Western Asia. Final review

To review, compare the continents by main indicators. Eurasia is the largest (about 54 million km²), its highest point Everest (8 848 m). Africa is second (about 30 million km²), the equator crosses its middle, Kilimanjaro is 5 895 m and the Nile is one of the world’s longest rivers. North America is third, with Denali 6 190 m and the Great Lakes. South America is fourth, with Aconcagua 6 961 m, the Amazon (the fullest river) and Angel Falls 979 m. Antarctica is the highest, coldest and driest continent, covered with ice. Australia is the smallest continent, with Mount Kosciuszko. Oceans: the Pacific is the largest and deepest (Mariana Trench about 10 900 m), the Atlantic is second, the Indian third, and the Arctic the smallest and shallowest. Climate zones change from the equator to the pole; natural zones follow the climate by latitude and, in mountains, by altitude. On every continent population and natural resources are unevenly spread; human activity changes nature, so reserves and national parks are needed. As you saw in this course, some figures in textbooks get updated (for example Denali is 6 190 m and India is now first in population); so keep checking newer sources too.
