Have you ever wondered how much water is on the Earth, well most of you say, it covers two third of the earth and should be in pretty huge amount. Its true, but applies only when compared to the surface area of the land.
When you compare the size of the entire earth with that of the total water present in, on and above the earth then here’s what you get.
The US Geological Survey has made an awesome visualization that visually compares the solid earth and the entire water that belongs to the planet.
Size of Earth vs Total Water in, on and above Earth
The sphere includes all the water in the oceans, ice caps, lakes, and rivers, as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant. The sphere representing water appears so small in relation to the size of the Earth. See larger image from Source (USGS)
Breaking down the water sphere
The following image shows various blue spheres representing relative amounts of Earth’s water in comparison to the size of the Earth.
1. The largest Sphere represents all water in, on and above the earth – The size of the Sphere is 860 miles (about 1,385 kilometers) in diameter
2. The smaller sphere represents liquid fresh water, present as ground water, swamp water, rivers and lakes of which 99 percent is groundwater, much of which is not accessible to humans. – The size of the Sphere is 169.5 miles (272.8 kilometers) in diameter
3. The tiny third Sphere represents fresh water in all the lakes and rivers – The size of the Sphere is about 34.9 miles (56.2 kilometers)
Fascinating Facts about Earth
1. The Highest point on Earth is the Mount Everest Peak in Nepal – 8,848 m ( about 8.8 Km)
2. The Deepest point on Earth is in the Mariana Trench in Pacific Ocean – 10,971 m (about 11 Km)
3. The Mean Radius of Earth is 6,371.0 km , which means you have to travel 6,371 Km deep to reach the center point of the Earth
