How does water get back to the Earth?
The answer is that water is constantly recycled through the Earth’s system through a process called the water cycle. This evaporated water accumulates as water vapour in clouds and returns to the Earth as rain or snow. The returning water falls directly back into the oceans, or onto land as snow or rain.
How does fresh water stay fresh?
Meanwhile water on the ocean’s surface evaporates into the air, ditching all those salts and minerals. It then falls back on land as fresh water, replenishes the lakes and rivers, and the cycle continues. In lakes and rivers, theres enough turnover that the water stays fresh.
How is Earth’s supply of fresh water continuously renewed?
The hydrologic cycle constantly renews Earth’s supply of freshwater. The sun provides energy to drive the system as it heats Earth, causing evaporation of liquid water. Water evaporates from the surface of all the bodies of water on Earth. The water vapor rises with the less dense warm air.
