What is a hemisphere?

What is a hemisphere?

• A. Half of the Earth
• B. A line of latitude
• C. A type of map projection
• D. A time zone

Answer: (A)

A hemisphere is half of the Earth. The globe is split into halves by a great circle, most commonly the equator, which creates the Northern and Southern Hemispheres, and it can also be described as halves divided by the prime meridian and its opposite line to form Eastern and Western Hemispheres. This concept helps explain why different places experience different seasons, daylight hours, and weather patterns. A line of latitude is a circle around the Earth that measures how far north or south you are from the equator, but it isn’t itself a half of the Earth. A map projection is simply a way to represent the curved surface of the Earth on a flat map. A time zone is a region with a standard time, not a half of the globe.
