Step-by-step solution for: Free Printable Weathering Erosion and Deposition Worksheet
Let's analyze each of the six images in the worksheet and determine whether weathering, erosion, or deposition is occurring (or has occurred), and identify the responsible factors.
---
- Observation: A large rock formation near the ocean, with visible water at its base and some erosion at the bottom.
- Explanation: This shows erosion. The sea waves are continuously hitting the rock, breaking it down and carrying away particles.
- Factors Responsible:
- Water (waves) – primary agent of erosion here.
- Weathering may also be occurring (e.g., salt crystallization, freeze-thaw cycles).
- Time – long-term exposure to ocean conditions.
> ✔ Process: Erosion
> 🔹 Factors: Ocean waves, water, time
---
- Observation: A stone wall with visible cracks and layers separating, possibly due to expansion and contraction.
- Explanation: This is weathering, specifically physical weathering caused by temperature changes or water freezing in cracks.
- Factors Responsible:
- Temperature changes – expansion and contraction of rocks.
- Freeze-thaw action – water enters cracks, freezes, expands, and breaks the rock.
- Moisture – presence of water contributes to cracking.
> ✔ Process: Weathering
> 🔹 Factors: Temperature changes, water, freeze-thaw cycles
---
- Observation: Dry, cracked soil with a small green plant growing through it.
- Explanation: This shows weathering (specifically biological weathering) and possibly erosion if wind or rain is involved later.
- Factors Responsible:
- Biological weathering – plant roots grow into cracks and widen them.
- Drying and shrinking – soil loses moisture and cracks.
- Sunlight and heat – contribute to drying.
- Wind – could cause erosion of loose particles.
> ✔ Process: Weathering (biological and physical)
> 🔹 Factors: Plant roots, drying, temperature, wind
---
- Observation: A sandstone arch formed by natural processes.
- Explanation: This is a result of weathering and erosion over millions of years. The arch forms when softer rock erodes faster than harder rock.
- Factors Responsible:
- Wind erosion – carries away loose particles.
- Water erosion – from rain and runoff.
- Physical weathering – freeze-thaw cycles break down rock.
- Time – gradual process.
> ✔ Process: Weathering and Erosion
> 🔹 Factors: Wind, water, temperature changes, time

- Observation: A cliff with a flat top and steep sides, meeting a body of water.
- Explanation: This shows erosion by water. The base of the cliff is being worn away, which can lead to collapse.
- Factors Responsible:
- Wave action – constant impact of water on the base.
- Hydraulic pressure – water forces into cracks.
- Weathering – weakens rock before erosion occurs.
- Gravity – causes rockfalls once weakened.
> ✔ Process: Erosion
> 🔹 Factors: Water (waves), gravity, weathering
---
- Observation: A muddy dirt road with tire tracks and vegetation on both sides.
- Explanation: This shows erosion caused by human activity and water runoff.
- Factors Responsible:
- Vehicle traffic – compacts soil and creates channels for water flow.
- Rainwater – runs off along tire tracks, washing away soil.
- Lack of vegetation – bare soil is more vulnerable to erosion.
- Gravity – helps move soil downhill.
> ✔ Process: Erosion
> 🔹 Factors: Rainwater, vehicle movement, lack of plant cover, gravity

| Image | Process(es) Occurring | Factors Responsible |
|------|------------------------|---------------------|
| 1 | Erosion | Waves, water, time |
| 2 | Weathering | Temperature change, freeze-thaw, water |
| 3 | Weathering (biological & physical) | Plant roots, drying, sun, wind |
| 4 | Weathering & Erosion | Wind, water, temperature, time |
| 5 | Erosion | Waves, water, gravity, weathering |
| 6 | Erosion | Rain, vehicles, lack of vegetation, gravity |

- Weathering breaks rocks down in place.
- Erosion moves those broken pieces.
- Deposition is not clearly shown in any image — none depict sediments being dropped and settling (e.g., sandbars, deltas). But deposition often follows erosion.
This worksheet helps students distinguish between these three key geological processes using real-world examples.
