Chapter 13: Problem 14

What is physical weathering? Give an example.

Short Answer

Expert verified
Physical weathering is the breakdown of rocks and minerals on Earth's surface due to physical processes such as temperature changes, wind, water, ice, or the actions of organisms. An example of this is frost wedging, where water freezing and expanding within the cracks of rocks causes them to break down.

Step by step solution

01

Define Physical Weathering

Physical Weathering, also known as mechanical weathering, is the breakdown of rocks and minerals on Earth's surface due to physical processes. These processes can include temperature changes, wind, water, ice, or the actions of organisms.
02

Provide an example of Physical Weathering

Frost wedging is a great example of physical weathering. It happens when water seeps into the cracks of rocks, and when the temperature drops and the water freezes, it expands. This expansion causes the rock to fracture and crack, breaking it down over time.
