Answer: convergent plate boundries
Explanation:
At convergent plate boundaries, where two continental plates collide earthquakes are deep and also very powerful. In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
The dust bowl was caused by a strong wind of erosion.
The Red Sea and the Suez Canal are of strategic value in the region because this is one of the most important transport points for oil in the entire world. Much of the oil that comes from the Persian Gulf travels through the Suez Canal on its way to Europe and the United States. Control and stability of this area is of vital importance to the United States and European governments and markets.
The correct answer is letter B. Horizontal water movements. Upwelling is a phenomenon that involves the dense's motion because of the wind. It is cooler and makes the water rich in nutrients towards the ocean surface. The warmer air is replaced and nutrient-depleted surface water are also replaced. This makes increase in plankton population and increase in nutrients at the ocean surface. The movement of the water is vertically up.
