The map shows that different regions of the world have different soil types.

Which of the following is most likely true?
A.
The soil type of a region depends only on the distance of that region from the ocean.
B.
The soil type of a region depends on the type of geologic processes that occur there and the rate at which they occur.
C.
The geologic processes that result in soil occur at the same time and at the same rate in every region of the world.
D.
All types of vegetation are able to grow equally well in all soil types around the world.

Answer 1

The most likely true statement is:

B. The soil type of a region depends on the type of geologic processes that occur there and the rate at which they occur.

This is because soil formation is influenced by various factors, including the geological processes that shape the land, climate, vegetation, and topography, which all vary from one region to another.

The other options are not accurate: A. Soil type is influenced by many factors, not just proximity to the ocean. C. Geologic processes differ widely across regions and do not occur at the same rate. D. Different soil types support different types of vegetation, so not all vegetation can grow well in all soil types.
