Detailed explanation-1: -“Crust” describes the outermost shell of a terrestrial planet. Earth’s crust is generally divided into older, thicker continental crust and younger, denser oceanic crust . The dynamic geology of Earth’s crust is informed by plate tectonics. “Crust” describes the outermost shell of a terrestrial planet.
Detailed explanation-2: -The Earth’s crust is the Earth’s hard outer layer. It is less than 1% of Earth’s volume. The crust is made up of different types of rocks: igneous, metamorphic, and sedimentary rocks.
Detailed explanation-3: -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-4: -The Earth’s crust is its lightest, most buoyant rock layer. Continental crust covers 41percent of the Earth’s surface, though a quarter of that area is under the oceans. The continental crust is 20 to 80 kilometers thick. Its rocks hold four billion years of Earth history.
