What percentage of water in earth is in the oceans? About 97 percent of Earth's water is in the ocean The ocean covers more than 70 percent of the surface of our planet. It's hard to imagine, but about 97 percent of the Earth's water can be found in our oceans. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps. Less than one percent of all the water on Earth is fresh. A tiny fraction of water exists as water vapor in our atmosphere. According to the U.S. Geological Survey, there are over 332,519,000 cubic miles of water on the planet. A cubic mile is the volume of a cube measuring one mile on each side. Of this vast volume of water, NOAA's National Geophysical Data Center estimates that 321,003,271 cubic miles is in the ocean.

How much water is there on Earth? 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. This water is in a constant cycle -- it evaporates from the ocean, travels through the air, rains down on the land and then flows back to the ocean.

What percent of Earth is water? But how much of Earth is water — how much water contributes to the actual mass of the planet? This includes not just the surface of the Earth, but inside as well. Scientists calculate that the total mass of the oceans on Earth is 1.35 x 10 18 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.

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.

- After all, we live on land. But our world is a water world. The ocean covers 70% of Earth's surface. The average depth of the ocean is about 2.7 miles. In some places, the ocean is deeper than the tallest mountains are high! The ocean contains about 97% of all the water on Earth. The ocean plays a starring role in whatever happens with the environment.

- Distribution of the water on Earth. 1  Ocean water: 97.2 percent. 2  Glaciers and other ice: 2.15 percent. 3  Groundwater,: 0.61 percent. 4  Fresh water lakes: 0.009 percent. 5  Inland seas: 0.008 percent. 6  Soil Moisture: 0.005 percent. 7  Atmosphere: 0.001 percent. 8  Rivers: 0.0001 percent.

Water distribution on Earth Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 70% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot.

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? 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. 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). 2  Of the freshwater on Earth, much more is stored in the ground than is available in lakes and rivers.

What percent of Earth is water? In simplest terms, water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. 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.

What percentage of Earths water is: Saltwater? Freshwater? Ice? The remainder of the Earth's water constitutes the planet's fresh water resource. Typically, fresh water is defined as water with a salinity of less than 1 percent that of the oceans - i.e. below around 0.35‰.

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.

What Percent of Earth is Water? But how much of Earth is water – i.e. how much water contributes to the actual mass of the planet? 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. But in terms of mas, scientists calculate that the oceans on Earth weight about 1.35 x 10 18 metric tonnes (1.488 x 10 18 US tons), which is the equivalent of 1.35 billion trillion kg, or 2976 trillion trillion pounds.

- Oceans cover about 70 percent of the Earth's surface and about 97 percent of all water on and in the Earth is saline—there's a lot of salty water on our planet. By some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 meters) thick, about the height of a 40-story office building (NOAA).

- The background should illustrate your concepts, questions, and theory. To do this, try to ensure a tight fit between this and the proposal's other sections. Your history should be the empirical embodiment of your research problem section. This requires you to make explicit links between the story you tell and the research question, hypothesis, and theoretical approach you are using. The background should demonstrate your experience, knowledge, and passion. What you write about and how you write can reveal a great deal about your knowledge and interest in your subject. This is true in all parts of your thesis proposal, but perhaps most so in this section.

Water is never sitting still.ven though you may only notice water on the Earth's surface, there is much more freshwater stored in the ground than there is in liquid form on the surface. In fact, some of the water you see flowing in rivers comes from seepage of groundwater into river beds.

Marine life The oceans cover 71 percent of the Earth's surface and contain 97 percent of the Earth's water. Less than 1 percent of the Earth's water is fresh water, and 2-3 percent is contained in glaciers and ice caps. The oceans contain 99 percent of the living space on the planet. If the ocean's total salt content were dried, it would cover the continents to a depth of 5 feet.

Where is the salinity of the ocean when its levels are high? Is it at the equator, the north pole or at the tropic? Water & Climate: The ocean extends over 70.8% of the earth's surface. The ocean holds 98% of the 1.4 billion cubic kilometers of water on the planet, divided within three major basins.

How Much Water Is on Earth? If Earth was the size of a basketball, all of its water would fit into a ping pong ball. How much water is that? It's roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey. Some 72 percent of Earth is covered in water, but 97 percent of that is salty ocean water and not suitable for drinking. There's not a lot of water on Earth at all, said David Gallo, an oceanographer at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts.

Salinity Ocean water is about 3.5% salt. That means that if the oceans dried up completely, enough salt would be left behind to build a 180-mile-tall, one- mile-thick wall around the equator! And more than 90 percent of that salt would be sodium chloride, or ordinary table salt. The oceans sure contain a lot of salt.
