Weathering and erosion interactive activity - Free Printable

Problem Analysis:

The task involves understanding the concepts of weathering and erosion and applying them to match descriptions with images. Let's break it down step by step.

---

#### Part 1: Circle the Right Word
We need to identify whether the process described is weathering or erosion.

1. The process that moves weathered material away from where it came originally.
- Erosion: This is the correct term because erosion involves the movement of weathered material (e.g., soil, rock fragments) from one place to another.
- Weathering: Weathering refers to the breakdown of rocks in place, without moving the material.

Answer: Erosion

2. Any process that breaks material like rock into small pieces.
- Weathering: This is the correct term because weathering involves the physical and chemical breakdown of rocks into smaller pieces.
- Erosion: Erosion does not involve breaking down rocks; it involves moving the already broken-down material.

Answer: Weathering

#### Part 2: Match Words with Photos
We need to match the given words (1–7) with the corresponding photos (a–g). Let’s analyze each photo and determine which process it represents.

##### Photos Analysis:
1. Photo (a): Shows a tree growing on rocky terrain.
- This is an example of weathering by plants because plant roots can break apart rocks as they grow.

2. Photo (b): Shows a cliff with layered rock formations.
- This is an example of erosion by water because water (rain, rivers, etc.) can carve through rock over time, creating such formations.

3. Photo (c): Shows a sandstone formation with smooth, curved layers.
- This is an example of erosion by wind because wind can erode soft rocks like sandstone, creating smooth, sculpted shapes.

4. Photo (d): Shows a pile of loose rocks and debris.
- This is an example of deposition, where eroded material is deposited (dropped off) in a new location.

5. Photo (e): Shows a sand dune.
- This is an example of erosion by wind, as wind can move sand particles and create dunes.

6. Photo (f): Shows a glacier.
- This is an example of a glacier, which is a large mass of ice that moves slowly over land, causing erosion.

7. Photo (g): Shows a beach with waves crashing onto the shore.
- This is an example of erosion by water, as waves can erode coastal areas over time.

##### Matching:
- 1. Glacier: Photo (f)
- 2. Erosion by gravity: Not directly visible in any photo, but could be inferred from some images (e.g., loose rocks in photo (d)).
- 3. Erosion by wind: Photos (c) and (e)
- 4. Erosion by water: Photos (b) and (g)
- 5. Weathering by plants: Photo (a)
- 6. Weathering by water: Not directly visible in any photo, but could be inferred from some images (e.g., water erosion in photo (b)).
- 7. Deposition: Photo (d)

#### Final Answers:
1. Which is correct? Circle the right word.
- 1. Erosion
- 2. Weathering

2. What do these photos show? Match words (1–7) with photos (a–g).
- 1. Glacier: (f)
- 2. Erosion by gravity: Not directly visible
- 3. Erosion by wind: (c), (e)
- 4. Erosion by water: (b), (g)
- 5. Weathering by plants: (a)
- 6. Weathering by water: Not directly visible
- 7. Deposition: (d)

Final Answer:

\boxed{
\begin{array}{ll}
\text{1. Erosion} & \text{2. Weathering} \\
\text{1. Glacier: (f)} & \text{2. Erosion by gravity: Not directly visible} \\
\text{3. Erosion by wind: (c), (e)} & \text{4. Erosion by water: (b), (g)} \\
\text{5. Weathering by plants: (a)} & \text{6. Weathering by water: Not directly visible} \\
\text{7. Deposition: (d)} &
\end{array}
