Thaum nws solidifies, nws tsim a loj, tiaj tus ntawm pob zeb tsis pom kev. Qee lub toj siab loj, zoo li Columbia Plateau hauv Washington, Oregon, thiab Idaho uas npog tshaj 161,000 square kilometers (63,000 square mais).
Thaum magma solidifies nws tsim dab tsi?
Molten material in the Earth is called magma. Hauv cov ntsiab lus yooj yim magma tuaj yeem xav tias yog pob zeb molten. Thaum magma txias, nws solidifies tsim pob zeb uas yog hu ua " igneous pob zeb ".
Yuav ua li cas magma hu ua?
Magma uas tau txias rau hauv cov khoom yog hu ua igneous pob. Magma yog kub heev-nruab nrab ntawm 700 ° thiab 1, 300 ° C (1, 292 ° thiab 2, 372 ° Fahrenheit).
Yuav ua li cas pob zeb tsim thaum lub pob zeb melts txias thiab solidifies?
Igneous pob zeb (los ntawm lo lus Latin rau hluav taws) yog tsim thaum cov khoom kub molten txias thiab solidifies. Igneous pob zeb kuj tuaj yeem ua ob peb txoj kev sib txawv. Thaum lawv tsim nyob rau hauv lub ntiaj teb, lawv hu ua intrusive, los yog plutonic, igneous pob zeb.
Yuav ua li cas tom qab magma tsim?
Magma txias thiab crystallizes los ua pob zeb tsis pom kev. Igneous rock undergoes weathering (los yog breakdown) tsim sediment… Raws li cov pob zeb sedimentary yog faus nyob rau hauv ntau thiab ntau cov sediment, qhov kub thiab siab ntawm faus ua rau metamorphism tshwm sim. Qhov no hloov cov pob zeb sedimentary rau hauv cov pob zeb metamorphic.
