The cold waters surrounding Antarctica, known as the Antarctic Bottom Water, are so dense that they push against the ocean floor. The Antarctic Bottom Water causes warmer waters to rise, or upwell. Antarctic upwelling is so strong that it helps move water around the entire planet.
The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle.

2 dni temu · Antarctica, the world’s southernmost continent, is almost wholly covered by an ice sheet and is about 5.5 million square miles (14.2 million square km) in size. It is divided into East Antarctica (largely composed of a high ice-covered plateau) and West Antarctica (an archipelago of ice-covered mountainous islands).
2 dni temu · Effects of glacial erosion and deposition dominate everywhere in Antarctica, and erosional effects of running water are relatively minor. Yet, on warm summer days, rare and short-lived streams of glacial meltwater do locally exist.
27 sty 2016 · The Antarctic continent alone has a coastline of 32,000 km. It is surrounded by a massive body of water, the Southern Ocean, whose dominant circulation feature is a circumpolar current. It builds a front between 40°S and 60°S along which warmer water from more northern, temperate latitudes mixes with cold water masses from the Southern Ocean.
Physical geography. Most of Antarctica is covered in ice because of its cold climate. Antarctica has an average temperature of -30˚C but it can reach -60˚C in the coldest parts of the year. In...
