Heat Transfer and Wind

Which of these MOST likely causes wind to blow on Earth?

• Warm air rises and cool air falls toward Earth’s surface.

• The gravity of Earth and the Moon push and pull the air.

• Earth spins quickly, causing air to blow around.

• Ocean waves push air onto the shore and across Earth's surface.

Which of these BEST explains the cause of convection currents in Earth’s atmosphere?

• Sunlight is more concentrated in some places on Earth than others.

• Heat from Earth’s core heats the land only at the equator.

• The light and heat reflected from the Moon varies as the Moon changes phases.

• Glaciers moving away from the poles cool Earth unevenly.

How does the egg get inside the bottle?

• It is pushed by the air pressure outside the bottle.

• It expands and falls into the bottle.

• It contracts and falls into the bottle.

• It is pushed by the air pressure inside the bottle.

Why does warm air rise and cold air sink?

• Because cold air is less dense than warm air.

• Because warm air has high pressure.

When air near the ground is warmed by sunlight, which of the following occur?

• The warm air loses its ability to hold water and precipitates.

• The warm air evaporates into the cooler air.

• The warm air expands and rises, resulting in convection.

• The warm air radiates and becomes cool again.
