GEOLOGY

Detailed explanation-1: -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-2: -The lithosphere is the outermost layer of Earth, composed of the crust and the brittle part of the upper mantle. The term lithosphere is derived from the Greek words “lithos, ” meaning stone, and “sphaira, ” meaning globe or ball.

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 mantle’s outermost zone is relatively cool and rigid. It behaves more like the crust above it. Together, this uppermost part of the mantle layer and the crust are known as the lithosphere.

Detailed explanation-5: -The lithosphere is believed to cool with age because of the deepening of the sea-floor and the reduction in heat flow away from the mid-ocean ridges, but these trends cease and topography becomes much more erratic by about 80 Ma.
