Earth's Physical features

                                     Earth's Physical features

MOST OF THE EARTH SURFACE (about 70 per cent) is covered with water. The largest single body of water, the Pacific Ocean, alone cover about 30 per cent of surface. Most of the land distributed as seven continents; these are (from largest to small) Asia, Africa, North America, South America , Antarctica, Europe, and Australasia. The physical feature of the land are remarkably varied. Among The most notable are mountain ranges , rivers , and desert. The largest mountain ranges the Himalayas in Asia and the Andes in South America extend for thousand of kilometers. The Himalayas included the world's highest mountain. Mount Everest  (8,848 meters). The longest rivers are Rivers Nile in Africa (6,695 Kilometers). Desert cover about 20 per cent of the total land area. The largest is the Sahara, which covers nearly a third of Africa. The Earth's surface feature can be represented in various ways. Only a globe can correctly represent areas , shape, size, and direction, because there is always distortion when a spherical surface the Earth's, for example is projected on the flat surface of the map. Each map projection is therefore compromise: it shows some features accurately but distorts others. Even satellite mapping does not produce completely accurate maps, although they can show physical features with great clarity.
