At the coast on a summer day, the land is hotter than the ocean. Warm air over the land rises and is replaced by cooler air, causing a sea breeze. At night, the land cools quickly and the ocean is now warmer than the land. What will happen next? a) Winds will stop blowing as the convection current ceases to flow.

b) The convection current will reverse direction, reversing the winds.

c) Winds will increase as the two convection currents overlap.

d) The convection current will move seaward, reversing the winds.
