Among the following environmental factors, which does not have a long-term impact on the composition of a region's soil? a. kinds of crops grown b. types of fungi present c. topography of the landscape d. variety of species of mammals e. number of freezes occurring annually

Topography of the landscape does not have a long-term impact on the composition of a region's soil.

Explanation:

Various factors control the amount of region's soil that can be bound, including climate, raw material, age and soil structure, topography, vegetation type, and soil reservoir composition. The annual rainfall and seasonal species temperature contribute to the increased diversity of soil species in the region.

Topography has a big impact on Earth's evolution. The slope is usually smooth due to erosive losses. Soils of mountain peaks are usually deep, but brighter due to leaching losses. So the topography of landscape does not have a long-term impact on the composition of a region's soil when compared to other factors.
