Question

questions 9 and 10 refer to the following. a model of prevailing wind patterns around the world is shown in the diagram below. which of the following is the best explanation for the formation of hadley cells in the tropics, as seen in the diagram, between 30°n and 30°s 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.

Explanation:

Hadley cells are formed due to the heating of air at the equator. The Sun warms the moist air at the equator. As the warm air rises, it moves pole - ward. As it moves away from the equator, it cools, becomes denser, and then sinks. This is described in option B.

Answer:

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.
