Minecraft wiki entry for Badlands, associated text: Badlands biomes feature large mounds of terracotta, in layers of various colors; specifically, red, orange, yellow, white, light gray, brown, and regular terracotta may all naturally generate. These mounds rise up from a layer of red sand, and are about 10-15 blocks thick, giving way to typical stone variants below that. Cactus and dead bushes generate frequently across the landscape, similarly to deserts. Badlands biomes generate in warm regions and in areas with low erosion, which means that they usually generate in areas with plateaus and sometimes even mountain peaks.
