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 given processes are examples of 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, not their movement.

Answer: Erosion

2. Any process that breaks material like rock into small pieces.
- Weathering: This is the correct term because weathering involves the physical or chemical breakdown of rocks into smaller pieces without movement.
- Erosion: Erosion involves the movement of material, not just breaking it down.

Answer: Weathering

#### Part 2: Match Words with Photos
We need to match the given terms with the corresponding images. Let’s analyze each term and image:

1. Glacier: A large body of ice that moves slowly over land.
- Image f: Shows a large body of ice moving over land, which is characteristic of a glacier.

2. Erosion by gravity: The movement of material downhill due to the force of gravity.
- Image d: Shows loose rocks and debris that have moved downhill, indicating erosion by gravity.

3. Erosion by wind: The movement of material (e.g., sand) by wind.
- Image e: Shows sand dunes, which are formed by wind erosion as wind blows sand particles across the landscape.

4. Erosion by water: The movement of material by flowing water (e.g., rivers, streams).
- Image g: Shows a beach with waves, indicating erosion by water as waves carry sediment along the shoreline.

5. Weathering by plants: The breakdown of rocks due to the growth of plant roots or other plant activities.
- Image a: Shows a tree growing on rocky terrain, where the roots may be breaking down the rock over time.

6. Weathering by water: The breakdown of rocks due to the action of water (e.g., dissolving minerals, freezing/thawing cycles).
- Image b: Shows rock formations with visible cracks and layers, which could be the result of water seeping into cracks and causing expansion during freezing.

7. Deposition: The process where eroded material is deposited or left behind in a new location.
- Image c: Shows layered rock formations, which could be the result of deposition over time as sediments were laid down and compacted.

#### Final Matches:
1. Glacier → Image f
2. Erosion by gravity → Image d
3. Erosion by wind → Image e
4. Erosion by water → Image g
5. Weathering by plants → Image a
6. Weathering by water → Image b
7. Deposition → Image c

Final Answer:

1. Erosion
2. Weathering

Matchings:
- 1. Glacier → f
- 2. Erosion by gravity → d
- 3. Erosion by wind → e
- 4. Erosion by water → g
- 5. Weathering by plants → a
- 6. Weathering by water → b
- 7. Deposition → c
