Water is essential to life on Earth. Without it, plants and animals would not be able to survive. Around 71 per cent of Earth is covered in water in water. This includes both salt water and fresh water. Not all of Earth’s water is easily available for us to use.

The water is concentrated at the Earth’s surface, so its relative mass compared to the whole Earth is small. It amounts to about 0.02 % of Earth’s mass!

The largest drop here represents the volume of all water, the mid sized drop freshwater, and the smallest drop (near Atlanta) all of Earth’s lake water.
