Earthquakes and volcanic eruptions are examples of rapid events that are caused by the movement of earth's mountain building is a much more slow process, which is caused by the movement of earth's a. ocean tides; crustal plates b. ocean tides; winds c. crustal plates; crustal plates d. crustal plates; ocean tides

The correct answer is - C. Crustal plates, crustal plates.

The movement of the crustal plates of the Earth is the reason why the geologic processes are occurring on our planet. With their movement, the crustal plates manage to create lot of pressure, open up gaps for the magma from the mantle, as well as make adjustments deeper into the ground.

Because of the adjustments deep into the ground, or rather the crust, lot of force is released, manifested as strong and very quick vibrations, better known as earthquakes.

The gaps that are opening between the plates let the magma reach the surface, thus enabling the volcanic activities on the planet.

The pressure from the plates' collision makes the land lift up slowly, and over time a mountain range starts to form because of the continuous lifting up of the area.
