Answer to Question 1

Answer: Human activities have increased the rate of surface modification through such activities as deforestation and agriculture. These activities have increased the rate of erosion and deposition, thereby modifying landform development.

Answer to Question 2

Answer: As water moves perpendicular to the shoreline, the breaking waves provide the energy to push the water parallel to the shore, creating the longshore current. The longshore current acts like a river and transports material along the shoreline through longshore transport from areas where it is eroded by waves to areas of less energy where it will be deposited.
