* Parent material: The bedrock or sediment that soil develops from directly influences the soil's mineral composition and texture.

* Climate: Temperature, precipitation, and humidity all play a role in weathering, decomposition, and the movement of soil materials.

* Topography: Slope, elevation, and aspect influence the amount of sunlight, drainage, and erosion, all affecting soil development.

* Animals in the area: Animals burrow, dig, and contribute organic matter to soil, influencing its structure and fertility.

* Organisms: Bacteria, fungi, and other microorganisms are vital for decomposition, nutrient cycling, and soil structure.

Time is a crucial factor in soil formation. It takes a long time for bedrock to break down into soil. The processes of weathering, decomposition, and nutrient cycling all occur over extended periods, leading to the gradual development of mature soil profiles.

Think of soil formation as a slow and steady process. Time is an essential ingredient, just like the other factors mentioned.
