Final answer:
Gravity has a minimal influence on the topographic development of flat lands, as it does not contribute as much to soil erosion and runoff compared to steep slopes, resulting in more developed soil.
Step-by-step explanation:
Where the land is flat, gravity exerts a minimal influence on topographic development. In flat regions, processes such as soil erosion, runoff, and water infiltration are less affected by gravity compared to areas with steep slopes. Flatter areas do not experience as much soil erosion because there is less runoff of rainwater, which allows for more water infiltration and consequently, more thorough soil development. However, in regions with steep slopes, gravity significantly influences these processes, leading to increased soil erosion and less mature soil profiles. Additionally, topography can have microclimatic effects, showing variations in climate within small geographical areas, which are inherently less dramatic in flat terrains.
