Weather Unit Test Review

What happens to molecules as the temperature increases?

• They move slower and spread out

• They move faster and spread out

• They move slower and get closer together

• They move faster and get closer together

What causes precipitation to fall?

• Precipitation become too heavy for updrafts to hold them up, so gravity pulls them down

• Precipitation becomes too heavy for gravity to hold them up, so updrafts pull them down

• Updrafts are too strong and move the precipitation to a new location where it can fall

• Gravity always pulls precipitation down

Which of these is not considered a weather condition?

• Precipitation

• Wind

• Temperature

• Color of the sky

How does the temperature of the atmosphere compare to the temperature of the ground?

• The ground is colder than the atmosphere

• The ground is warmer than the atmosphere

• The ground and the atmosphere have the same temperature

• The ground is more humid than the atmosphere

What happens to the temperature the closer you get to the ground?

• Temperature decreases as you get closer to the ground

• Temperature increases as you get closer to the ground

• Temperature does not change as you get closer to the ground

• Temperature goes up and down as you get closer to the ground

Why does the ground get warmer?

• It absorbs heat from the sun

• It is warmed by the people who walk on it

• It reflects heat from the sun

• Heat from the sun passes through the ground causing it to be temporarily warm

Which of these substances will be the hottest in the summer?

• Grass

• Sidewalk

• Blacktop

• Dirt

How do molecules transfer energy?

• Molecules reflect energy that other molecules can absorb

• Molecules release energy when they move around, and other molecules can pick up the loose energy

• Molecules transfer energy to each other by being close to each other

• Molecules transfer energy by colliding (bumping into)with each other

On which type of day would you expect air molecules to move the most?

• Sunny Day

• Rainy Day

• Cloudy Day

• Snowy Day

Which of these is not found in air?

• Oxygen

• Silicon
