Water is naturally occurring; water is found on the planet Earth.Freshwater is created by the Earth’s water cycle. Freshwater is defined as water with low concentrations of dissolved salts. Freshwater is found in rivers, streams, lakes, ponds, ice (sheets, caps and glaciers) and aquifers.
Around 70% of the planet’s surface is covered by oceans. In fact, the oceans hold about 96.5% of all water on Earth, but we can't drink it. The largest ocean on Earth is the Pacific Ocean, covering around 30% of the Earth’s surface. About 70% of the oxygen we breathe is produced by the oceans.
The water cycle is a way that water moves
all around the Earth. It never stops and doesn't really have a beginning
or an end. It's like a big circle. We'll describe it by starting with
water that's on land. For example, water that resides in the ocean or in a
lake. Some water on the surface of the ocean will
evaporate
due to heat from the sun.
When it evaporates it turns into vapor water and goes up into the
atmosphere. This vapor water gets together with a lot of other vapor water
and turns into clouds. Clouds move about the earth with the weather and
once they are so full of water they drop the water to Earth in some form
of precipitation. It could be rain, snow, sleet, or hail.
When the water hits the earth it may fall right back into the ocean
or feed a flower or be snow on the top of a mountain. Eventually this
water will evaporate and start the whole cycle again.
