JAMB Geography 2015 Paper

Question : 8

Total: 81

Solution:

Concept:

West Africa's latitudinal extent is described by the northern and southern boundary lines that lie north of the equator.

Explanation:

West Africa sits entirely in the Northern Hemisphere.

Its southern coast begins around

4^\circ\text{N}

Its northern border extends up to about

20^\circ\text{N}

Thus, the region lies between

4^\circ\text{N}

and

20^\circ\text{N}

north of the equator.

Options that start at

2^\circ\text{N}

3^\circ\text{N}

place West Africa too far south.

Options that end at

10^\circ\text{N}

15^\circ\text{N}

cut off the northern part of the region.

Only the range from

4^\circ\text{N}

20^\circ\text{N}

fits the actual position of West Africa.

Answer:

Option A —

4^\circ\text{N}

and

20^\circ\text{N}

of the equator.
