TEST CH.2 Weather Patterns

1. What could have been different on Day 2 to cause rainfall?

• The air parcel was cooler than the surrounding air on Day 2, so it gained energy on Day 2 but not on Day 1.
• The air parcel was warmer than the surrounding air on Day 2, so it lost energy on Day 2 but not on Day 1.
• The air parcel was at the same low temperature as the surrounding air on Day 2, so it had low energy on Day 2 but not on Day 1.

P.39 the layer of the atmosphere closest to Earth, where weather happens

• cloud
• air parcel
• troposphere
• atmosphere

P.40 Which statement best describes how the sun heats the air?

• Energy from the sun is transferred to the air.
• Energy from the sun is transferred to Earth's surface, and some of this energy is then transferred to the air.

One of the claims that is used to explain the severe rainstorms in Galetown is this: Warmer weather caused Galetown to have more severe storms. Does the evidence below support or refute that claim?

• It supports the claim.
• It refutes the claim.
• It neither supports or refutes the claim.

Page 50 Why did the warm temperatures lead to more rainfall?

• Warmer air means more evaporation and more water vapor in a parcel. Warmer air parcels also rise higher in the troposphere and so they lose more energy and cool more.
• Warmer air means more evaporation and more water vapor in a parcel. Warmer air parcels also rise lower in the troposphere and so they gain more energy and heat more.

Page 50 When does the air parcel stop losing energy?

• When the air parcel reaches a higher temperature than the surrounding air.
• When the air parcel reaches the same temperature as the surrounding air.
• When the air parcel reaches a lower temperature than the surrounding air.

There are many factors that influence the amount of rain. What pattern do we see in the factors that cause more rain? (Check all that apply)

• more water vapor
• more surface water
• higher temperature
• less water vapor
• less surface water

In this activity we focused on the starting temperature of the air parcel. How does the starting temperature influence the amount of rain?

• When the air parcel is warmer, it rises higher and its temperature changes more as it loses energy. This would cause more condensation and rain.
• When the air parcel is colder, it rises lower and its temperature changes less as it gains energy. This would cause less condensation and rain.

page 52 What pattern is there in the relationship between parcel height, the size of the rain clouds and the rainfall level?

• The higher the air parcel travels will make the cloud get bigger and the more rain falls.
• The lower the air parcel travels will make the cloud get smaller and the more rain falls.
• The higher the air parcel travels will make the cloud get smaller and the more rain falls.
• The lower the air parcel travels will make the cloud get bigger and the more rain falls.

What did you notice about what happens to an air parcel after it heats up?

• It rises.
• It falles.
• It doesn't move.
