the second largest continent of the globe. By its area (including Islands) — 30.3 million km2 it is second only to Eurasia. Africa is bordered on the North by the Mediterranean sea, in the North-East — the Red sea, in the East Indian ocean and on the West by the Atlantic ocean. The equator divides it almost in the middle, so warm all year round, and summer and winter differ only because one season is wet and the other dry. Along the equator stretches of moist Equatorial forest. The trees here all year round covered with leaves, their branches so intertwined that they form a continuous roof. Tree height is 40 to 80 m, they are covered with epiphytes — plants that live on trunks and branches of trees. Among them there are beautiful blooming orchids, a variety of ferns, mosses. Up the trunks climbing the vines trying to get closer to the light. The farther from the equator, the more rare it becomes the forest. Gradually he gives way to Savannah — endless steppes, covered with tall, to 4 m grass. Among Savannah there are individual trees of acacia and giant baobabs. Their leaves fall in the dry season. The farther from the equator the grass cover becomes smaller and poorer, to replace the Savannah comes to the desert. On the Ground, not a lot of places where there is no rain. However, in the interior of the Sahara is a territory where this event need to wait years, even decades. In places unexpectedly can pass rains, causing severe flooding. Within a few minutes the earth is covered with a layer of water from a height of human growth. Unexpected rain catches people by surprise, and many of them drown. Huge expanses of desert cover Sands and stony alluvial deposits, there are no rivers, plants rarely. To survive in these difficult conditions, plants must have long roots, reaching moisture deep under the earth, or thick trunks and leaves which can store water occasionally rains. Where on the earth's surface are sources of water, the desert is transformed. This oasis. They grow date trees and under their canopy — fruit trees, grapes, vegetables. In Africa they grow many healthy plants, coffee trees, oil and date palms, olive trees, sorghum, millet, Yam. They prepare in the forests of valuable timber (red, yellow, iron-tree).
