Detailed explanation-1: -The most abundant rocks in the crust are igneous, which are formed by the cooling of magma. Earth’s crust is rich in igneous rocks such as granite and basalt.
Detailed explanation-2: -Oceanic Crust is the thinnest layer of earth.
Detailed explanation-3: -The lithosphere is the solid, outer part of the Earth, extending to a depth of about 100 kilometers (62 miles). The lithosphere includes both the crust and the brittle upper portion of the mantle. The lithosphere is both the coolest and the most rigid of Earth’s layers.
Detailed explanation-4: -The Earth’s Crust is like the skin of an apple. It is very thin in comparison to the other three layers. The crust is only about 3-5 miles (8 kilometers) thick under the oceans(oceanic crust) and about 25 miles (32 kilometers) thick under the continents (continental crust).
Detailed explanation-5: -Answer and Explanation: The coolest layer of the earth is the crust. The mantle is hot enough to melt rocks, and the cores are even hotter.
