Question | Answer |
How much rainfall can an area have to be called a desert? | 250mm per year |
Where are most deserts located? | Around the equator- 20° and 35° north and south of the equator. |
List one reason why a desert could be hot. | The sun is directly over head, meaning a constant level of sunlight but also at a high concentration meaning it will be hotter |
Suggest another reason why a desert may be hot. | No cloud cover means no shade from the un in the day. |
Suggest two reasons why deserts may be dry. | The global circulation system means moist air rises at the equator where there is a lot of rain, therefore the now dry air descends on the location of deserts. The rain shadow effect causes relief rainfall over mountains and so no rain for deserts. |
Why will deserts be hotter in the day than at night? | In the day the suns rays are absorbed into the ground but the heat quickly disperses at night because there is no cloud cover. |
What causes relief rainfall? | Hot air mixing with cool air higher in the atmosphere (usually over mountains) |
