Students explain why steep hillsides erode faster, identify what process pitted a marble statue, and name the human activity that most speeds up erosion. Part B has five fill-in-the-blank problems about terracing, sea arch formation, and the reddish color oxidation produces in iron-bearing rocks.
Human impact on erosion and real-world weathering examples connect Earth science concepts to environmental problems students will encounter throughout their lives.

Weathering and Erosion
Part A: Multiple Choice
Circle the best answer for each question.
1. Which best explains why soil on a steep hill erodes faster than soil on flat ground?
A) The hill has more rain
B) Gravity pulls water and soil downhill faster on steep slopes
C) Flat ground has no gravity
D) Hills are made of softer rock
2. A statue made of marble has become rough and pitted after 200 years outdoors. What most likely caused this?
A) Physical weathering from sunlight
B) Chemical weathering from acid rain
C) Erosion from strong winds
D) Deposition of new minerals
3. Which human activity can speed up erosion the most?
A) Planting trees on hillsides
B) Building terraces on slopes
C) Clearing forests for farmland
D) Adding mulch to gardens
4. What is the correct order of events that forms a delta?
A) Deposition, erosion, weathering
B) Weathering, erosion, deposition
C) Erosion, deposition, weathering
D) Deposition, weathering, erosion
Part B: Fill in the Blank
Write the correct answer on each line.
1. Terracing farmland on hillsides helps slow erosion by creating flat steps.
2. A sea arch forms when waves erode both sides of a rocky headland.
3. Oxidation is a type of chemical weathering that causes iron-bearing rocks to turn red.
4. The movement of large amounts of rock and soil down a slope is called mass wasting.
5. Barrier islands are formed by the deposition of sand along a coast.
