GENERAL GEOLOGY

Detailed explanation-1: -The crust and outermost rigid mantle together make up the lithosphere. The lithosphere is divided into about 20 tectonic plates that move in different directions on Earth’s surface. The core extends down to the center of the earth, a depth of about 6400 km from the surface (Figure 6.2. 1).

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 lithosphere can be divided into two varieties: oceanic and continental. Oceanic crust is relatively thin and dense, according to Sciencing.com.

Detailed explanation-4: -In plate tectonics, Earth’s outermost layer, or lithosphere-made up of the crust and upper mantle-is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Detailed explanation-5: -The lithosphere is the rigid outermost shell of a planet or other rocky body. It is composed of two layers: the crust and the uppermost mantle.
