Hint:We will discuss the location of the continent to tell about the temperature of the area. The Equator passes almost through the middle of Africa. Thus, a major part of the continent lies in the tropical or Torrid Zone.
Since the Torrid Zone receives the direct rays of the sun all through the year, most of Africa has a hot climate. However, the high mountains and plateaus have a moderate temperature. The moderating influence of the sea is felt along the coastal areas. The distribution of rainfall varies greatly from place to place. Africa receives two hundred fifty to five hundred cm rainfall on an average annually. The prevailing winds like Trade winds and Westerlies and water bodies also have a moderating influence on the temperature of certain places in Africa. These are found on both sides of the savanna region. In the north lies the vast Sahara s Desert and in the south are the Namib and the Kalahari desert Here summers are extremely hot and winters are cool. There is a great difference between day and night temperatures, Rainfall is very scanty. Strong winds are common during the day.
Hence, the correct answer is option (C).
Note:Since the climate is hot and dry, M desert vegetation consists of very few trees. Shrubs tr and thorny bushes are found here. They have natural adaptations like long roots, waxy stems, spiny leaves th etc to survive in such conditions.
