Day 1 and Day 2 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 the air parcel to cause rainfall on Day 2?

• 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.

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

There were two rainstorms last month. Before Storm 1, Marion’s temperature at the surface was 26°C. Before Storm 2, the air temperature at the surface was 14°C. The temperature of areas surrounding Marion was the same before both storms.

Which storm is likely to have had more rainfall?

• Storm 1. The air parcel at the surface was warmer and had more energy, so when it moved higher, it lost more energy.

• Storm 1. The air parcel at the surface was warmer and had more energy, so when cooler air from above came down, it lost more energy.

• Storm 2. The air parcel at the surface was cooler and had less energy, so when it moved higher, it gained more energy.

• Storm 2. The air parcel at the surface was cooler and had less energy, so with low energy it remained near the surface.

We had two rainstorms in February. Storm 1 had more rainfall than Storm 2. The temperature of the surrounding areas was the same before both storms.

What conditions could have caused Storm 1 to have more rainfall than Storm 2? Before Storm 1, it could have been:

• warmer than before Storm 2 and windy. Wind pushed more water vapor out of the warmer air parcel.

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

• cooler than before Storm 2 and windy. Wind caused the cooler air from above the air parcel to move down, causing the cooler air parcel at the surface to lose more energy.

• cooler than before Storm 2 and windy. Wind pushed the cooler air parcel even higher and the air parcel gained more energy.

Air Parcel 1 is warmer than the surrounding air. Air Parcel 2 is at the same temperature as 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 will lose more energy to the surrounding air, which will cause more water vapor to fall as rain.

• Air Parcel 1 will gain energy from the surrounding air, which will cause more water vapor to fall as rain.

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