Answer:
B.convection current
Explanation:
Convection current causes the movement of air between the land and ocean.
Convection is a form of heat transfer prominent in fluids, liquids and gases.
In this case, temperature and density differences plays very vital roles in moving heat.
- The surface is a good conductor of heat and the air around it heats up.
- This makes the is air less dense and it rises.
- The air above is colder and denser and it replaces the rising warm air.
- The continuous cyclic exchange sets up convection currents.
