Question

The diagram shows how air circulation forms a sea breeze on a warm day.

A beach meets the sea in the middle of the image with a blue sky above containing a bright sun. On top above the water is A pair of arrows changing from red to blue pointing right toward the sea labeled 1 Return Flow. Then a blue arrow points down over the sea labeled 2 Cool. Then a pair of arrows going from blue to red point left labeled 3 Sea Breeze. Then a red arrow points up over the sand labeled 4 Warm.
Which best describes what is happening in the diagram?

At point 1, the air in the convection current is warmer and denser than at point 3 because its molecules contain more kinetic energy.
At point 2, the air absorbs thermal energy from the surrounding air, which causes it to become heavier and sink.
At point 3, the air in the convection current is cooler and lighter than the air in other parts of the current, so it is preparing to rise.
At point 4, thermal energy from warm air over the land is transferred upward toward cooler areas of the atmosphere.

Answer 1

Answer: The fourth statement.

Reason: At point 4 warm air over the land rises and transfers thermal energy upward into cooler parts of the atmosphere (convection). The other options are incorrect (1 wrongly says warmer air is denser, 2 says cooling causes absorption of heat, 3 says cool air is lighter and will rise).
