Question

independent practice a soil profile shows how soil varies between ____. a. adjacent regions, such as neighboring farm fields b. regions that are far apart and have different climates c. the surface and the parent material beneath it d. regions that have different types of parent material

Explanation:

A soil profile is a vertical cross - section of the soil, showing the layers (horizons) from the surface down to the parent material. Option A is about adjacent regions (like farm fields), which is more about lateral soil variation, not a profile. Option B is about regions with different climates, which is related to soil formation on a large scale, not a profile. Option D is about regions with different parent materials, again more about lateral or regional differences. Option C correctly describes what a soil profile shows: the surface (topsoil etc.) and the parent material beneath it, as a soil profile is vertical and shows the layers from surface to the underlying parent material.

Answer:

C. the surface and the parent material beneath it
