Continental climate is not a major climate zone, as it is a combination of temperate and polar climates.

Air pressure differences, caused by variations in temperature and density, drive the movement of air masses and create weather patterns.

Nitrogen is not a greenhouse gas, as it does not absorb and trap heat in the atmosphere.

Climate refers to the long-term average of weather conditions, including temperature, precipitation, and wind patterns, in a particular area.

The Antarctic Ice Sheet is the largest ice sheet on Earth, covering an area of approximately 14 million square kilometers.

Glacial flow refers to the movement of glaciers and ice sheets due to the deformation of ice under its own weight and the force of gravity.

Hail is not a type of precipitation, as it is a form of frozen rain that forms when raindrops freeze inside a thunderstorm cloud.

Ablation refers to the process by which glaciers and ice sheets melt, either through surface melting or sublimation.

Antarctica is the coldest region on Earth, with temperatures reaching as low as -94°C (-137°F).

Calving refers to the process by which icebergs break off from glaciers and ice sheets, typically due to the melting of the ice at the base of the glacier.

Nimbus is not a type of cloud, but rather a cloud classification that includes clouds that produce precipitation.

Accumulation refers to the process by which snow accumulates on the surface of a glacier or ice sheet, increasing its mass.

Piedmont glacier is not a type of glacier, but rather a type of ice sheet that forms at the base of mountains.

Glacial erosion refers to the process by which glaciers and ice sheets erode the underlying rock and soil through abrasion, plucking, and quarrying.

Icebergs are not a type of sea ice, as they are formed from glaciers and ice sheets rather than from seawater.
