Weather Unit 1 QUIZ

What is it called when plants give off water vapor as a product of photosynthesis?

• condensation
• evaporation
• precipitation

• transpiration

You walk outside on a cool summer morning and notice the grass is wet despite that it did not rain. Which statement best explains what happened?

• Water can only appear on grass when it rains, so it had to have rained that night.

• Warm, moist air was cooled down to the dew point temperature during the night, which caused water vapor to condense into liquid on the cool grass.

• Water was taken up by the grass from the soil and then "sweated" out by the grass.

• There is no explanation for the water on the grass. It must have just appeared.

On which kind of day would you expect the most evaporation from the surface of a pond?

• cold, rainy
• cold, sunny
• warm, rainy
• warm, sunny

What is precipitation?

• Liquid water gaining energy and turning into water vapor which rises higher in the atmosphere.

• Water vapor being given off by plants as a byproduct of photosynthesis.

• Water vapor losing energy and turning into liquid water droplets forming clouds.

• Any form of water that falls from the sky.

On Earth, what process generates MOST of the water vapor?

• Condensation

• Evaporation

• Precipitation

• Transpiration

The image shows various stages in the water cycle. Which number is showing transpiration?

• 1

• 2

• 3

• 4

What are clouds made of?

• dry air

• only liquid water droplets

• water vapor (gas)

• liquid water droplets, ice crystals, and particles of dust/dirt

Which statement describes the movement of air particles based on heat in the atmosphere?

• Cool air is heated by the Earth's surface which rises higher in the atmosphere, cools off, and sinks back down to Earth to be reheated.

• Warm air is cooled by the Earth's surface which rises higher in the atmosphere, warms up, and sinks back down to Earth to be cooled again.

• Warm air is heated by the Sun which sinks lower in the atmosphere, cools down, and rises back up to be reheated.

• Cool air is heated by the Sun which rises higher in the atmosphere and stays there.

A student draws a model to represent the processes involved in the water cycle, as shown. To which process is the formation of clouds related?

• Condensation

• Evaporation

• Precipitation

• Transpiration

In which environment would the potential for evaporation be the highest?

• Over a cool ocean

• A forest in the middle of a continent

• A hot rainforest

• A desert
