Warm up: weathering and erosion
Before your investigation, let's warm up what you know about how Earth's surface changes. This is practice — it is not marked.
Practice questions
Q1. Is each example weathering or erosion? Write W or E.
| Example | W or E |
|---|---|
| Ice cracks a rock in place | |
| A river carries sand downstream | |
| Wind blows topsoil off a bare paddock | |
| Acid rain slowly dissolves a statue |
Q2. Put the three steps in order (1, 2, 3): deposition, erosion, transportation.
Q3. In your investigation, the "acid" washing out of the mine pile is an example of chemical weathering and erosion. What do you think a cover will do to how much washes out? Write your prediction.
Q4. Plan ahead: to keep your test fair, what is the ONE thing you will change, and two things you will keep the same?
| Change (one thing) | Keep the same |
