Final answer:
Hot and humid regions and hot and rainy regions are most likely to experience chemical weathering due to the combination of high temperatures and abundant moisture.
Step-by-step explanation:
Chemical weathering is a process that breaks down existing Earth materials through chemical reactions. Two locations that are most likely to experience chemical weathering are hot and humid regions and hot and rainy regions. In these regions, high temperatures and abundant moisture create conditions that promote chemical reactions, leading to the breakdown of rocks and minerals.
For example, in hot and humid regions, the combination of heat and moisture accelerates chemical weathering. The high temperatures increase the rate of chemical reactions, while the abundance of moisture provides a medium for these reactions to occur. This can lead to the dissolution and decomposition of rocks and minerals, resulting in the formation of new compounds.
