Day 1 and Day 2 in Pine Brook started with the same amount of water vapor in the air parcels in the area.

It rained at the end of Day 2 but it did not rain at the end of Day 1.

What could have happened with the air parcel on Day 2 to cause rainfall?

• The air parcel was warmer than the surrounding air, so it gained energy.

• The air parcel was warmer than the surrounding air, so it lost energy

• The air parcel was cooler than the surrounding air, so it gained energy.

Florida had two rainstorms in July. Storm 2 had more rainfall than Storm 1. The temperature of the surrounding areas was the same before both storms. What could have caused Storm 2 to have more rainfall than Storm 1? Before Storm 2, Florida could have been:

• warmer than before Storm 1 and windy. Wind pushed more water vapor out of the warmer air parcel.

• cooler than before Storm 1 and windy. Wind pushed the cooler air parcel even higher and the air parcel gained more energy.

• cooler than before Storm 1 and windy. Wind pushed more water vapor out of the warmer air parcel.

• warmer than before Storm 1 and windy. Wind pushed the warmer air parcel even higher and the air parcel lost more energy.

There were two rainstorms in Greenville last fall. Before Storm 1, Greenville's temperature was 9°C. Before Storm 2, the temperature was 26°C. Before both storms, the temperature of the surrounding areas was the same and wind was blowing toward Greenville. There was the same amount of water vapor before Storm 1 and Storm 2. Which storm likely had more rainfall?

• Storm 2. Wind pushed more water vapor out of the warmer air parcel.

• Storm 1. The cooler air parcel had less energy at the surface, so when wind pushed it higher, it gained more energy.

• Storm 2. Wind pushed the warmer air parcel even higher and the air parcel lost more energy.

• Storm 1. Wind caused cooler air from above the air parcel to move down, causing the air parcel at the surface to lose more energy.

Day 1 and Day 2 in Greenville started with the same amount of water vapor in the air parcels there. It rained at the end of Day 2 but it did not rain at the end of Day 1. What could have happened to cause the rain?

• The air parcel was warmer than the surrounding air, so it lost energy.

• The air parcel was warmer than the surrounding air, so it gained energy.

• The air parcel was at the same low temperature as the surrounding air, so it had low energy.

Air Parcel 1 is the same temperature as the surrounding air. Air parcel 2 is warmer than the surrounding air. Air Parcel 1 and Air Parcel 2 started with the same amount of water vapor in them. Which air parcel will have more rainfall and why?

• Both air parcels will have the same amount of rain. They have the same surrounding air temperature, so the same amount of water vapor will fall as rain.

• Air Parcel 1 is colder than Air Parcel 2, so more water vapor will fall as rain.

• Air Parcel 2 will gain energy from the surrounding air, which will cause more water vapor to fall as rain.

• Air Parcel 2 will lose energy to the surrounding air, which will cause more water vapor to fall as rain.

There were two rainstorms in Sinan last month. Before Storm 1, Sinan’s temperature was 30°C. Before Storm 2, the temperature was 15°C. Before both storms, the temperature of the surrounding areas was the same and wind was blowing toward Sinan. There was the same amount of water vapor before Storm 1 and Storm 2.

• Storm 1 because it has a warmer air parcel which will rise higher in the troposphere losing more energy and condensing more water vapor into rain.

• Storm 2 because cooler air parcels rise higher in the troposphere causing more energy loss, condensation and rain.

As an air parcel rises energy transfers

• out into the surrounding air

• in from the surrounding air

• both directions and the energy of each stays the same
