Which physical feature’s formation is most closely related to the soil building process?

Hello. You did not provide answer options. However, one of the physical characteristics of the Earth's crust most closely related to soil construction is the existence of minerals and assimilable nutrients in the crust.

Explanation:

The earth's crust has many physical characteristics, one of which is to be an environment where plants can establish themselves and assimilate nutrients. This characteristic is directly related to the formation of the soil. This is because during weathering, which is the process where a rock is fragmented to create the soil, the rock has minerals grouped in its composition. As the rock breaks down these minerals it leaves the rock and incorporates the fragments that will form the soil. These are minerals that will be the assimilable nutrients for plants.

the answer would be b).
