The South Pole is colder because of its higher altitude and being on land. Here's why:
Higher Altitude: The South Pole is located on the continent of Antarctica, which has an average elevation of about 7,545 feet (2,300 meters) above sea level. Higher altitudes generally result in colder temperatures because the air at higher elevations is thinner and contains less heat-absorbing moisture.
Being on Land: Unlike the North Pole, which is located in the Arctic Ocean and covered by sea ice, the South Pole is situated on a high plateau of land. Landmasses tend to get colder than bodies of water because land heats up and cools down more quickly than water. Additionally, the land at the South Pole is covered by a thick ice sheet, which further contributes to its extreme cold.
The combination of high altitude and being on a landmass makes the South Pole significantly colder than the North Pole. In fact, the South Pole is one of the coldest places on Earth, with average temperatures well below freezing throughout the year.
