A tsarin da taurari: Duniya ta core, alkyabbar, da ɓawon burodi

A abun da ke ciki na zurfin yadudduka na Duniya ya ci gaba da zama daya daga cikin mafi m tambayoyi na kimiyyar zamani, kuma duk da haka a cikin farkon karni na ashirin seismologist Beno Gutenberg kuma H. Jefferson ya ɓullo da wani tsari na ciki tsarin na duniya, bisa ga abin da Earth aka yi sama da wadannan yadudduka:

A tsakiyar karni na karshe a kan tushen da karshen a lokacin da girgizar kasa data, masana kimiyya sun zo Tsayawa akan matsayin cewa tushen daina kai hare hare da mafi hadaddun na'urar. A lokaci guda, Seismologists gano cewa, ainihin Duniya ne zuwa kashi ciki da kuma na waje, da kuma alkyabbar aka hada biyu yadudduka: saman da kasa.

Duniya ta m harsashi

The Earth ta ɓawon burodi - shi ne ba kawai saman, mafi m, amma kuma mafi kyau-karatu na duk yadudduka ta duniya surface. Its kauri (ikon) ya kai wani ganiya karkashin duwãtsu (game da 70 km) da kuma m - a karkashin duniya teku ruwa (5-10 km), da talakawan ikon ƙasa ta ɓawon burodi a karkashin filayen jeri daga 35 zuwa 40 km. A mi} a mulki daga ƙasa ta ɓawon burodi da alkyabba da aka kira da iyaka Mohorovicha ko Moho.

Ya kamata kuma a lura da cewa ɓawon burodi tare da na sama na alkyabbar samar da dutse duniya daina kai hare hare - lithosphere wanda kauri jeri daga 50 zuwa 200 km.

Wadannan da lithosphere ne astenosphere - tausasa ruwa Layer tare da high danko. Baya ga cewa, wannan musamman bangaren na duniya ta surface da aka kira da tushen volcanic aiki, tun da shi ne Aljihuna na magma zuba a cikin ɓawon burodi da kuma a kan surface.

Alkyabbar ne game da 83% daga cikin dukan girma na duniya, yana da geosphere, a kan dukkan bangarorin da suke kewaye da ciki core. A ta nuna, ne zuwa kashi biyu yadudduka: m (crystalline) da kuma m (da magma).

Deep Layer na duniyarmu

Duniya ta core ne mafi talauci da aka sani Layer na duniya. Abin dogara bayani game da shi ne kadan, tare da cikakkiyar amincewa za mu iya ce shi ne cewa da diamita ne game 7000 kilomita. An yi imani da cewa abun da ke ciki na duniya ta core ya hada da wani gami da nickel da iron.
