GEOLOGY

Detailed explanation-1: -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-2: -The plates move on a hot flowing mantle layer called the asthenosphere, which is several hundred kilometers thick. Heat within the asthenosphere creates convection currents (similar to the currents that can be seen in the lava lamp).

Detailed explanation-3: -Lithospheric plates (continental and oceanic) above the asthenosphere.

Detailed explanation-4: -The lithosphere is above the asthenosphere and actually contains the crust and a small part of the asthenosphere as well. The lithosphere is rigid and the tectonic plates are located there.

Detailed explanation-5: -The asthenosphere is the part of the mantle that flows and moves the plates of the Earth. The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock.
