Energy Types | Renewable Hydropower Nuclear & More How It Works? Approximately what percent of Earth's total water supply is located in the oceans? Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. 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. 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 this again lakes contain 20.9% and ground ice and permafrost contain 69%. In this again lakes contain 20.9% and ground ice and permafrost contain 69%.Fresh Water. Farmers use toxic chemicals to kill the kits but in the raining time the harmful toxins flow with the water and mix up in the pond or river. While water itself is not blue, water gives off blue light upon reflection. According to this new study, the world’s oceans also date back 4.6 billion years, when all the worlds of the inner Solar System were still forming. 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.

In this again lakes contain 20.9% and ground ice and permafrost contain 69%. 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. If you were to gather all the Earth’s fresh water together as a single mass (as shown in the image above) it is estimated that it would measure some 1,386 million cubic kilometers (km3) in volume. This includes not just the surface of the Earth, but inside as well. That leaves us with 0.4% of the earth’s water, in the form of rivers and underground aquifers, to try to utilize for our consumption and societal development. People use this saltwater mainly in thermoelectric power plants. We’ve also recorded an episode of Astronomy Cast all about planet Earth. Meanwhile, the amount of water that exists as groundwater, rivers, lakes, and streams would constitute just over 10.6 million km3, which works out to a little over 0.7%. 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. And More…, Episode 698: Open Space 95: Would SpaceX Have Survived without NASA?

However, despite the fact that three-quarters of the Earth are made up of water, less than 3% of the water is fresh, non-saline water. Instagram – https://instagram.com/universetoday, Team: Fraser Cain – @fcain / [email protected] 3% is freshwater. When less than 500 ppm or parts per million of dissolved salts like calcium ions, magnesium ions are present in the water, we can call this type of water is freshwater.
