Question

b the imaginary line drawn around earth at zero degrees longitude that divides earth into eastern and western hemispheres
c the imaginary line drawn around earth at ninety degrees latitude that divides earth into eastern and western hemicnherec

Explanation:

To determine the correct definition of the equator, we analyze each option:

• Option A: The equator is an imaginary line at 0° latitude, dividing the Earth into Northern and Southern Hemispheres. This matches the scientific definition.
• Option B: The line at 0° longitude is the Prime Meridian, which divides the Earth into Eastern and Western Hemispheres, not the equator.
• Option C: A latitude of 90° refers to the poles (North or South Pole), not the equator, and the description of dividing into Eastern and Western Hemispheres is incorrect.

Answer:

A. the imaginary line drawn around Earth at zero degrees latitude that divides Earth into northern and southern hemispheres
