Water distribution on Earth Distribution of saline and fresh water[edit] The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles), with 97.5% being salt water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface.

- Activity: All the Water in the World . Did you know....? Earth is called the water planet. Between two-thirds (2/3) and three-fourths (3/4) of the earth’s surface is covered with water. The earth has different types of water: Oceans . 97.2% of total water . Ice caps/glaciers . 2.38% . Ground water . 0.397% . Surface water (e.g., lakes, rivers, streams, ponds)

Where is all of the Earth's water? Where is all of the Earth's water? The ocean holds about 97 percent of the Earth's water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.

What percent of Earth is water? Scientists calculate that the total mass of the oceans on Earth is 1.35 x 1018 metric tonnes, which is 1/4400 the total mass of the Earth. In other words, while the oceans cover 71% of the Earth's surface, they only account for 0.02% of our planet's total mass. The origin of water on the Earth's surface, as well as the fact that it has more water than any other rocky planet in the Solar System, are two of long-standing mysteries concerning our planet.

Where is all of the Earth's water? The ocean holds about 97 percent of the Earth's water; the remaining three percent is distributed in many different places, including glaciers and ice, below the ground, in rivers and lakes, and in the atmosphere. According to the U.S. Geological Survey, there are over. of water on the planet.

What Percent of Earth is Water? Illustration showing all of Earth’s water, liquid fresh water, and water in lakes and rivers. Credit: Howard Perlman, USGS/illustraion by Jack Cook, WHOI. Aside from the water that exists in ice form, there is also the staggering amount of water that exists beneath the Earth’s surface. 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 (km 3) in volume. Meanwhile, the amount of water that exists as groundwater, rivers, lakes, and streams would constitute just over 10.6 million km 3, which works out to a little over 0.7%.

Summary of the Water Cycle There is not really much fresh ware on Earth. 1.74% of all Earth's water is in this frozen form as ice caps, glaciers and snow. Only 0.75% of Earth's water is liquid water and potentially accessible as fresh water in ground water, lakes, streams and swamps. Long Answer: About 97.5% of water on Earth is salt water and 2.5% fresh water. All of the oceans are salt water and the oceans represent more than 96% of all water on Earth. Of the 2.5% fresh water, only 0.3% is in liquid form on the surface. Most of the rest is frozen or underground. Less than .01 % of all water is in lakes and rivers.

How much water is there on, in, and above the Earth? Water is on and in the Earth. The vast majority of water on the Earth's surface, over 96 percent, is saline water in the oceans. The freshwater resources, such as water falling from the skies and moving into streams, rivers, lakes, and groundwater, provide people with the water they need every day to live.

What percent of Earth is water? To break the numbers down, 96.5% of all the Earth’s water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact. 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.

Atom 1 Nearly 98% of the Earth's water is in the oceans. Freshwater makes up less than 3% of water on earth, and over two-thirds of this is tied up in polar ice caps and glaciers. Freshwater lakes and rivers make up only 0.009% of water on Earth and groundwater makes up 0.28%.  Water is essential for all life forms.

How much water is there on Earth? Water covers a vast majority of our planet. There's a whole lot of water on Earth! Something like 326,000,000,000,000,000,000 gallons (326 million trillion gallons) of the stuff (roughly 1,260,000,000,000,000,000,000 liters) can be found on our planet.

Water - The Most Important Liquid on Earth The amount of water we have on earth is always the same . However, clean water, is getting rarer because of pollution . Most of the world’s water, about 97% is in the oceans. 1.4 billion cubic kilometres is saltwater. Only 3% is the freshwater in lakes, rivers and glaciers.

- Liss. About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. But 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.

- Water is the most abundant chemical compound present on Earth's surface. About 2.1% of all of Earth's water is frozen in glaciers. If we use the analogy that 1,000 drops of water represent all of the water on Planet Earth, then we learn that: 1  972 drops are in the oceans and inland seas (97.2%)  21 drops are in glaciers (2.1%)

- People tend to think that the amount of water on the planet is unlimited, yet the amount of water on the Earth will actually stay the same. Of the water on Earth, 97.3% is oceans, inland seas, and salt lakes; the rest is fresh water (icecaps/glaciers, groundwater, freshwater lakes, atmosphere, rivers). The amount of available fresh water to humans and wildlife depends largely on how water quality is maintained.

Amount of fresh water on earth? The ocean holds 97 percent of the Earth's water; the remaining three percent is freshwater found in glaciers and ice, below the ground, or in rivers and lakes. Of the world's total water supply of about 326 million cubic miles of water, over 96 percent is saline, found in the ocean.

How much water is there on, in, and above the Earth? 1 If all of the world's water was poured on the contiguous United States, it would cover the land to a depth of about 107 miles (145 kilometers).  Of the freshwater on Earth, much more is stored in the ground than is available in lakes and rivers.

Water Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products.

Water distribution on Earth As a result, the vast bulk of the water on Earth is regarded as saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.

Water Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products.he collective mass of water found on, under, and over the surface of a planet is called the hydrosphere. Earth's approximate water volume (the total water supply of the world) is 1,338,000,000 km 3 (321,000,000 mi 3).

Water Resources Global distribution of the world’s water. The world’s water exists naturally in different forms and locations: in the air, on the surface, below the ground, and in the oceans. Freshwater accounts for only 2.5% of the Earth’s water, and most of it is frozen in glaciers and ice caps. The remaining unfrozen freshwater is mainly found as groundwater, with only a small fraction present above ground or in the air.
