Question

Deserts such as the Sahara are generally found between 20 and 30 latitudes in the western parts of the continents. This is because these regions ________________.

• A. have off-shore winds throughout the year
• B. have warm off-shore currents
• C. lie in the belt of the doldrums
• D. are very hot throughout the year

Answer 1

The correct option is A have off-shore winds throughout the year

• The areas between 20 and 30 latitudes on western margins of continents are the regions of descending air(high pressure and dry weather). Because of this the air gets compressed and warms as it descends and thus the moisture keeps decreasing. Thus these regions have off-shore winds throughout the year.
