Tara said that the heavy fog in the seaside of Newfoundland is caused by the meeting of two ocean currents — the cold Labrador current and the warm Gulf Stream. Tara explained to them that when the warm, moist air of the Gulf Stream meets the cold air from the Labrador Current, the moisture in the warm air condenses rapidly, forming thick fog.
Due to the rich fishing grounds created by the mixing of these currents, the main occupation of the people in Newfoundland is fishing.
