Earth crust geology
WebCrust is very thin relative to Earth’s radius. Lithosphere. The lithosphere is composed of both the crust and the portion of the upper mantle. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is about 100 kilometers thick. WebThe crust of Earth is of two distinct types: Oceanic: 5 km (3 mi) to 10 km (6 mi) thick [4] and composed primarily of denser, more mafic rocks, such as basalt, diabase, and gabbro. Continental: 30 km (20 mi) to 50 km (30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite.

WebThe earth's surface, seemingly solid, is actually broken up into many huge plates, all floating on top of the Earth's molten interior. As these plates slowly drift, the continents and adjacent sea floor either move apart or push into one another. Continental crust is thicker than oceanic crust and tends to be less yielding.
