What geographic latitude defines the "south polar" region?

The "south polar" region is defined as being south of 60 degrees South latitude. This classification is crucial in various contexts, including climatology, ecology, and aviation, as it delineates the extreme southern parts of the Earth that experience unique weather patterns and ecosystems.

Geographically, areas south of 60 degrees South latitude are part of the Antarctic region, where conditions are typically much colder and harsher than further north. This definition is often used in discussions about environmental policies, Antarctic treaties, and scientific research, emphasizing the distinct characteristics of the polar climate and the habitats found there.

While the other latitude options indicate different geographic regions, they don't fall within the commonly accepted definition of "south polar." For example, areas south of 68 degrees South or 78 degrees South may still be considered part of the broader Antarctic territory but are not specifically classified as the "south polar" region. Thus, the choice of south of 60 degrees South is the most accurate in defining the south polar region.
