When the warm and cold currents meet, a dense fog is created. Give reason.
When the warm and the cold currents meet, a dense fog is created. This is because the air above the warm currents is warm and has the capacity to hold water vapour(warm air has more capacity to hold water vapour than the cold air). When this warm current meet the cold current, the air above the cold current causes the water vapour of the warm current to condense into tiny particles which form a fog.
