Physical weathering is the breaking down of rocks and minerals through physical processes, without changing their composition. Examples of physical weathering include erosion, freeze-thaw weathering, exfoliation, and abrasion. Erosion is the removal of weathered material by wind, water, or ice. Freeze-thaw weathering occurs when water in cracks freezes and expands, breaking apart the rock. Exfoliation is the flaking off of thin layers of rock from the surface. Abrasion is the wearing away of rock by friction from other rocks or particles.

Physical weathering is the process by which rocks and minerals are broken down into smaller pieces. This can be caused by a variety of factors, including:
- Temperature changes: When rocks are heated, they expand. When they cool, they contract. This can cause the rocks to crack and break apart.
- Freezing and thawing: Water can seep into the cracks in rocks. When the water freezes, it expands. This can cause the rocks to crack and break apart.
- Water: Water can also cause physical weathering through abrasion. This is the process by which rocks are worn down by the movement of water.
- Wind: Wind can also cause physical weathering through abrasion. This is the process by which rocks are worn down by the movement of wind.
Here are some examples of physical weathering clip art:
- Rocks that have been cracked and broken apart by temperature changes
- Rocks that have been broken apart by freezing and thawing
- Rocks that have been worn down by abrasion
- Sand dunes
- Loess
The following table provides a summary of the different types of physical weathering and the examples of clip art that can be used to illustrate each type:
| Type of Physical Weathering | Examples of Clip Art |
|---|---|
| Temperature changes | Rocks that have been cracked and broken apart |
| Freezing and thawing | Rocks that have been broken apart |
| Water | Rocks that have been worn down by abrasion |
| Wind | Sand dunes, loess |
Question 1:
What is physical weathering?
Answer:
Physical weathering is the process of breaking down rocks and minerals into smaller pieces due to physical forces, without altering their chemical composition.
Question 2:
How does physical weathering occur?
Answer:
Physical weathering occurs through various mechanisms, including temperature changes, frost wedging, abrasion, and pressure release.
Question 3:
What are the different types of physical weathering?
Answer:
The different types of physical weathering include thermal expansion and contraction, freeze-thaw action, exfoliation, and pressure release.
