Question 3 of 13 • FL-2003310-Physical Science
The diagram shows how air circulation forms a sea breeze on a warm day.Which best describes what is happening in the diagram?
Answer
A
At point 1, the air in the convection current is warmer and denser than at point 3 because its molecules contain more kinetic energy.B
At point 2, the air absorbs thermal energy from the surrounding air, which causes it to become heavier and sink.C
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.D
At point 4, thermal energy from warm air over the land is transferred upward toward cooler areas of the atmosphere.
