What can you say about the earth's sphere?

Answer 1

The Earth contains four spheres: hydrosphere, atmosphere, geosphere, and biosphere . The hydrosphere is a dynamic mass of water that is continually on the move. It represents water that is at or near Earth's surface. The hydrosphere comprises 71 percent of Earth's surface and 97 percent of Earth's water. Freshwater, underground water, streams, lakes, ice, and glaciers are included in the hydrosphere. The atmosphere is the Earth's gaseous envelope. It is thin and tenuous and it protects us from the sun's heat and ultraviolent radiation. The largest of the four spheres is the geosphere, which is solid Earth, the interior and solid surface. It lies beneath the atmosphere and the oceans, and it extends from the surface to the center of our planet. The biosphere is the totality of all plant and animal life, and it has a strong influence on the other spheres due to its constant interaction with them.
