Wind is NOT caused by

• convection currents

• differences in air pressure

• the continents shifting on Earth

• warm air rising and cold air sinking

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.

A student has a glass of water as shown. She takes an ice cube from the freezer and puts the ice in the glass. Which explains the change that happens?

• The ice cube does not melt because cold flows into the ice cube from the water.

• The ice cube melts because cold flows out of the ice cube into the water.

• The ice cube does not melt because thermal energy transfers from the ice cube to the water.

• The ice cube melts because the thermal energy transfers to the ice cube from the water.

A metal spoon was left in a pot of boiling soup. The cook burned his finger by touching the spoon. Why did his finger get burned?

• The metal spoon chemically reacted with the cook's hand.

• The metal spoon insulated his hand.

• The metal spoon conducted thermal energy to the cook's hand.

• The metal spoon conducted electricity to the cook's hand.

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.
