Questions:
1) For this question, please refer to the image at
right. In humid tropical climates, where much
rain falls and temperatures are high, chemical
weathering causes thick soils to develop
rapidly. Dense vegetation in humid, warm
climates continuously adds organic material
to the topsoil. However, heavy rains –
common in tropical climates – cause a lot of
leaching of that topsoil. As a result, the A
horizon in tropical climates is typically thin, as
shown in the figure.
What is required for chemical weathering to
occur? In which climate is the rate of chemical
weathering the greatest?
What soil horizon would collect the material leached from the A horizon?
