TermDefinition
Deserts a dry arid area of land with less than 250ml of precipitation
Cold desert are permanently frozen with long, cold winters and short, mild summers
Arid is a land with under 250ml or no rain and to dry, barren to support vegetation
The rain shadow effect An area having relatively little precipitation due to the effect of a topographic barrier, especially a mountain range, that causes the prevailing winds to lose their moisture on the windward side, causing the leeward side to be dry.
Semi-arid climates tend to support short or scrubby vegetation, with semi-arid areas usually dominated by either grasses or shrubs. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined.
desertification is where the desert speads becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities
