A desert biome is a harsh, dry, and dangerous place. A hot and dry desert receives very little rain,usually about 0-15 cm a year. Deserts are also subject to a flash flood, and that usually only happens when there is a heavy period of rainfall, or when water builds up and pours from the mountains.In a sandy desert biome, it is filled with sand dunes and small insects which burrow under the ground to escape the heat. Here is my representation of a sandy desert.
