To Unify by Perception Religions. A Universe From Nothing' by Lawrence Krauss, AAI 2009. Intelligent Design? The Flood. Water in Earth's upper mantle. Water Distribution. The USGS Water Science School "Water, Water, Everywhere.... "You've heard the phrase, and for water, it really is true. Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.
Below are two representations of where Earth's water resides. The left-side bar chart shows how almost all of Earth's water is saline and is found in the oceans. The globe image represents how much actual water exists, compared to the total size of the Earth. Distribution of Earth's Water In the first bar, notice how only 2.5% of Earth's water is freshwater - the amount needed for life to survive. View a larger version of this image and learn more. All of the World's Water Earth's freshwater.
Volume of Earth's Oceans. Topic index | author index | special index You've heard it all before: 70 percent of the earth is covered in water! But what does that really mean? These waters that are spoken of have a breakdown into five different categories: Oceans, rivers, lakes, groundwater, and ice. As an essential part of our daily diet, water is vital for the survival of our ecosystem. The world's oceans comprise 97.3% of the total water on earth and consists of 5 oceans: Atlantic, Pacific, Indian, Arctic, and Southern. The current range for the volume of the world's ocean is from 1.3 to 1.5 billion cubic kilometers and it will still get larger and larger as time passes. There are two origins of water: comets (extraterrestrial bombardment) and out gassing (condensation of steam from early volcanism).
Ketsia Erra -- 2008 We as humans don't realize the significance of water on earth. The volume of the Earth's oceans is approximately 1.3 × 109 km3. The average depth of the oceans is 2.5 miles (4 km). Syed S.
