The Arctic is the area around the North Pole and Antarctica is the continent at the South Pole. The Arctic is not actually land but a combination of ice and water, by contrast, the Antarctic is a continent and landmass covered in ice.

The Arctic is in the North and Antarctica is in the South. They are both at the Earth's poles but the Arctic is made up of solely ice and is just a collection of large ice caps. Antarctica is actually a continent with ice and solid land too.

The biggest difference is that the Arctic region is essentially a frozen ocean surrounded by continents. Antarctica is a frozen continent surrounded by an ocean.
