Question

mention the two layers of lithosphere medium and their characteristics​

Answer 1

The lithosphere is the outermost layer of earth, composed of rocks in the crust and upper mantle that behave as brittle solids. It is bordered by the atmosphere aloft and the asthenosphere beneath. The two layers of the lithosphere are:

• Crust - It is made up of basaltic rocks and granite. It has geographical features that are perceptible to us, such as mountain ranges, plains, etc. It also exists in the continental masses.
• Mantle - The mantle is formed by different elements such as magnesium, iron, calcium, and aluminum silicates. The mantle is divided into two parts, the upper mantle and the lower mantle, which are responsible for the tectonic plate.

Some important characteristics of lithosphere medium are:

• The elements that the lithosphere comprise are of rigid density.
• Their components are inorganically produced by the decomposition and weathering of rocks found on the surface.
• It is mainly composed of sedimentary and igneous rocks.
