Deserts occcur mainly due to a laack of rainfall. Well then why is there a lack of rainfall.
There are several reasons:
1. A rain shadow - this is a when a moutain range forces up moist air which causes it to rain at or neear the top of the moutain leaving dry air to move in the rain 'shadow'.
2. cold ocean current on the west coasts of many continents tend to promote desert environment because they are linked with a lack of moist air.
3. Some deserts are due to moisture just being lost due to air having to travel long distances over land.
The link between desert and dessert.
dessert, the sweets after the main meal, comes from the old french word 'desservier', which means to clear the table. This happens to often fit the description of a desert quite nicely.
