Fault
Which of the following is responsible for the movement of tectonic plates?
Covection cells
In Investigation 7.1 you watched how melted wax reacted when poured on a flat surface, a sloped surface, and in cold water. Which of the following best describes what happened when the wax was poured into the cold water?
The wax cooled as it hit the water and formed a hardened blob just under the surface of the water.

Which of the following is NOT true about wind erosion?
Areas with heavy vegetation experience more wind erosion.
