Northern hemisphere. Satellite image of the northern hemisphere of the Earth. The North Pole is at centre, surrounded by the Arctic ice pack (white). Water is blue, vegetation is green and arid areas are brown. At lower right, the massive land mass of Eurasia, the largest continent on the Earth, dominates the hemisphere. It consists of Europe (lower centre) and Asia (centre right to lower right). North America (upper left) lies between the Atlantic Ocean (lower left) and the vast Pacific Ocean (upper left to far right). Northern Africa is just visible at bottom centre.
