High-Pressure region.
The South Pole is a low pressure region. Cold temperature areas tend to be low pressure while tropical regions are commonly high pressure.
The South Pole can be considered a low pressure region. Much like the North Pole, the South Pole is largely affected by a polar vortex featuring an area of low pressure.

low
you would expect it to have high pressure
Global winds also occur because large high- and low-pressure zones alternate from the North Pole to the South Pole about every 30° latitude (north-south location). Both poles have high-pressure air masses (cold, dry, high pressure) and the air above the equator is a low-pressure zone (hot, moist, low pressure). Because high pressure always invades low pressure, the resulting winds-where the high- and low-pressure zones meet-are pretty reliable. They are known as the polar easterlies (at 60° latitude north and south); the westerlies or prevailing winds (at 30° latitude north and south); and the tropical easterlies or trade winds (at the equator, 0° latitude). I hope this helps your question! :)
due to gravity
The elevation of the South Pole is more than 9,300 feet above sea level.
High. From Wikipedia: "[The South Pole] sits atop a featureless, windswept, icy plateau at an altitude of 2,835 meters (9,306 ft), about 1,300 km (800 mi) from the nearest open sea at the Bay of Whales. The ice is estimated to be about 2,700 meters (9,000 ft) thick at the Pole, so the land surface under the ice sheet is actually near [or lower] than sea level."
A fluid will move from high pressure to low pressure.
Paleomagnetism refers to the strength and orientation of the earth's magnetic field at some remote past time. Magnetic field reversals are recorded in deep ocean bottom materials which show that at some ancient times the earth's magnetic poles have reversed, north pole becoming south pole and south pole becoming north pole.
