Question

Give two examples of the areas that receive less than 25 cm of annual rainfall.

Answer 1

Two examples of areas that receive less than 25 cm of annual rainfall are:

1. Tropical deserts are located between 15° to 30° North and South latitudes on the western margins of continents, such as:
   • The Sahara Desert in North Africa
   • The Kalahari Desert in South-West Africa
   • The Arabian Desert in Asia
   • The Atacama Desert in South America
   • The Great Australian Desert in Australia
2. Polar regions, where very low temperatures limit evaporation and precipitation, resulting in scanty rainfall.

These deserts typically receive less than 25 cm of rainfall annually, often due to dry trade winds shedding moisture on eastern margins of continents and cold ocean currents preventing rain formation.
