Earth, the blue planet: the oceans combined with the atmosphere makes the planet look blue. So its color mainly comes from water. About 71% of the Earth’s surface is covered with water, in fact, Earth is still the only planet we know where water can exist in liquid form on the surface. Water is also vital for all known forms of life. But there are numerous places on Earth that receive rainfall less than even 0.76 mm annually. One place even receives absolutely no rainfall. Here are the top ten driest places on Earth.

Here some numbers: the Earth has a diameter of about 12,735 kilometers (on average). The highest point on Earth is the top of Mt. Everest, at 8.85 km. The deepest point on Earth is the Mariana Trench, at about 11 km deep. Make the calculations and you can see, the Earth definitely would NOT look like below without water:

The world’s deepest lake is the Lake Baikal, which has a depth of 1,642 meters (5,387 feet). It is a rift lake in the south of the Russian region of Siberia. Its bottom is at 4,215 feet (1,285 meters) below the sea level. In terms of volume, Lake Baikal is also the world’s largest freshwater lake; it contains roughly 20% of the world’s unfrozen surface fresh water with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.

The standard maps we see every day use Mercator Projection, a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It developed for navigational purposes, has often been used in world maps. And like all the other types of projections, it can be deceptive.

In fact, every map tells lie, since it’s impossible to transform perfectly the three-dimensional world into two-dimensional surfaces like paper or computer screen. Map projections are necessary for creating maps and every map projections distort the surface in some fashion (a map projection is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane).
