• Sea Breeze
• During the day, the land warms up faster than
  the water.
• The warm air over the land rises,
• while the cooler air over the water sinks down
  and moves in to replace the warm air.

3

• As the warm air rises, it expands and cools.
• As it cools, it becomes more dense, so that it
  sinks back down.
• A convection current is created

• Land Breeze
• At night, dry land cools faster than water, due
  to the waters large specific heat capacity.
• Since the land cools faster than the water, the
  air above the water is now
• warmer and less dense than the air above the dry
  land.

8

• Therefore the path of the convection current is
  the opposite of the daytime current. Warmer air
  above the water is rising,
• drawing in the cooler air from the
• land.
