Which of the following is the best explanation for the formation of Hadley cells in the tropics, as seen in the diagram, between and latitude? A) Heat from the ocean warms the moist air at the equator and causes it to rise because of its lower density. As the air becomes cooler, it becomes less dense and sinks. B) The Sun warms the moist air at the equator and causes it to rise because of its lower density. As the warm air moves away from the equator, it cools, becomes denser, and then sinks. C) Air cools over the land at the equator and then rises as it moves north or south. D) Rising air over the equator is heated by the Sun, moves north, and then moves south to create the jet stream and trade winds.

B) The Sun warms the moist air at the equator and causes it to rise because of its lower density. As the warm air moves away from the equator, it cools, becomes denser, and then sinks.
