Types of Water

Fresh Water, Brackish Water, and Salt Water


Freshwater has a very low amount of salt in it and is the only water that some plants and animals can use to live. Freshwater can be found in ponds, lakes, streams, rivers, ice caps, glaciers and wetlands. Antarctica contains 61% of the freshwater in the world.

Brackish Water

Brackish water is a mix between freshwater and saltwater. It contains about 0.5 grams to 30 grams of salt per kilogram. This usually happens when saltwater and freshwater bodies meet. Estuaries are when freshwater bodies stream into coastal waters.

All oceans contain salt water or seawater. For every kilogram of water there is 35 grams of salt. Seawater is more dense than freshwater and only some animals and plants can survive with saltwater.
