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 ocean.
About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all 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.
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.
Over 97 percent of the earth's water is found in the oceans as salt water. Two percent of the earth's water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth's water available to us for our daily water supply needs.
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
The ocean covers more than 70 percent of the surface of our planet.
Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75% of the Earth's surface. Geologic evidence suggests that large amounts of water have likely flowed on Earth for the past 3.8 billion years—most of its existence.
-According to a current study from the U.S. Geological Survey, the Earth has its 71 percent covered in water. Out of that, 97 percent is salty ocean water and not fit for drinking. -In terms of weight, only 0.5% of Earth's weight is water.
Whereas, according to the new study, water once covered at least close to 100% of Earth's surface, now it covers only 71%. There was also a previous study from last year that indicated that 3.2 billion years ago, Earth had much less surface land than it does now.
Water covers 71 percent of Earth's surface. And almost all of it—96.5 percent—is salt water. Salt water has different kinds of salt in it, but it mostly has sodium chloride, the same salt we add to our food. Just 3.5 percent of the water on Earth is fresh water we can drink.
Scientists have found evidence that Earth was covered by a global ocean that turned the planet into a “water world” more than 3bn years ago. Telltale chemical signatures were spotted in an ancient chunk of ocean crust which point to a planet once devoid of continents, the largest landmasses on Earth.
Our freshwater is locked up in the Antarctic Ice Sheet. About 71% of the Earth is covered in water.
The Antarctic ice sheet holds about 90 percent of the fresh water that exists on the Earth's surface. The ice sheet covers approximately 8.7 million square miles. The Greenland ice sheet also contains large volumes of fresh water.
So while Europa is only one-fourth the diameter of Earth, its ocean may contain twice as much water as all of Earth's oceans combined. Europa's vast and unfathomably deep ocean is widely considered the most promising place to look for life beyond Earth.
More than 80 percent of the Earth's surface--above and below sea level--is of volcanic origin. Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth's earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life.
The Mantle
This layer is by far the thickest layer of Earth, about 1,800 miles thick! It also makes up about 85% of Earth's volume.
Air is mostly gas
The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Covering 72 percent of the Earth and supplying half its oxygen, the ocean is our planet's life support system.
The surface of our planet Earth is more than two thirds (72 percent) covered by water. We call small stretches of water "seas" and larger expanses "oceans," but they are all part of one gigantic World Ocean that is moving and changing-and affecting our lives-all the time.
More than eighty percent of our ocean is unmapped, unobserved, and unexplored. Much remains to be learned from exploring the mysteries of the deep.
Nepal is a country located in the Himalayan region, known for its unique geography, rich culture, and diverse ecosystems. One of Nepal's most valuable natural resources is water. The country is considered to be the second richest in water resources due to its geographic location, topography and climate.
Brazil has highest freshwater resources in the world which is accounts for approximately 12% of the world's freshwater resources. It is just because Amazon region this country contains 70% of the total freshwater. Russia has second largest freshwater reserve which is approximately 1/5 of freshwater in the world.
Rain water is considered the purest form of natural water.
