What is a foliated rock? What's the hottest thing on Earth? What are rock strata? What are the commonly occurring carbonate minerals in an ocean? Where is the youngest rock in the Earth's crust found? What is molten rock called?
The primitive Earth was a mass of molten rock. What was the main factor that made it molten? A. Radioactive decay B. Gravitational compression C. Impact heating D. All of the above 相关知识点: 试题来源: 解析 D。解析:原始地球是一团熔融的岩石。A选项放射性衰变会释放出热量,这有助于地球...
Often, this molten rock forms in areas where ocean water 通常,在形成这些熔融岩石的区域, is able to slip into the Earth’s mantle and lower the layer’s melting point. 海水能渗入地幔,降低地幔的熔点。 The resulting magma typically remains under the Earth’s surface 由于三个地质因素之间的微妙...
It is simply power derived from the Earth’s internal heat. This thermal energy is contained in the rock and fluids beneath Earth’s crust. It can be found from shallow ground to several miles below the surface, and even farther down to the extremely hot molten rock called magma(岩浆). ...
Yellowstone sits above a spot in the Earth's mantle where columns of hot, molten rock called plumes rise to form volcanoes in the planet's crust. This spot is called a hotspot, and it creates atype of volcano not associated with a plate boundary. Yellowstone has produced three calderatypes...

A volcanic pipe is the channel bored through the earth's crust that allows molten material from amagmachamber deep below the surface to travel up and out during a volcanic eruption. The entryway for magma into the pipe is called a vent, which ends in the depression called acrater. Lava,...
well, one of the most interesting features on the surface are, in fact, the shield volcanoes.Shield volcanoes form when magma comes out of the ground in the same spot over and over again.Remember, magma is hot, molten rock that's underground and it's called lava when it reaches the sur...
Magma is molten rock and can be found below the Earth's surface and above the Earth's surface. When above, it is called lava. Magma can cool when it's both inside the Earth and outside the Earth. Answer and Explanation:1 When magma cools, it creates igneous rock. Igneous is a word...
aWhen a volcano erupts,the molten rock that flows frow it is called lava.Then lava may run for some distance,or it may pile up near the volcano,making the mountain larger. 一座火山爆发时,淹没它称为的 frow 的熔铸的岩石 lava.Then 熔岩可能争取一些距离,或它可能在火山附近搁浅,使山变得更大。
