Why is it called Blue Planet?
Planet Earth has been called the “Blue Planet” due to the abundant water on its surface. Here on Earth, we take liquid water for granted; after all, our bodies are mostly made of water. However, liquid water is a rare commodity in our solar system. Liquid water covers most of the surface of our planet.
Where is our water found?
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 vapour, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in biological systems.
Which is Earth’s largest source of drinkable water?
Surface water is far easier to reach, so this becomes the most common source of potable water. About 321 billion gallons per day of surface water is used by humans. About 77 billion gallons of groundwater are used each day.
What is the main source of water on Earth?
There are two main sources of water: surface water and groundwater. Surface Water is found in lakes, rivers, and reservoirs. Groundwater lies under the surface of the land, where it travels through and fills openings in the rocks. The rocks that store and transmit groundwater are called aquifers.
Where is the most water located?
The ocean
Where is the freshest water on Earth?
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.
What are the top 3 reservoirs that hold water?
Throughout Earth’s history, water has been distributed between four distinct reservoirs—the oceans, ice sheets and glaciers (the cryosphere), terrestrial storage and the atmosphere. Today, the oceans contain about 96.5% of all Earth’s water with an average salinity of around 35 grams of salt per kilogram of seawater.

Which is the deepest river in the world?
The Congo River in Central Africa is one of the world’s great rivers, carrying 1.25 million cubic feet of water—more than 13 Olympic-sized swimming pools—into the Atlantic Ocean every second. That’s more flow than any other river in the world that’s not the Amazon.
