What causes wind?

• uneven heating of Earth's surface.

• warm air sinking while cold air rises

• Differences in longitude

• Shock waves from clouds

Rian and Jane decide to conduct an investigation using a balloon model of Earth. Rian blows up the balloon and draws a line around the middle to represent the Equator. Then she spins the balloon while Jane tries to draw a straight line. They make a diagram in their notebook to show their results. Which of these effects did their model show?

• sea breezes

• Coriolis effect

• land breeze

• air pressure

Which of the following best describes how the circulation patterns in Earth's atmosphere would be different without the Coriolis effect?

• No monsoon rains would fall in India

• There would be only two convection cells, instead of six.

• Winds would blow directly north and south, never east and west.

• The Hadley cells would cause air at the equator to sink instead of rise.

How do jet streams influence the weather?

• by creating clouds.

• by moving weather from one area to another very quickly

• by drying out the atmosphere

• by increasing moisture in the atmosphere.
