GEOLOGY

Detailed explanation-1: -The vast majority of water on the Earth’s surface, over 96 percent, is saline water in the oceans. The freshwater resources, such as water falling from the skies and moving into streams, rivers, lakes, and groundwater, provide people with the water they need every day to live.

Detailed explanation-2: -The oceans are, by far, the largest storehouse of water on earth-over 96% of all of Earth’s water exists in the oceans.

Detailed explanation-3: -Of all the water that exists on our planet, roughly 97% is saltwater and less than 3% is freshwater. Most of Earth’s freshwater is frozen in glaciers, ice caps, or is deep underground in aquifers.

Detailed explanation-4: -The rain physically erodes the rock and the acids chemically break down the rocks and carries salts and minerals along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers and then to the ocean.
