Weathering is more efficient than erosion in the bare slopes, Preface 121 nevertheless, the more frequent recurrence of frost and the lower temperatures reached in the north-facing slopes prevent vegetation recovering and maintain badlands active. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density. In contrast to the badlands farther north, which are shades of light brown, these older beds are darker, tending to be purple and gray. Geology of the Badlands.

Features form by weathering along vertical joints cutting horizontal strata: slot canyons, fins, and arches. Badlands National Park, South Dakota . Pine Ridge Indian Reservation-Wikipedia. Northeastern Kansas fell under ice during at least two glacial invasions in that epoch, and its landscape reflects the power of the enormous ice bodies to erode and reshape the terrain. 1 Sinhati badland (d) is located 4 km NW of Bishnupur town (c) of Bankura district (b) of West Bengal (a). The gullies extend from main rivers back to tablelands about 150 m (500 feet) and higher. 1. Weathering. Major kinds of Deserts The distribution of arid regions or deserts is determined by the climate and topography. Because the rocks are not uniform in character, differences in erosion result in stair-step profiles.
