we use about 1/4 of earth's water
Less than 1% of Earth's water is fresh water that is suitable for drinking and use. The majority of this fresh water is found in glaciers and ice caps, with the remaining amount found in lakes, rivers, and underground aquifers.
Approximately 97% of the Earth's surface is covered by salt water.
Approximately 0.3% of the earth's hydrosphere is available for human use as freshwater. The rest is saltwater found in oceans and seas.
Approximately 2.5% of Earth's water is fresh water, of which only about 0.5% is readily accessible for use by living organisms. The majority of fresh water is stored in glaciers, ice caps, and deep underground aquifers.
Most is salty sea water. Well acually most of earths water is ocean water (which is sea water and very salty) but if we pay for pumping system to take the salt out it will cost alot of money so that is one answer but another is that half of earths water is locked away in big glaciers we cant get to......
You can at least use 1/4 of the water on Earth, but at most, 3/4 of it.
Yes water cycle use up earths supply. Water is evaporated from earth's surface.
70% or 80% of water covers the earths surface
three percent of all the earths water is fresh water
about 30%
3% of the earths water, is fresh water
3% is fresh, but 1% is for drinking.
3%
because
Roughly 75% of Earths Surface is covered by water. (including the Oceans, lakes and land Ice).
Water 75%
