If rains occur, they are recorded as an average of 250 mm per day. So deserts always remain dry and have a clear sky. We find only sand in Desert because they remain very high temperature over billions of years leading to weathering phenomena from huge

The newest and largest national desert preserve is located in the rain shadow of southern California's coastal range where, if plants and animals are lucky, they'll get five inches of rainfall annually. It's also one of the most photographed deserts in the world and the home of the world's largest Joshua tree forest with 1.6 million-acres protected in Mojave National Preserve.
