Which factors significantly affect soil formation?

The factors that significantly affect soil formation include climate, parent material, and biological activity.

Climate is crucial as it determines the temperature and moisture conditions that influence weathering processes and organic matter decomposition. For example, warmer and wetter climates accelerate chemical weathering and the breakdown of parent materials into soil.

Parent material refers to the mineral and organic material from which the soil develops. It influences the soil’s texture, mineral content, and nutrient availability, which are fundamental to soil properties and fertility.

Biological activity encompasses the effects of organisms such as plants, animals, and microorganisms on soil formation. These organisms contribute to the formation of humus through the decomposition of organic matter, enhance soil aeration and structure, and play a role in nutrient cycling.

While the other options include relevant concepts, they do not encapsulate the primary factors that have such a direct impact on the fundamental processes of soil formation like climate, parent material, and biological activity do. Exploring those other factors could provide insights into agricultural practices or land management, but they are not as foundational in the context of soil genesis.
