Answer the following questions:

Why do the ports in the eastern coast of Canada freeze in winter?

Ocean currents are the horizontal continuous flow of a mass of water from one place to another. They are of 2 types – warm and cold ocean current. Ocean currents flowing along the coastline have an impact on its climate. Labrador is cold oceanic current originating in arctic ocean and flowing south along the coast of Labrador, Canada. Thus, these waters are cold and tend to freeze up the ports early in the winter.
