GENERAL GEOLOGY

Detailed explanation-1: -The lithosphere is the solid, outer part of 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-2: -The lithosphere is the rocky outer part of Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of Earth.

Detailed explanation-3: -The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere.

Detailed explanation-4: -The asthenosphere is part of a gigantic layer that takes up a full 2/3 of the Earth’s radius: the mantle. The asthenosphere is part of the upper mantle, closest to the crust. The upper mantle is made of magma and hot silicon, iron, magnesium, and oxygen.

Detailed explanation-5: -Earth’s Crust. “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.
