A group of students are working on developing a model to show the different gases in

the troposphere, the layer of the atmosphere where weather takes place. They have

decided to use different colored building blocks to represent the different amounts of

each of the following gases: red for nitrogen, white for oxygen, blue for water vapor, and

green for carbon dioxide.

​In their model, the greatest number of building blocks will be ________ .

• Blue

• Green

• Red

• White

Which of the following best explains what is happening in the part of the water cycle model labeled with the letter R?

• Gravity causes large water droplets to fall from the clouds as precipitation.

• Heat energy from the Sun cause liquid water to evaporate into water vapor.

• Water from precipitation collects on the ground and moves downhill as runoff.

• Lowering temperatures cause water vapor to condense into water droplets to form

  clouds.

What is the ​best ​explanation for why people are warned to move inland and away from the beach during the approach of a hurricane?

• Heavy rains can cause streets to flood.

• Strong winds can cause trees to blow over.

• Large amounts of hail can break glass and damage roofs.

What precautions would be the ​best ​for​ ​someone to take in order to reduce the impact of a tornado?

• Stay inside. Get out of water. Do not stand under trees.

• Pack an evacuation kit with food, water, medicine, money, and important papers.

• Find a safe place away from windows. If you cannot find shelter, lie flat in a ditch.
