Weather, Erosion, and Deposition

The earth is built up and torn down in many ways. Physical and chemical weathering are processes which are very important in making soil. Which statement accurately describes an example of chemical weathering?

• In order for rock to become metamorphic rock, it must be heated and extreme pressure applied.

• In Alaska, rocks are broken due to continuous freezing and thawing of water sitting in cracks.

• Beautiful and strange rocks, shaped by blowing sand, dot the Western United States landscape.

• Sinkholes are formed in central Florida as seeping water dissolves underground limestone rocks

On October 4, 2005, Hurricane Wilma swept through South Florida causing devastating damage. Thousands of trees were blown over and uprooted. The 125 mph winds blew debris all over the place and in some instances blocking storm drains. This caused the flooding of streets and yards. Along the western coast near Naples, storm surge washed away large areas of the beach and also caused street flooding. Power lines were knocked down and people were without power for days. Which of the following statements correctly identifies the processes involved in the hurricane’s devastation?

• The windblown debris, caused by mechanical weathering, resulted in damage

• The effects of the flooding reflect damage caused by mechanical weathering.

• The washed away beach represents the damage caused by erosion

• The uprooted trees are an example of damage caused by erosion.
