Question

In each hemisphere for which latitude the length of the circle is half the length of the Equator?

Options

• 30°

• 45°

• 60°

• 90°

Answer 1

60°

Explanation:

At 60° latitude (either north or south), the length of the circle of latitude is half the length of the Equator. This is because the Earth's radius decreases as you move away from the Equator towards the poles, and the circumference of the Earth at 60° latitude is half of the circumference at the Equator.
