Step-by-step explanation:
Canada usually experiences various air masses due to its diverse geography and large landmass.
One important air mass is the maritime air mass, which originates from the Pacific Ocean and brings moist and mild temperatures to the west coast of Canada. This air mass is responsible for the high precipitation levels in that region.
Another significant air mass is the continental arctic air mass, which originates from the Arctic regions. It brings extremely cold and dry conditions to northern Canada, including the region of Nunavut.
