Ready to dig deeper into how rock and soil change? Nine fill-ins cover sinkholes collapsing over dissolved limestone, gravity dragging debris downslope, alluvial fans spreading at the base of mountains, frost wedging cracking rock, carbonation from carbon dioxide and water, and the striations glaciers grind into bedrock. You'll also meet stalactites and sea stacks along the way.
The matching section pairs four deposition features — floodplain, alluvial fan, barrier island, and stalactite — with their descriptions. By the end, you'll connect specific weathering processes to the exact changes they cause in the world outside your window.
Style:
Weathering and Erosion
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A sinkhole forms when underground limestone dissolves and the surface collapses.
2. The force of gravity pulls loose rocks and soil down steep slopes.
3. An alluvial fan is a triangle-shaped deposit of sediment at the base of a mountain.
4. Stalactites and stalagmites inside caves are formed by the deposition of dissolved minerals.
5. When water enters rock cracks and freezes, it expands and causes frost wedging.
6. Windbreaks are rows of trees planted to reduce wind erosion on farmland.
7. Carbonation is a type of chemical weathering caused by carbon dioxide mixing with water.
8. A sea stack is a tall column of rock left standing after waves erode the cliff around it.
9. Glacial striations are long, parallel scratches left on bedrock by rocks frozen in moving ice.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each deposition feature to its description.
floodplain
→ flat area beside a river built by flood sediment
mineral deposit hanging from a cave ceiling
alluvial fan
→ fan-shaped deposit at the base of a slope
long sandy island formed by coastal deposition
barrier island
→ long sandy island formed by coastal deposition
flat area beside a river built by flood sediment
stalactite
→ mineral deposit hanging from a cave ceiling
fan-shaped deposit at the base of a slope
