• As water vapor expands, it forms tiny droplets of water or ice crystals.

• Cold air holds less water than warm air.

• If the dew point is above freezing, ice crystals will form.

• As air cools, the amount of moisture it can hold decreases.

• Cold air holds more water than warm air.

• If the dew point is above freezing, water droplets will form.

• As water vapor condenses, it forms tiny droplets of water or ice crystals.

• As air cools, the amount of moisture it can hold increases.

• The temperature at which condensation begins is called the DEW POINT.

• The temperature at which condensation begins is called RELATIVE HUMIDITY.

At night, after a long humid day, the ground cools. The cold Earth also cools the air just above the ground. The next morning, the sun causes the water droplets that are close to the ground to condensate.

What does this create?

• Fog

• Rain

• Specific Humidity

• A front

Match the following situations to how the relative humidity will be affected.

• Relative Humidity May Stay Same

• Air temperature grows warmer, and moisture is taken from the air.

• Relative Humidity Will Drop

• Air temperature grows colder, and no new moisture is added to the air.

• Relative Humidity Will Rise

• Air temperature grows warmer, and new moisture is added to the air.

How does energy from the sun cause evaporation?

• It causes animals to have transpiration

• It attracts water molecules

• It breaks the bond between the water molecules

• It breaks the bond between the water and the ground
