why is antarctica the coldest
Antarctica has its features mainly due to its location at the South Pole. The South Pole tends to get significantly less sunlight than other places, this is similar to the North pole too. Less sunlight means it gets cold. In addition the permanent ice cap reflects a large amount of sunlight. Also Antarctica is on average the highest continent and so temperature decreases with altitude. The Southern ocean is somewhat colder than the northern oceans also maintaining cooler temperatures. This shows how high Antarctica is. Purple is sea level pink is about 4000metres.
