Unit Review Weather, Climate, and Water Cycling OpenSciEd

Front

What is the relationship between air temperature and its ability to hold water vapor?

Back

Colder air can hold less water vapor than warmer air.

Front

What conditions are necessary for cloud droplets to form?

Back

The air must reach 100% humidity, be cooled, and have cloud condensation nuclei (CCN) for the vapor to stick to.

Front

How do air masses influence storm formation?

Back

Many storms are influenced by the path an air mass follows as it moves.

Front

What are hailstones made of and how are they formed?

Back

Hailstones are made of ice and are often formed in layers.

Front

How does ocean temperature vary with latitude?

Back

The ocean is warmer near the equator and cooler near the poles.

Front

What is humidity?

Back

Humidity is the amount of water vapor present in the air.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

What is condensation?

Back

Condensation is the process by which water vapor turns into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface.

Front

What are cloud condensation nuclei (CCN)?

Back

CCN are small particles in the atmosphere that water vapor can condense onto, helping to form clouds.
