What Is the Land to Water Ratio on Earth? The land-to-water ratio on Earth is about 29 percent land to 71 percent water, according to the U.S. Geological Survey. Most of the Earth's water, about 96.5 percent, is saline water contained in the oceans. Continue Reading.

Water The 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 km3 (321,000,000 mi3). Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle. The majority of water on Earth is sea water.

How Much of the Earth is Covered with Water? About 70% of the earth’s surface is covered with water. Ninety-seven percent of the water on the earth is salt water. Salt water is filled with salt and other minerals, and humans cannot drink this water. Although the salt can be removed, it is a difficult and expensive process. Two percent of the water on earth is glacier ice at the North and South Poles.

Interior Walls The key to the open concept is in the use of truss framing. Trusses allow your builder to eliminate load bearing walls. It's made of floor trusses and roof trusses joined by studs, which allow the interior to be free of load bearing walls or posts. A truss frame is often used to span a longer area than a rafter or floor joist can span, thereby enabling an interior space to be free of walls requiring load bearing.

What Percent of Earth is Water? This includes not just the surface of the Earth, but inside as well. 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.

Land Land mass refers to the total surface area of the land of a geographical region or country (which may include discontinuous pieces of land such as islands). It is written as two words to distinguish it from the usage landmass, the contiguous area of land surrounded by ocean. The Earth's total land mass is 148,939,063.133 km2 (57,505,693.767 sq mi) which is about 29.2% of its total surface. Water covers approximately 70.8% of the Earth's surface, mostly in the form of oceans and ice formations.

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. 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 332,519,000 cubic miles 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 (km3) in volume.

Water, Water, Everywhere Water is everywhere on Earth. About seventy percent of the surface of the Earth is covered by water. If you were an alien visiting the planet, you would see a giant blue sphere from space (especially on the Pacific Ocean side). Not only is water everywhere, but all life depends on water. The tiniest bacteria and the largest dinosaurs have all needed water. The hydrosphere is the world of water that surrounds all of us. Because water is so important, it makes up an entire section of the earth sciences.

- 1 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.

Water distribution on Earth What is the percentage of the Earths water is salt water? The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles). About 97.5% of water on Earth is salt water and 2.5% fresh water. Of the 2….5% fresh water, only 0.3% is in liquid form on the surface. A breakdown of the various forms of water is as follows, going from the largest to the smallest.

How much water is there on, in, and above the Earth? The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. 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 never sitting still.

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.

- 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%) 2  21 drops are in glaciers (2.1%)  6 drops are in ground water and soil moisture (0.6%)

Peripheral Neuropathy Treatments Peripheral Neuropathy Treatments. Neuropathy is a disease that affects our nerves. Peripheral neuropathy is a condition where there is damage to the peripheral nervous system, the vast communications network that transmits information from the brain and spinal cord (the central nervous system) to every other part of the body. Discomfort in the extremities is usually the first sign noticed by sufferers.
