What Erosion Is

• The picking up of rocks. Earth's surface is
  always changing. Sometimes it changes very
  quickly . Sometimes it changes so slowly that it
  is hard to observe. The three agents of erosion.
  How does erosion occur? There are three major
  tools, or agents, of erosion. These are water,
  wind, and ice. Erosion is the process that picks
• up and carries away these materials.
