Question

Which climate conditions will cause the fastest chemical weathering of granite sandstone and shale?

Answer 1

From having worked in the tropics a little, I would say that tropical conditions can be ideal for chemical weathering of granite, sandstone and shale. A combination of the heat, and considerable water or rain in the rainy season allows the chemicals to attack the mineral grains especially the feldspars and convert them to clay. Saprolitic soils can form from such decomposition.

Answer 2

The correct answer is - tropical wet.

The tropical wet climate conditions are the ones that will enable the quickest chemical weathering of the granite, sandstone, and shale. That is due to the constant heat, high humidity, and daily rain pours.

The water from the rain, and the intense humidity caused by the heat, will interact with the rocks and will be altering their surface with the chemical properties it posses.

In a very small period of time, the rocks will start to be weathering, change their shape, and lose layers.
