Question

Accepted Answer

### ACTIVITY 4: True or False

1. **Brief Explanations**: Wind erosion is known to displace fertile topsoil, so the statement is accurate.
   **Answer**: True

2. **Brief Explanations**: Deflation (wind erosion) removes fine particles, leaving behind rocky, smooth surfaces (ventifacts or desert pavement).
   **Answer**: True

3. **Brief Explanations**: Loess soils are rich in nutrients (fine wind - deposited silt) and are highly fertile for farming. Thus, the statement is false.
   **Answer**: False. This statement is false because loess soils are fertile and good for farming due to their fine, wind - deposited silt content.

4. **Brief Explanations**: When wind - blown sand strikes rocks, it causes abrasion (wearing down of rocks).
   **Answer**: True

5. **Brief Explanations**: Dunes are moved by wind, so they do not stay in the same place. Thus, the statement is false.
   **Answer**: False. This statement is false because dunes are mobile and can be moved by wind, so they do not always stay in the same place.

### ACTIVITY 5: Venn Diagram (Compare Processes)

- **Left circle (Wind Erosion)**: Statements describing actions of removing or displacing soil.
  - 1 (Removes soil from the land)
  - 4 (Causes loss of fertile topsoil)

- **Right circle (Wind Deposition)**: Statements describing actions of depositing sediments.
  - 2 (Creates sand dunes)
  - 5 (Drops sediments when the wind slows down)

- **Middle (Both)**: Statements applicable to both erosion (movement) and deposition (movement - related or landscape change).
  - 3 (Moves sediments by wind)
  - 6 (Can change landscapes over time)

For the multiple - choice questions at the top:

4. **Brief Explanations**: Wind depositing sand forms sand dunes; canyons are formed by water erosion, volcanoes by volcanic activity, and glaciers by ice.
   **Answer**: C. Sand dune.

5. **Brief Explanations**: Star dunes form where wind direction changes frequently (multiple wind directions shape them). Barchan dunes form with a single wind direction, longitudinal with parallel wind, and parabolic with vegetation - anchored ends.
   **Answer**: D. Star

6. **Brief Explanations**: Loess is fine wind - deposited silt that creates fertile soil (not large sand dunes).
   **Answer**: B. Fine wind - deposited silt that creates fertile soil
