Weather and Heat Transfer

Which best explains why it is important for people to be able to identify cumulonimbus clouds?

• Cumulonimbus clouds can cause mild showers.

• Cumulonimbus clouds form near Earth’s surface, causing fog.

• Cumulonimbus clouds can cause severe thunderstorms.

• Cumulonimbus clouds form when the temperature is below

  freezing.

Why is it important to know the different types of clouds?

• Clouds can indicate the time of day that it is.

• Clouds can indicate the

  temperature of different layers of the atmosphere.

• Clouds can indicate the type of weather that will occur.

Which type of weather is usually associated with a cumulus cloud?

• fair

• humid

• foggy

• stormy

A scientist is collecting data over time using a barometer. What trends could best be revealed from the data?

• changes in cloud cover

• changes in temperature

• changes in air pressure levels

• changes in precipitation levels

Michael observes the air pressure daily. Over the last couple of days the air pressure has been dropping. What weather will Michael most likely observe as a result?

• increasingly clear skies and more wind

• increasingly cloudy skies and possible storms

• increasingly clear skies and dry weather

Which statement best explains how wind is formed?

• Air is warmed by radiation and air flow increases as a result of the warming.

• Unequal heating of the land causes air to flow from areas of higher pressure to areas of lower pressure.

• Pressure decreases as a result of frictional contact with earth causing air to flow more freely.

The weather forecast in today’s newspaper predicts rain throughout the entire day. Which describes how the sky will most likely look?

• sunny and clear of clouds

• mostly sunny with a few wispy clouds

• partly sunny with many puffy clouds

• mostly covered in low, heavy clouds

Which best describes a storm that forms over warm sections of the ocean?

• blizzard

• hurricane

• hail storm

What type of cloud is usually associated with thunderstorms?

• cirrus

• stratus

• cumulus

• cumulonimbus

Which type of weather is most often produced by a low air pressure system?

• cold

• hot

• rainy

• sunny
