Lesson 2 - Water in the Atmosphere

Which of the following processes make up the water cycle?

• Evaporation, Condensation, Precipitation, Collection

• Photosynthesis, Respiration, Transpiration, Decomposition

• Erosion, Weathering, Sedimentation, Fossilization

• Combustion, Oxidation, Reduction, Fermentation

How does energy drive the processes of the water cycle?

• By providing heat for evaporation

• By cooling the atmosphere

• By increasing water density

• By reducing water flow

How does the water cycle affect the weather?

• By changing the temperature

• By influencing precipitation patterns

• By altering wind directions

• By affecting the Earth's rotation

What is the water cycle?

• A process involving the continuous movement of water on, above, and below the surface of the Earth.

• A method of water purification.

• A type of water sport.

• A seasonal change in water levels.

Evaporation is the process of:

• Condensation of water vapor into liquid

• Conversion of liquid into vapor

• Freezing of water into ice

• Sublimation of ice into vapor

Condensation is the process of:

• Turning a gas into a liquid

• Turning a liquid into a gas

• Turning a solid into a liquid

• Turning a liquid into a solid

What is the dew point?

• The temperature at which air becomes saturated with moisture and dew forms

• The temperature at which water boils

• The temperature at which ice melts

• The temperature at which air pressure is highest

Humidity is defined as the amount of what in the air?

• Oxygen

• Carbon Dioxide

• Water Vapor

• Nitrogen

Relative humidity is:

• The amount of water vapor in the air compared to the maximum it can hold at that temperature.

• The temperature at which air becomes saturated with moisture.

• The total amount of water vapor present in the air.

• The pressure exerted by water vapor in the atmosphere.

Precipitation is:

• The process of water vapor turning into liquid water

• The falling of water from the atmosphere to the ground

• The evaporation of water from surfaces

• The movement of water through the ground
