The earth’s surface

The surface of the earth is divided into land and water. 70.8 percent of the earth consists of water and 29.2 percent consists of land. If you look in an atlas, you can see that there are three large oceans: the Pacific Ocean, the Atlantic Ocean and the Indian Ocean. The largest parts of land can be found on the Northern Hemisphere (North-America, Europe and Asia). On the Southern Hemisphere, the continents are mostly pointed (South-America and Africa) in the direction of the South Pole.

The earth’s surface can also be divided up vertically, when you look at the differences in height. The highest mountain on earth, the Mount Everest in the Himalayans, is 8850 metres high. Compare the highest mountain in Europe - Mont Blanc. It is ‘only’ 4807 metres high. The deepest valley lies more than 11 kilometres below sea level in the ‘Marianen’ trough near the Philippines. The extreme heights and depths such as these are quite rare. The average height of land in relation to the sea level is 875 metres.
