What percentage of the earth's surface is covered in water? 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.

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.

The ocean plays a starring role in whatever happens with the environment.

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.

The Earth has lost a quarter of its water This finding can be used to show that back in time there was more water on Earth than today. (Photo:Colourbox) Although water covers 70 percent of the Earth's surface, water is actually a rare substance that represents just 0.05 percent of the Earth's total mass. Water has nevertheless played a crucial role in the emergence of life on Earth.

River birch (Betula nigra) Propagation Method. Seed collection: River birch fruit are small nutlets held together in a catkin-like aggregate of fruits called strobiles. Fruits can be collected in the spring in May to June just as they turn from green to brown. The fruits will separate from the catkin-like aggregate and be spread by wind.

- EARTH'S OCEANS Oceans cover about 70% of the Earth's surface. The oceans contain roughly 97% of the Earth's water supply. The oceans of Earth are unique in our Solar System. No other planet in our Solar System has liquid water (although recent finds on Mars indicate that Mars may have had some liquid water in the recent past).

The Earth has lost a quarter of its water This finding can be used to show that back in time there was more water on Earth than today. Although water covers 70 percent of the Earth's surface, water is actually a rare substance that represents just 0.05 percent of the Earth's total mass. Water has nevertheless played a crucial role in the emergence of life on Earth. Without water, the Earth would in all likelihood be a dead planet. The amount of water on the planet has not always been the same, however. A research group at the Natural History Museum of Denmark has discovered this by measuring how hydrogen isotope ratios in the oceans have changed over time.

Ocean Saline water covers approximately 360,000,000 km 2 (140,000,000 sq mi) and is customarily divided into several principal oceans and smaller seas, with the ocean covering approximately 71% of Earth's surface and 90% of the Earth's biosphere. The ocean contains 97% of Earth's water, and oceanographers have stated that less than 5% of the World Ocean has been explored.

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. An estimated 1.5 to 11 times the amount of water in the oceans may be found hundreds of miles deep within the Earth's interior, a

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.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.

How much water is there on Earth? ­The oceans are huge. About 70 percent of the planet is covered in ocean, and the average depth of the ocean is several thousand feet (about 1,000 meters). Ninety-eight percent of the water on the planet is in the oceans, and therefore is unusable for drinking because of the salt.

Early Earth âwas covered in waterâ Earth was once a ‘waterworld’ much like the one depicted by Hollywood, scientists believe. A new model of the early Earth suggests that until around 2.5 billion years ago oceans covered almost the whole of the planet. Just 2% to 3% of the Earth’s surface would have been dry land, compared with 28% today. Earth was once a ‘waterworld’, scientists believe. The Earth at that time may have resembled the way it looked in Waterworld, the 1995 post-apocalyptic sci-fi movie starring Kevin Costner. In the film, humanity struggles to survive after the ice caps melt and inundate the planet with water.

How Much Water Is on Earth? Oceans create a water layer spanning 15,000 miles (24,000 kilometers) across the planet at an average depth of more than 2 miles (3.2 km). If you poured all of the world's water on the United States and could contain it, you'd create a lake 90 miles (145 km) deep.
