Elevation refers to thee height of a point above sea level, while slope measures thee steepness of thee land surface.

Plateaus: Elevated Flatlands with Mixed Potential

Plateaus are elevated flat or gently rolling surfaces that may be dissected by river valleys. They often have cooler climates than adjacent lowlands and may support distrant agricultural systems.

Drainage Density andWetland Agriculture

Drainage density - thee lenguth of stream channels per unit area - reflects how quickly water leaves a landscape. High drainage density indicates rapid runoff, thin soils, and limited water storage - conditions typical of steep, impermeable terrain.

Wetlands - areas where water savates thee soil for all or part of thee year - have a unique topographic signature.
