Answers
The Lithosphere
The lithosphere, sometimes called the geosphere, refers to all of the rocks of the earth. It includes the planet's mantle and crust, the two outermost layers. The boulders of Mount Everest, the sands of Miami Beach, and the lava erupting from Hawaii's Mount Kilauea are all components of the lithosphere.
The actual thickness of the lithosphere varies considerably and can range from roughly 40 km to 280 km.1 The lithosphere ends at the point when the minerals in the earth's crust begin to demonstrate viscous and fluid behaviors. The exact depth at which this happens depends on the chemical composition of the earth as well as the heat and pressure acting upon the material.
Explanation:
The Hydrosphere
The hydrosphere is composed of all of the water on or near the planet's surface. This includes oceans, rivers, and lakes, as well as underground aquifers and the moisture in the atmosphere
The Biosphere
The biosphere is composed of all living organisms: plants, animals and one-celled organisms alike. Most of the planet's terrestrial life is found in a zone that stretches from 3 meters below ground to 30 meters above it. In the oceans and seas, most aquatic life inhabits a zone that stretches from the surface to about 200 meters below.5
