The term 'Arctic Masses' refers to two distinct types of landforms found in the Arctic region. The first is 'Bergs, ' which are large masses of ice that have broken off from glaciers and icebergs. The second is 'Snowpacks, ' which are layers of snow that accumulate over time and form a thick, solid layer of ice. Both of these landforms are important components of the Arctic environment, providing habitats for wildlife and helping to regulate the climate.
