But yet all the fresh water is not available to us. In simplest terms, water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. What percent of the earth's water is freshwater? Most water in Earth's atmosphere and crust comes from the World Ocean's saline seawater, while fresh water accounts for nearly 1% of the total. There is no shortage of water on earth. https://www.youtube.com/channel/UC0-KklSGlCiJDwOPdR2EUcg/, Astronomy Cast: Like us on Facebook: https://www.facebook.com/universetoday Episode 363: Where Did Earth’s Water Come From?

But in terms of mas, scientists calculate that the oceans on Earth weight about 1.35 x 1018 metric tonnes (1.488 x 1018 US tons), which is the equivalent of 1.35 billion trillion kg, or 2976 trillion trillion pounds. In icecaps, icebergs, we can see the fresh waters. No! The earth boasts of some of the largest water bodies including the oceans, lakes, and rivers that stretch across approximately two-thirds of its surface. In the earth when the water takes the seventy-one percentage, the salty water already takes 96.5%. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.

In simplest terms, water makes up about 71% of the Earth's surface, while the other 29% consists of continents and islands. The density of the water depends upon the salinity of the water as the density of the water increase with the increase of the salinity. Percentage Of Water On Earth. In terms of volume, all of the water on Earth works out to about 1.386 billion cubic kilometers (km³) or 332.5 million cubic miles (mi³) of space. of the water. The quantity of the freshwater is very low on the earth as the big part ocean carries the saltwater. Not that long ago, it was believed that our planet formed dry some 4.6 billion years ago, with high-energy impacts creating a molten surface on the infant Earth.

Seen in this context, the limited and precious nature of freshwater becomes truly clear. This conclusion was reached by examining meteorites thought to have formed at different times in the history of the Solar System. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. However, more recent research conducted by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts, has pushed the date of these origins back further. The freshwater groundwater takes about 30.1% and ice caps, glaciers take 68.7%.

This is just 1/4400 the total mass of the Earth, which means that while the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass. 3% is freshwater. https://www.amazon.com/Universe-Today-Ultimate-Viewing-Cosmos/dp/1624145442/, Audio Podcast version: For mining processes ( 5%)and industrial training (53%), people use the saltwater. Most water in Earth's atmosphere and crust comes from the World Ocean's saline seawater, while fresh water accounts for nearly 1% of the total. These meteorites are dated to the same epoch in which water was believed to have formed on Earth – some 11 million years after the formation of the Solar System. The oceans hold 96.5 percent of that water, and there is also water in icecaps and glaciers. Wallace Arthur is an evolutionary biologist and emeritus professor of Zoology at the National University of Ireland, Galway. Less than one percent of all the water on Earth is fresh. If you could melt all that ice, and the Earth’s surface was perfectly smooth, the sea levels would rise to an altitude of 2.7 km.
