻule lākou i loko o ke kai a i ʻole nā ​​​​wahi i hoʻohana ʻole ʻia, no laila ʻaʻole hiki ke loaʻa kahi ʻāpana o ka asteroid ma kahi. Inā ʻike ʻoe i kahi pōhaku ma ke kula āu e makemake ai, hiki iā ʻoe ke hoʻohana i kēia mau hana hoʻopunipuni e ʻike inā he mea mai kēia ao.

Hoʻokomo ka magnet i kahi meteorite ferromagnetic. Inā kokoke ia i ka magnet a ʻaʻole pili, ʻaʻole paha ia he meteor ferromagnetic. ʻO nā meteorites wale nō e pili ana i kahi magnet i manaʻo ʻia he ferromagnetic.

ʻO Regmaglypts kahi hoʻoheheʻe ma ka ʻili o nā pōhaku ʻeleʻele a ʻeleʻele paha. ʻOi aku ka ʻeleʻele o nā pōhaku ʻeleʻele a pau ma mua o nā pōhaku maʻamau a loaʻa nā ʻili ma ko lākou ʻili. ʻO ke kaumaha kekahi mea maʻamau. Ua kaumaha loa lakou, ke kaumaha ma ma waena o 4 a me 8 grams no ke kenimika cubic.

Inā ʻaʻole maopopo ʻoe, hiki iā ʻoe ke hoʻomaloʻo i ka pōhaku me ka pepa ʻili wai a i ʻole ka paʻi. Meteorite maʻamau e like me ke metala ke hoʻopololei ʻia. Ke ʻike ʻia kahi asteroid, pono e hele i kahi keʻena geology no ka nānā ʻana. Hoʻoholo nā hoʻokolohua inā ʻo ka asteroid ka mea i manaʻo ʻia (he koena o ka asteroid i hāʻule). Inā hala ka asteroid i nā hoʻokolohua 9 i luna, e manaʻo ʻia he ʻoiaʻiʻo.

Aia ma waena o Mars a me Jupiter kahi ākea kahi i manaʻoʻiʻo ai kekahi ua luku ʻia ka honua i ka hoʻokumu ʻana o ka ʻōnaehana solar. Ua manaʻo ʻia nā miliona o nā pōhaku liʻiliʻi a me nā pōhaku i hoʻokumu i ke kāʻei asteroid, ma hope o ka mea i manaʻo ʻia he mau miliona mau ʻāpana ʻōpala. I kekahi manawa, hāʻule kekahi o kēia mau ʻāpana o ka asteroid i waho o ka orbit a kū i ka Honua.

Nā mea e aʻo ai pehea e ʻike ai inā he meteorite

nā ʻano o asteroids

ʻO nā mea ʻeleʻele a puni ka meteorite, inā ʻaʻole ia i haki i ka hopena, ʻo ia ka mea e hoʻokaʻawale ai ka meteorite mai nā ʻāpana ʻē aʻe i loaʻa iā mākou. ʻOi aku ka mānoanoa o ka ʻōpala o nā meteorites pōhaku ma mua o nā meteorites metala, ʻaʻole ʻoi aku ma mua o 1 mm mānoanoa.

ʻO nā pūpū o nā meteorites pōhaku he silica amorphous (he ʻano aniani) i hui pū ʻia me ka magnetite, ka mea i loaʻa mai nā silicates a me ka hao i hana i ka nui o nā meteorites pōhaku.

ʻO ka papa waho o nā meteorites metala i haku ʻia me ka hao ʻokikene i kapa ʻia he magnetite, ʻo ia ka submillimeter maʻamau. Hoʻopilikia pinepine ʻia lākou e nā ʻano ʻokoʻa o ka lewa, a inā e waiho ʻia lākou e noho ma ka honua no ka manawa lōʻihi me ka ʻike ʻole ʻia, e hele lākou i kahi hiʻohiʻona ʻeleʻele.

ʻO ka haʻihaʻi a me ke kuhikuhi ʻana

ʻO ia nā hale a mākou e ʻike ai i loko o ka ʻāʻī o kekahi mau meteorites pōhaku e ʻike ʻia ai ua māhā. Hoʻokumu ʻia lākou ma muli o ka hoʻomaloʻo wikiwiki ʻana o ka ʻōpala o ka honua, e hoʻomaka ana mai ka wela kiʻekiʻe loa i hana ʻia e ka friction a hiki i ka wela o ka lewa, i kekahi manawa ma lalo o ka hau. He mea koʻikoʻi kēia mau māwae i ka hoʻoilo ʻana o nā meteorites.

Hiki i nā meteorite ma ka lewa ke hoʻololi a hoʻomau i ka neʻe laina, a i ko lākou hele ʻana i ka lewa, hiki iā lākou ke loli koke a noho i ka neʻe a hiki i ka honua. Pēlā e ʻokoʻa ai kou helehelena.

ʻAʻole makemake ʻia nā meteorite e wili i ka wā hāʻule a no laila ʻaʻole maʻamau. E loaʻa i nā meteorites ʻaʻole i hoʻololi ʻia kahi ʻano paʻa i ka wā hāʻule, e hana ana i cone me nā laina erosion makemake.

meteorites angular

Hōʻike nā ʻili o nā meteorites pōhaku i kēia mau ʻano angular, ma waena o 80-90º, me nā poʻe poʻe a me nā ʻaoʻao. Hāʻawi pinepine ʻia lākou e nā polylines.

Regmaglyphs: he mau notches i hana ʻia ma ka ʻili ma ke ʻano spherical, conical i ko lākou hāʻule ʻana ma muli o ke ʻano o ka lewa. ʻO nā meteorite metala ka mea maʻamau.

Nā laina lele: I ka wā hāʻule, wela ka ʻili o ka meteorite a hiki i ka wela loa, e hoʻoheheʻe ai ka mea a me ke ʻano he wai. I ka wā o ka hū ʻana o ka meteorite, inā paʻi ia, ua kū koke ka hana mehana a me ka hoʻoheheʻe ʻana. Hoʻomaʻalili nā kulu ma luna o ka ʻōpala, hana i nā laina lele. Ma waho aʻe o kāna haku mele ʻana, ua hoʻoholo nui ʻia kona ʻano e kona orientation a me ka rotation.

kala a me ka pauda

Ke ʻano hou nā meteorites, ʻeleʻele lākou, a hiki i kā lākou hui hui ke hōʻike i nā kahawai a me nā kikoʻī e kōkua i ka ʻike ʻana iā lākou. Ma hope o ka moe ʻana i ka lepo no ka manawa lōʻihi, hoʻololi ka meteor i ka waihoʻoluʻu, pau ka ʻōpala fusion, a nalowale nā ​​kikoʻī. ʻO ka hao i loko o nā meteorites, e like me ka hao i nā mea hana, hiki ke hoʻoheheʻe ʻia e ka wā.. Ke hoʻoheheʻe ʻia ka metala ferrous, hoʻohaumia ia i ka matrix o loko a me ka ʻili waho o ka pōhaku. E hoʻomaka me ka ʻulaʻula a i ʻole ka ʻalani i loko o ka ʻōpala ʻeleʻele hehee. I ka wā lōʻihi, e lilo ka pōhaku i ʻeleʻele ʻeleʻele. ʻIke ʻia ka ʻōpala hui, akā ʻaʻole ʻeleʻele hou.

Inā mākou e lawe i kahi ʻāpana a hamo i ke kua o ka tile, ʻo ka lepo i hoʻokuʻu ʻia e hāʻawi iā mākou i kahi ʻike: inā ʻeleʻele, manaʻo mākou he meteorite, akā inā ʻulaʻula, pili mākou i ka hematite. Inā ʻeleʻele, ʻo ia ka magnetite.

Nā hiʻohiʻona maʻamau ʻē aʻe

pehea e ʻike ai inā he meteorite

ʻOiai e noʻonoʻo ana i kēia mau hiʻohiʻona e hoʻokaʻawale iā lākou mai nā pōhaku ʻē aʻe a puni, loaʻa nā meteorites i nā ʻano ʻē aʻe e pono e noʻonoʻo ʻia:

  • ʻAʻohe quartz ka meteorite
  • ʻAʻohe kala ikaika a ʻālohilohi paha nā meteorite, ʻeleʻele a ʻeleʻele paha lākou no ka mea ua hoʻololi ʻia e ka oxygen.
  • He keʻokeʻo maʻamau nā kaha i ʻike ʻia ma kekahi mau meteorites a ʻaʻohe kala.
  • ʻAʻohe ea a me nā lua i loko o nā meteorites, ʻo 95% o nā meteorites ka mea maʻamau.
  • ʻO nā meteorite metala a me nā meteori metala ua hoihoi nui ʻia i nā magnet.

Manaʻo wau me kēia ʻike hiki iā ʻoe ke aʻo hou e pili ana i ka ʻike inā he meteorite ka mea āu i ʻike ai a ʻaʻole paha.


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
