Arrange the regions of Africa in order of how much rainfall they receive, from the least to the most rainfall received in an average year.

Answer 1

The regions of Africa can be generally arranged based on average annual rainfall from least to most as follows:

1. Sahara Desert - This vast desert region receives the least rainfall, often less than 250 mm (10 inches) annually.

2. Kalahari Desert - Located in southern Africa, this semi-arid region receives slightly more rainfall than the Sahara, averaging about 250-500 mm (10-20 inches) per year.

3. Namib Desert - Similar to the Kalahari in terms of low rainfall, averaging between 100-300 mm (4-12 inches) annually in different areas, with coastal regions being drier.

4. Sahel - This semi-arid region located south of the Sahara receives 250-600 mm (10-24 inches) of rainfall per year during the brief wet season.

5. East African Highlands - Regions like Ethiopia and parts of Kenya receive varied rainfall, generally averaging around 600-800 mm (24-32 inches) annually.

6. Central Africa (Congo Basin) - This area gets significantly more rainfall, with averages ranging from 1,200 to 2,000 mm (47-79 inches) annually.

7. West Africa (tropical regions) - This region typically receives about 1,000-1,500 mm (39-59 inches) of rainfall per year, depending on specific areas and proximity to the ocean.

8. Southern Africa (tropical areas) - Some areas receive significant rain, especially during the summer months, averaging from 700-1,200 mm (28-47 inches) per year, particularly near the coasts.

9. East Africa (Lakes and coastal regions) - Areas around Lake Victoria and the coastal regions often average above 1,200 mm (47 inches) annually, due to their tropical climate and humidity.

This arrangement is a general representation and can vary within specific subregions of Africa due to diverse local climates and geographical features.
