This set is all about pairing the right force with the right landform. Nine fill-ins walk you through caves dissolved in limestone, canyons cut by rivers, exfoliation peeling rock layers, sea arches punched through headlands, and cirques scooped out by small mountain glaciers. You'll also pick up vocabulary like sediment, deposition, and the chemical weathering caused by lichens.
Then comes a four-pair matching challenge: line up river water, ocean waves, wind, and glaciers with the V-shaped canyon, sea cliff, sand dune, and U-shaped valley each one creates. Nail this and you'll read landscapes like a geologist instead of guessing.
Style:
Weathering and Erosion
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Caves form when acidic groundwater dissolves limestone rock underground.
2. A canyon is a deep, narrow valley with steep sides carved by a river.
3. When temperature changes cause the outer layers of rock to peel off, it is called exfoliation.
4. Muddy river water shows that the river is carrying sediment downstream.
5. A sea arch is a natural opening through a rocky headland formed by wave erosion.
6. Lichens growing on rock surfaces cause slow chemical weathering by releasing acids.
7. A floodplain is an area of flat land built by repeated deposition of river sediment.
8. Animals that dig burrows contribute to physical weathering by breaking apart soil and rock.
9. A cirque is a bowl-shaped hollow carved into a mountainside by a small glacier.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each erosion agent to the landform it creates.
river water
→ V-shaped canyon
U-shaped valley
ocean waves
→ sea cliff
sea cliff
wind
→ sand dune
