Are waterfalls freshwater or saltwater?

You see, rain falls on the land as fresh water. As this water flows downward, it ever so slightly erodes the rocks and soil. This causes an ever so slight amount of salt and minerals to dissolve in the water and continue downstream. Eventually, all the dissolved minerals get dumped into the ocean.

What are the importance of rivers?

How can waterfalls be used as a potential source of hydroelectric power?

Hydroelectricity is the generation of electricity using the kinetic energy of water. In the case of a waterfall, gravitational potential energy of water first changes into the kinetic energy of water. This kinetic energy is partially converted into electrical energy by a generator.

Why do we need to protect waterfalls?

As they flow into the different rivers, waterfalls purify the water. Purification of water helps the different aqua life to live through provision of oxygen. … Waterfalls also help in turning waste that runs in the water into nutrients which help plants to grow.
