Explanation:

All the given factors are responsible for the aridity of deserts.
o Interior location in the continent or continentality - for example Gobi desert. It lies in the interiors
of China. Moisture bearing wind shed their moisture before reaching to such regions.
o Cold ocean currents reduce the humidity in the atmosphere. Example Atacama Desert under the
influence of Peru Current.
o Leeward location - example Patagonian Desert on the leeward side of Andes Mountains
o Location along horse latitudes (around 30 Degrees N & S). These are regions of descending air thus
experience high pressure which is not a favorable condition for rainfall.
