... Is there proof that the plates move? • Even though the crust is solid rock, it sits on top of a hot, soft, semi-solid material located in the mantle. As the material in the upper mantle moves, it drags the overlying plates across the Earth’s surface. The plates are moving about 1 centimeter to 15 c ...

... Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere. Developed from the 1950s t ...

formation of magma and igneous rocks (2)
... As magma rises toward the surface, it comes in contact with, and may incorporate, pieces of the surrounding rock. These rocks may partially or completely melt and mix into the magma, which changes its composition. This process is called assimilation. Assimilation does not occur on a large scale, bec ...
