Why is fresh water important?

Yet freshwater is essential for life. Plants, animals, and humans all need freshwater to survive. We use for drinking water, to irrigate crops, as part of sanitation systems, and in industrial factories, to name a few.

Why is sea water salty?

Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. When rain falls, it weathers rocks, releasing mineral salts that separate into ions.

Does Earth make new water?

Planet Earth makes its own water from scratch deep in the mantle. Our planet may be blue from the inside out. Earth's huge store of water might have originated via chemical reactions in the mantle, rather than arriving from space through collisions with ice-rich comets.
