Convection and Weather

If differences in air pressure produce winds, what can you conclude about temperature and air pressure based on the figure?

• As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind

• Warm air is denser than cold air is, creating an area of high pressure the produces wind.

• Winds flow from areas of low pressure to areas high pressure when temperature is warmer

• Air pressure decreases at night because temperature is lower, producing land and sea breezes

Some dye in a beaker of water is gently heated. Why are the streaks of dye seen in the water?

• The hot dye is a better conductor than the cool water.

• The hot dye is a better convector than the cool water.

• The hot water is less dense than the cool water.

• The hot water is denser than the cool water.

What causes convection current in the Earth?

• The uneven heating on each layer inside the Earth.

• The crusts outer layer.

• The temperatures we feel outside.

At the seashore late in the afternoon on a hot day, a person often feels a strong breeze coming from the ocean because...

• the pounding waves generate air currents

• warm air over the ocean rushes in to replace the cool air that rises over the land

• the heavy, cool air over the ocean rushes in to replace the warm air that rises over the land

• there are no clouds to block the wind coming in from the ocean

Tim said that Chicago is most likely to experience rainy weather. Jennifer thinks that Dallas is most likely to experience rainy weather. Which student is correct?

• Tim because Chicago is the closest to a low pressure system and they produce precipitation.

• Jennifer because high pressure systems produce precipitation

• Both students are correct because all systems produce precipitation

• Neither of the students are correct because the cities are not close enough to the system.
