Water is one of the most valuable resources on the Earth. About 71% of the Earth’s surface is water-covered, hence why Earth is also known as ‘Blue Planet’. The majority of fresh water is actually found underground as soil moisture and in aquifers. It will surprise you that most of the water in the Earth’s atmosphere and crust comes from saline seawater, while fresh water accounts for 1% of the total. The majority of the water on Earth is saline or salt water.
WHERE IS EARTH’S WATER?
The ocean holds 97% of the Earth’s water, the remaining is fresh water found in glaciers and ice, below the ground, in rivers, lakes and in the atmosphere. Water flows endlessly between the ocean, atmosphere and land. Earth’s water is finite, which means that the amount of water in, on and above our planet does not increase or decrease, amazing right!
According to the U.S Geological Survey if all the earths water (oceans, icecaps, and glaciers, lakes, rivers, groundwater, and water in the atmosphere) was put into a sphere, then the diameter of that water ball would be about 860 miles (about 1,385 kilometers).
The fresh water 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. There is more to our water supply than just surface water, there is also plenty water beneath our feet.
