Lithosphere and Its Importance

The Earth is the only planet which has life. Human beings can live here because the life sustaining elements of land, water and air are present on the earth.

Lithosphere:

The solid portion of the earth is called the lithosphere. It comprises the rocks of the earth’s crust and the thin layers of soil that contain nutrient elements which sustain organism. There are two main divisions of the earth’s surface. The large landmasses are known as the continents and the huge water bodies are called the ocean basins. Elevation of land is measured from the level of the sea, which is taken as zero. The highest mountain peak Mt. Everest is 8,848 meters above the level. The greatest depth of 11,022 meters is recorded at Mariana Trench in the Pacific Ocean.
