Land Features

In deserts sand covers 205 of the world’s deserts, most sheets of sand is in sand sheets or sand seas. Underground channels carry water from nearby mountains. If desert channels weren’t covered they would dry up quickly form the hot temperatures. About one third of earth’s landmass is desert or semi desert. These features have certain features that aren’t found in more humid environments. These features are created by wind and water erosion. Desert areas like this, usually have internal drainage.
