The convection currents are the ones that create the force that breaks up and moves the crustal plates on the surface of the planet. By moving the crustal plates, the convection currents contribute to the formation of different types of plate boundaries, including the divergent plate boundaries.
The divergent plate boundaries are the boundaries where two plates are moving away from one another because the convection currents are dictating that kind of movement from bellow them. As they move away from each other, they leave a gap between them, and the convection currents push up a lot of magma towards the surface. The magma cools of very quickly in the water, thus forming rocks constantly, rocks that little by little start to make a big mas, that eventually turns into an underwater mountain, or rather a mid-ocean ridge.
Tropical. In this hot and humid zone, the average temperatures are greater than 64°F (18°C) year-round and there is more than 59 inches of precipitation each year.
Dry. These climate zones are so dry because moisture is rapidly evaporated from the air and there is very little precipitation.
Temperate. In this zone, there are typically warm and humid summers with thunderstorms and mild winters.
Continental. These regions have warm to cool summers and very cold winters. In the winter, this zone can experience snowstorms, strong winds, and very cold temperatures—sometimes falling below -22°F (-30°C)!
Polar. In the polar climate zones, it’s extremely cold. Even in summer, the temperatures here never go higher than 50°F (10°C)!
Need for raw materials because of the plentiful amount that is in Africa, such as gold, diamonds, wood, and coal.
