Consider the following prominent mountain ranges and highlands of the African continent:

1. Ethiopian Highlands
2. Atlas Mountains
3. Drakensberg Mountains
4. Ahaggar Mountains

Which of the following represents the correct sequence of these physical features from North to South?

  1. 2 – 4 – 1 – 3Answer
  2. B
    4 – 2 – 1 – 3
  3. C
    2 – 1 – 4 – 3
  4. D
    2 – 4 – 3 – 1

Answer

The correct sequence of the given African mountain ranges and highlands from North to South is 2 – 4 – 1 – 3 (Atlas Mountains → Ahaggar Mountains → Ethiopian Highlands → Drakensberg Mountains).
The correct sequence from North to South is 2 – 4 – 1 – 3. The Atlas Mountains span Morocco, Algeria, and Tunisia in northwestern Africa at approximately 31° N latitude. Moving southward into the Sahara desert, the Ahaggar (Hoggar) Mountains lie around 23° N. Further south in the Horn of Africa, the Ethiopian Highlands lie between 5° N and 15° N (centered around ~9° N). Finally, the Drakensberg Mountains form the main mountain range of Southern Africa, extending around 29° S latitude.

Step-by-Step Solution

1
Determine the approximate latitudinal position of each mountain range or highland.
Atlas Mountains (~31° N), Ahaggar Mountains (~23° N), Ethiopian Highlands (~9° N), and Drakensberg Mountains (~29° S).
Establishing absolute or relative latitudes is necessary for accurate North-to-South ordering.
2
Arrange the latitudinal positions from northernmost to southernmost.
31° N (Atlas) > 23° N (Ahaggar) > 9° N (Ethiopian) > 29° S (Drakensberg).
A North-to-South ordering requires sorting latitudes in descending order from the Northern Hemisphere to the Southern Hemisphere.
3
Match the ordered features with their corresponding numbers.
2 (Atlas) – 4 (Ahaggar) – 1 (Ethiopian) – 3 (Drakensberg).
Correlates the derived geographic sequence with the given list index.
