Students complete nine sentences about tree roots causing physical weathering, carbonic acid dissolving limestone, and a fast-flowing river carving a V-shaped valley. The matching activity pairs physical weathering, chemical weathering, erosion, and deposition with their descriptions.
Matching all four Earth surface processes in one activity reinforces the precise distinctions between in-place rock breakdown, particle transport, and sediment deposit in a new location.
Style:
Weathering and Erosion
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Tree roots growing into rock cracks cause physical weathering.
2. When carbon dioxide mixes with rainwater it forms a weak acid that dissolves limestone.
3. A V-shaped valley is carved by a fast-flowing river.
4. Wind erosion is strongest in flat, dry areas like deserts.
5. Gravity pulls loose rocks downhill in an event called a landslide.
6. A moraine is a ridge of sediment left behind by a glacier.
7. Ocean waves erode cliffs along the coastline.
8. Sediment that settles at the bottom of a lake is an example of deposition.
9. The repeated freezing and thawing of water in rock cracks is called frost wedging.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
physical weathering
→ rock broken by ice or roots
sediment dropped in a new place
chemical weathering
→ minerals changed by acid rain
rock broken by ice or roots
erosion
→ sediment carried away by wind or water
minerals changed by acid rain
deposition
→ sediment dropped in a new place
sediment carried away by wind or water
