How much water is on and above the earth?

All Earth's water, liquid water, and water in lakes and rivers

Show Area:
(1) All water (the largest location in the western North American nation region, 860 mi (1,385 km) in diameter)
(2) recently ground within liquid water, lakes, marshes and rivers (area above medium-sized Kentucky, 1895.5 mi (2.52 kilometers) in diameter), and
(3) Water lakes and rivers (the smallest place on Georgia, 37.7 mi (54.2 km) N diameter).

Earth can be a watery place. However, what proportion of water is present above our planet? About seventy-one p.c of the surface is roofed with water, and also the oceans hold about ninety-six p.c of all the Earth's water. Water is a gift of water within the air, in rivers and lakes, in snowflakes and glaciers, in wet and aquatic forms under the ground, and even within you and your dog.

The water is rarely empty. Due to the water cycle, the convenience of our planet is constantly changing from one place to another and in a way. Despite the water cycle, things become very stale!

All the water within the earth in an excessive bubble

The globe has depicted blue areas representing the relative amount of Earth's water compared to Earth's size. Are you stunned that these waterballs look so low? They are perfectly small along the dimensions of the planet. This image tries to indicate 3 dimensions, so each space represents a "volume". The largest area representing all waters over and above the planet would be approximately 332,500,000 blockish miles (mi3) (1,386,000,000 blockish kilometers (km3)) and about 860 miles (approximately one, 385 kilometers) in diameter.

The small region above Kentucky constitute the earth's liquor freshwater in groundwater, marshwater, rivers, and lakes. The area will have an area of ​​approximately 2,551,000 mi3 (10,633,450 km3) and about 169.5 mi (272.8 km) in diameter. Yes, all this water is fresh water, which we all need every day, but most of it is deep in the ground, which is unavailable to humans.

Do you observe the "tiny" bubble above Atlanta, Georgia? It represents fresh water in all lakes and rivers on the planet. Most of the water needs and life needs on earth come from these surface water sources. The volume of this sphere is 22,339 mi3 (93,113 km3). The diameter of this sphere is about 34.9 mi (56.2 km). Yes, Lake Michigan looks much larger than this area, but you have to try to imagine a bubble about 35 miles high - while the average depth of Lake Michigan is smaller than 200 +100 feet (91 meters).

There is water on the earth

More than 96 percent, the vast majority of the water on the Earth's surface is saltwater in the oceans. Freshwater resources, such as water falling from the sky and into rivers, drains, lakes and groundwater, provide people with the water they need every day to live. It is easy to imagine water sitting on the surface of the Earth, and your view of the water cycle may be that rain fills rivers and lakes. But, undiscovered water under our feet is also critically important to life. How do rivers flow after a week without rain? In fact, how do you calculate the water flowing down the waterway when there is no rain one day? The answer is that our water supply is more than just surface water, there is also a lot of water under our feet.

Even though you can only see water on the surface of the Earth, there is too much fresh water stored in liquid form on the surface. In fact, some of the water that you pour into the rivers seeps from the ground water into the river bed. The rain water continuously leaks into the ground to recharge the aquifers, while the water present in the ground recharges the rivers by continuously leaking.

Humans are happy because it is because we use both types of water. In the United States (USA) in 2010, we used approximately 275 billion (275,000,000,000) gallons (1,041 billion liters) of surface water per day, and approximately 79.3 billion (79,300,000,000) gallons (300.2 billion liters) per day of groundwater. Although surface water is used more to supply drinking water and to irrigate crops, groundwater is important in that it not only helps keep rivers and lakes full, but also in those places Provides water to people where there is little visible water, such as desert cities in the western United States. lack of groundwater, people would go sand-surfer in Palm Springs, California rather of playing golf.

How much water is on the earth (and)? Here are some numbers you can think of:

If whole of Earth's waters (oceans, glaciers and glaciers, lakes, rivers, groundwater, and atmosphere) are shed into a field, the diameter of that field will be about 860 miles (about 1,385 kilometers), little more. The quantity of all water will be around 332.5 million (1.386 × 10²¹ litres) cubic miles (mi3) or 1,386 million cubic kilometers (km3). One cubic mile of water is over 1.1 trillion gallons. One cubic kilometer of water equals 264 billion gallons (1 trillion liters).

About 3,100 mi3 (12,900 km3) of water, mostly in the form of water vapor, occurs at any given time in the atmosphere. If it all falls as rain at once, the earth will be covered with only 1 inch of water.

48 contiguous (less 48 states) The United States receives about 4 mi 3 (17.7 km 3) of rainfall every day.

Each day, 280 mi 3 (1,170 km 3) of water evaporates or spreads to the atmosphere.

If whole the world's water was dropped in the United States, it would covering the land to a profundity of about 107 miles (145 mi).

Fresh water on earth accumulates in the ground much more than rivers and lakes. More than 2,000,000 mi 3 (8,400,000 km 3) is kept in the Earth in freshwater, which is within 1/2 mile of the surface. But, if you actually want to investigate freshwater, most of the 7,000,000 mi3 (29,200,000 km3) is kept in water, which is found in glaciers and ice caps, mostly in the polar regions and in Greenland.
