Question

In which of the following locations would chemical weathering happen most quickly?

Amazon rainforest
Sahara desert
North Pole
Great Plains

Answer 1

Chemical weathering occurs mostly in high temperature regions because it speeds up chemical reactions.

Answer 2

In addition, the high water atmospheric content (humidity) of the rainforest will have an impact on material that can be oxidized (e.g. metal will rust). But in the desert, there is high UV radiation exposure that will have an effect on organic matter.

Answer 3

Furthermore, in the rainforest, plants are able to disintegrate the rocks chemically by chelation, where they release acids to weaken to rock structures.
