The correct answer is:
C. A landslide is a fast process that occurs on a large scale.
Fast and Slow Geologic Processes
Fast and Slow Geologic Processes
The Earth's surface is a dynamic system that changes with the activity of many large-scale and small-scale geoscience processes. Geoscience processes occur at different time scales where some processes happen quickly, and others can take millions of years. The processes occur at different spatial scales with some creating microscopic changes, and others affecting large areas.
The table describes some of the processes that can change Earth's surface.
Process Example
Landslide A large number of rocks break from an outcrop and slide down a slope.
Uplift Two continental plates collide, thrusting rock upward and creating a mountain chain.
Erosion Flowing water moves weathered materials along a river.
Tsunami An underwater earthquake causes large waves to roll on the shore.
Deposition Wind moves sediment to a new location.
Earthquake Two plates slide past each other which causes the ground to shake.
Volcanic eruption Lava erupts and flows out of a volcano.
