The focus is the place inside Earth's crust where an earthquake originates. The point on the Earth's surface directly above the focus is the epicenter. When energy is released at the focus, seismic waves travel outward from that point in all directions.
Storms are caused by the collision of air masses that have different temperatures and humidities.
I am crossed between B and D but I think the answer is D because the mountains are in a high altitude so it is tall enough to touch the skies and with that the winds hit the mountains. <span />
Mountains are formed by the movements of the tectonic plates and Earth's. Movements deep beneath the Earth's surface cause a variety of reactions, and the results in different types of mountains. Mountains can form as a result of the volcanic activity, the collision of 2 tectonic plates or a movement along a fault line.
hope this helps
