A) they have no effect on air temperature over land on the coast is False
Step-by-step explanation:
- warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
- the temperature over the land increases when warm ocean currents heat the air above the ocean.
- the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
- so, ocean currents play a major role in regulating the air temperature over land on the coastal region.
