Final answer:
Rocks crack and break apart more frequently in desert climates due to the large difference in day and night temperatures. Similar cracking can occur in flat regions, but not as pronounced. In mountainous regions, freezing and thawing process causes rocks to crack and break apart.
Step-by-step explanation:
Rocks crack and break apart more frequently in desert climates because of the large difference in day and night temperatures. In desert climates, the temperature can vary drastically between hot days and cold nights. This rapid change in temperature can cause rocks to expand and contract, leading to cracks and breaking apart.
On the other hand, rocks in flat regions may also crack and break apart due to the temperature difference, but the difference is not as pronounced as in desert climates.
In mountainous regions, rocks can crack and break apart due to the freezing and thawing process. When water seeps into cracks in the rocks and freezes, it expands, putting pressure on the rocks and causing them to crack.
