Question
Give an example of physical weathering and an example of chemical weathering
Answers
GPT 3.5
An example of physical weathering is freeze-thaw action. When water seeps into cracks in rocks and freezes, it expands and exerts pressure on the rocks, causing them to break apart gradually. This freeze-thaw cycle repeats, leading to the disintegration of the rock.
An example of chemical weathering is the rusting of iron. When iron is exposed to oxygen and moisture, a chemical reaction occurs which forms a reddish-brownish substance known as iron oxide or rust. This chemical reaction weakens the iron, causing it to become brittle and eventually deteriorate.
