The Southern Hemisphere is one of the two halves of the Earth, located south of the equator. It includes parts of several continents, such as South America, Africa, and Australia, as well as numerous islands and oceanic regions. The Southern Hemisphere experiences opposite seasons compared to the Northern Hemisphere, meaning that when it is summer in the north, it is winter in the south. This hemisphere is home to unique geographical features and ecosystems, including the Amazon Rainforest and the Great Barrier Reef. It also contains the Antarctic Circle, which is known for its extreme cold and ice-covered landscapes. The Southern Hemisphere is rich in biodiversity, with many species found nowhere else on Earth.
