The Arctic Plain is a vast, flat expanse of land located in the northernmost regions of the world. It is characterized by its cold temperatures and lack of vegetation. The term 'Arctic Plain' encompasses three distinct geographical features: the TUNDRA (6 letters), Berg (4 letters), and POLAR (5 letters). The TUNDRA is a treeless plain that is covered with snow and ice for most of the year. The Berg is a large mass of ice that is found in the Arctic Ocean. Finally, the POLAR region is an area of extreme cold and darkness that is located near the North Pole. Together, these three features make up the Arctic Plain.
