Let’s think about how wind and a fast-running river can cause erosion, weathering, and deposition — using the picture as a guide (even though we’re not describing it).

Step 1: Understand what each term means
-
Weathering = breaking down rocks into smaller pieces (like crumbs from a cookie). It doesn’t move them — just breaks them.
-
Erosion = moving those broken pieces away (like blowing cookie crumbs off the table).
-
Deposition = dropping those pieces somewhere else (like when the wind stops blowing and the crumbs fall on the floor).

Step 2: Think about wind
Wind can:
- Blow sand against rocks → that’s
weathering (it chips away at the rock over time).
- Pick up small bits of dirt or sand → that’s
erosion (moving them).
- Drop them when it slows down → that’s
deposition (like making little piles of sand).
---
Step 3: Think about a fast-running river
A fast river can:
- Smash water and rocks together → that’s
weathering (breaking rocks apart).
- Carry mud, sand, and pebbles downstream → that’s
erosion (moving them).
- Slow down in calm areas and drop what it’s carrying → that’s
deposition (making new land or sandbars).

Step 4: Put it all together for each section
We need to write short answers for Erosion, Weathering, and Deposition — explaining how BOTH wind and the river do each one.

✔ Final Answer:
Erosion:
Wind picks up loose soil and sand and carries it away. The fast river grabs rocks, mud, and sand from the banks and bottom and moves them downstream.
Weathering:
Wind blows sand against rocks, slowly wearing them down. The river smashes water and rocks together, cracking and breaking them into smaller pieces.
Deposition:
When the wind slows down, it drops the sand and dust it was carrying. When the river slows down (like in a bend or flat area), it drops the mud, sand, and pebbles it was moving.
