4.Observe the map of world`s average annual precipitation(opposite)
(a)Describe the changes in rainfall that occurs as you move from the southern to the northern tip of Africa. In the southern tip of Africa, there's like 500-1000mm of the average annual rainfall, but in the northern tip, the annual rainfall is under 250mm which means from south to north, the rainfall decreases.

(a)Which parts of the world appear to have a large amount of water available per person? Philippines, Papua New Guinea, Russia, almost most of the parts of Australia, Central Africa, Canada, the upper part of South America and Costa Rica.
(b)Which parts of the world appear to have a small amount of water available per person? Almost most parts of China, Mongolia,  The Middle East, The north west part of Africa, the southern part of Australia, Japan, and most parts of Europe.

(a)what are the main uses of water? The main uses of water is with the reservoir.
