The optimum depth for their formation is about 120 miles beneath the surface , in the molten mantle . 其形成的最佳深度是在地表之下约120英里,在熔化的地幔曾。 Rock formed from molten matter is known as igneous , and geologists classify igneous rock by its texture . 由熔化的物质凝固形成的岩石...
Deep below the Earth's crust, molten rock rises and falls, driving the movement of tectonic plates on our planet's surface — and for some time, researchers have debated whether the moon also has a molten layer of rock sandwiched between its core and solid exterior. New evidence, based ...

1. When an asteroid hits Earth, when it slams into Earth's crust, we think that causes molten rock from deep below the surface to rise up into the impact area. (Official35-L4) 当小行星撞击地球时,它撞入地球的外壳,我们认为它会导致地球内部的熔化的岩石上升冲入陨石坑区域。 2. And we said...
Molten rock beneath the Earth's crust is called: A. magma B. liquicite C. lava D. igneous Earth's Crust: There are four major layers (components) that the structure of the earth is divided into. From the surface to the core, the layers are the crust, ...

According to the research, which Hua began as a graduate student at Brown University, the convection of heat and rock in the mantle are the prevailing influence on the motion of the plates. Although the Earth’s interior is largely solid, over long periods of time, rocks can shift and flo...
