2.4.3.1 Badlands

A badland is a large- or small-scale region characterised by intricate and sharp erosional topography. The divides are sharp, and the slopes are incised with rivulose ravines, furrows, and rills. Badlands most oftem develop in soft sedimentary rocks (like shale), but they can also form in other locales, such as decomposed igneous rocks and loess.

Badlands are usually found in arid to semi-arid climates where rainfall is concentrated in infrequent but strong downpours. They often develop in the form of terraces and have little to no vegetative cover.

Hoodoo is a term used to describe fantastic and intricate erosional topography that has been strongly influenced by jointing.
