Davis's proposed landscape-development states. The morphology shown is not actually time-indicative. For example, A could be a gully system in soft sediment or a canyon such as the Royal Gorge in Colorado, which is millions of years old. The ridge-ravine topography of B would normally develop under humid conditions, but the river meandering on alluvium indicates a prior or extraneous non-humid aggrading mechanism. The riverine plain of C implies a complex history of planation and aggradation in a current fluvial mode.
Plains are defined as relatively level areas of the Earth’s surface characterized by gentle slopes and minimal local relief. These landforms have historically become significant hubs for human activity due to several key geological and topographical advantages:1
- Agriculture: The flat surfaces of plains are easily cultivated and frequently feature highly productive soils, such as the nutrient-rich mollisols found in regions like the Great Plains.12
- Transportation: Because plains possess low relief, they present few physical obstacles to the development of land transportation networks.1
- Navigation: Rivers that traverse these level landscapes are generally much easier to navigate compared to those found in rugged or mountainous terrain, facilitating trade and movement.1
Consequently, these favorable conditions have made plains the preferred sites for major centers of population, industry, and commerce.1
