rocks that form desert pavement.
3. _____ Glaciers take large rock material and push it forward, as the ice melts, it
leaves the rocks behind.
4. _____ The iron in a rock is turned to rust when exposed to oxygen, weakening
the rock and making it easier to break.
5. _____ Extreme temperature changes in the desert cause the rock to expand
and contract and eventually cause it to split.
Tell me if the weathering process named below is Physical weathering or
