WebThere are three broad categories of rocks. They are Igneous, Sedimentary, and Metamorphic. Igneous Rocks Igneous rocks start as molten material that cools and solidifies. Granite, for instance was once a super heated liquid. When this liquid is beneath the surface of the earth, it’s called magma. WebGeologists use the term lithosphere to describe an outer Earth shell of rigid, brittle rock, including the crust and also the cooler, upper part of the mantle (Figure 11.15). The lithosphere ranges in thickness from 60 to 150 km (40 to 95 mi). It is thickest under the continents and thinnest under the ocean basins.

A rock is a natural substance composed of solid crystals of different minerals that have been fused together into a solid lump. Earth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. The lithosphere remains rigid for very long pe…
