What is the slowest agent of erosion?
Gravity is an agent of erosion... I'm not quite sure if it is erosion. In the science textbook I have right in front of me it says and I quote, "Gravity, running water, waves, wind and glaciers are all causes, or agents, of erosion. Although it says it's an agent of erosion it doesn't say it is erosion. An agent is a "cause" of something.
