A. What is erosion? Is it a slow or rapid process that causes changes in the earth?

What are landslides, volcanic eruptions, and earthquakes? Are they slow or rapid processes that cause changes in the earth?

What kind of changes do these four processes cause?

B. What natural processes cause rocks to break down into smaller pieces? Can water break rocks down into smaller pieces? Can the growth of roots cause rocks to break down into smaller pieces?
