The source region of a maritime polar air mass is typically a cold, moist maritime region near the poles, such as the North Atlantic or North Pacific Ocean. As the air mass moves away from this region, it can bring cool, damp weather conditions to areas it affects.

in the polar regions
The south polar region's elevation is higher than the north polar region, because the south polar region is a continent and the north polar region is ocean.
yes oxygen is non polar .
the north of Siberia is in the polar region.
The opposite of a tropical region is a polar region.
Propane itself is non polar, but the presence of the ketone group (C=O) in propanone makes it a polar molecule (oxygen has partial -ve charge). As propanone is a small molecule it can be soluble in water, which itself is polar.
The characteristics of an air mass are heavily influenced by its source region. The temperature, humidity, and stability of an air mass are reflective of the conditions prevalent in its source region. For example, an air mass originating from a tropical ocean region will be warm, moist, and unstable, while an air mass from a polar continental region will be cold, dry, and stable.
The polar region around the North Pole is called the Arctic and the polar region around the South Pole is called the Antarctic Region
The Arctic and antarctic are the two polar ice regions. Iceland does exist, but is not considered to be a polar region.
