The African countries can easily be described and generalized, in the sense of the whole continent, as the economies are predominantly dependent on one or two products.
That dependence on one or two products is making very big problems, and it is also a very big mistake of the governments. When there's a slight variation in the prices on the certain product, the economies are heavily influenced, often in a bed manner.
It is weird though that the African countries have orientated their economies in this way, especially because the continent is very rich in lots of natural resources.

Answer:
tornadoes are formed by mixing cold and hot air together.
Explanation:
Because hot air rises, when hot air from the west, clashes with cold from the east (or visa versa) the hot air rises above the cold air and causes drag on the inside of the cold air, which makes the inside of the cold air travel at a slower rate than the outside of the cold air, which in turn makes the cold air turn in on itself.
because the cold air turns in on itself, any warmer air underneath rises above the swirl of cold air forcing it to sink to earths level. "friction" or "resistance" between the swirl of cold air and the earth's surface creates more energy that is absorbed by the cold air molecules in the swirl of air, allowing the particles to move quicker and quicker in the direction they are travelling in (a bend or circle), creating a tornado.
