6.3 Weather Lessons 1-6

Front

What is density?

Back

Density is a measurement that describes how closely packed the air particles are.

Front

What is conduction?

Back

Conduction is the direct transfer of heat from one substance to another substance that it is touching.

Front

What happens to air particles that lose thermal energy?

Back

Air particles that lose thermal energy will slow down and come closer together, becoming more dense and sinking.

Front

What is condensation?

Back

Condensation is the process where water vapor molecules lose energy, stick together, and form a liquid.

Front

Why does warm air rise?

Back

Warm air rises because it gains energy and becomes less dense.

Front

What is the relationship between temperature and density?

Back

As temperature increases, density typically decreases because particles move faster and spread apart.

Front

What is evaporation?

Back

Evaporation is the process where liquid water gains energy and turns into water vapor.

Front

What is relative humidity?

Back

Relative humidity is the amount of water vapor present in the air compared to the maximum amount the air can hold at that temperature.

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, including processes like evaporation, condensation, and precipitation.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.
