We live on a rocky world. Its surface supports our weight and allows us to move over, across, and around it. Geological processes, obligated by the universal laws of physics, wrench and thrash on a planetary scale to shape, destroy, and remake this surface and its constituent metals and minerals into irregular forms through great gravity, pressure, and heat. Other rocky worlds, neighbors though still alien, have, too, been molded by processes leading to uneven and unique topographical features, fashioned with familiar yet still strange landscapes. Sharing largely the same ingredients, equipped with wind whipped atmospheres and common elements forged from the same fire, our badlands are not unlike their badlands. When we understand the barren parts of our world, we understand, at least in part, a universal desert.
