Topic 2 Lesson 2 Test

What is respiration?

• The amount of water in the atmosphere.

• When animals release water vapor in the air by breathing

• When plants release water vapor in the air

• The amount of snow created in the clouds

What is a cycle?

• Any series of events that repeat in the same order

• Any series of events that does not repeat

• When a batter hits a single, double, triple and home run all in the same game

• One event that does not repeat

Condensation occurs when:

• The dew point reaches 32 degrees

• Relative humidity is achieved

• Liquid water changes to water vapor

• Water vapor changes into liquid water

What needs to be present in the atmosphere for condensation to occur?

• A low heat index

• Tiny particles

• Objectivity/Subjectivity

• Mist

Which type of air can hold more water vapor?

• Cold air

• Saturated air

• Hot air

• Cycled air

What is a dew point?

• The percent of water vapor in the air

• A measure of the amount of water in the air

• A subjective measurement of the current weather

• The temperature at which condensation begins

What happens if the dew point is above freezing?

• Water vapor forms droplets

• Water vapor forms snow

• Water vapor forms hail

• Water vapor forms sleet

What happens if the dew point is below freezing?

• Water vapor forms droplets

• Water vapor turns into frost

• Water vapor turns into heat

• Water vapor turns back into water

What happens when water vapor condenses near ground level?

• Clouds are created

• Sleet is created

• Rain is created

• Fog is created

Humidity is:

• A measure of the amount of water vapor in the air

• The same as heat index

• Always colder than the heat index

• The percent of water vapor in the air compared to the maximum amount it can hold
