Answer 1

Explanation:

The hydrosphere is the sum of Earth's water, in the ocean, the ground, on the surface, and in the air. Approximately 71 percent of Earth's surface is covered in water. Of all of that water, only about three percent is freshwater. An even smaller amount can be used as drinking water.
