Physical weathering involves the breakdown of rocks and minerals without changing their chemical composition. One common example is freeze-thaw weathering, where water seeps into cracks in rocks, freezes, expands, and eventually causes the rock to break apart. Another example is exfoliation, where outer layers of rocks peel off due to changes in temperature and pressure.
An example of a non-physical weathering process is chemical weathering, where rocks are broken down by chemical reactions rather than physical forces like temperature changes or abrasion.
The cracking of rocks due to freezing and thawing of water is an example of physical weathering. As water seeps into cracks in rocks and freezes, it expands, causing the rocks to break apart over time.
No, splits in a rock due to tree roots is an example of physical weathering or biological weathering, not chemical weathering. Chemical weathering involves the breakdown of rocks through chemical processes like dissolution, oxidation, or hydrolysis.
Some synonyms for physical weathering are mechanical weathering and disintegration.
It is an example of mechanical or more specifically biomechanical weathering.
