Answer:
D. A young soil in an arid climate will be thinner than an old soil in a temperate climate.
Step-by-step explanation:
Arid climate is common with deserts. Arid climate is characterized with very little rainfall while the temperate climate has moderate rainfall.
Arid climate has soils with sparse vegetation while temperature climate has soils with lots of vegetation.
The composition of soil is dependent on the vegetative matter and amount of moisture in it. The temperate climate has soils with more vegetative matter and moisture compared to soils in arid climates. This validates a young soil in an arid climate being thinner than an old soil in a temperate climate.
