Final answer:
The region between the equator and the South Pole is referred to as the Southern Hemisphere, which includes the Antarctic Circle and experiences opposite seasons to the Northern Hemisphere.
Step-by-step explanation:
The region between the equator and South Pole is the Southern Hemisphere.
Antarctica is located in this hemisphere and is known as Earth's southernmost continent. It encompasses the geographical South Pole and is a part of the Antarctic region. The Southern Hemisphere is characterized by the Antarctic Circle at 66.5 degrees south of the equator and is surrounded by the Southern Ocean.
Furthermore, parallels or Lines of Latitude are important to understand geographical regions. They run from 0 degrees at the equator to 90 degrees at the poles; parallels south of the equator are labeled with an 'S' to denote south latitude. This hemisphere experiences the seasons opposite to those in the Northern Hemisphere due to its position relative to the equator.
