Cold ocean currents on the movement of icebergs

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. Cold ocean current flows from poles to the equator. In this process, there are chances that iceberg from the polar areas gets carried along the current. This, in turn, poses threat to marine routes where frequent movement of ships takes place.
