Evaporation occurs when the sun heats water molecules. Plants undergo transpiration when they transport water from their roots to the stem and leaves. Humans and animals breathe in oxygen that the plants create, and exhale carbon dioxide in the process of respiration.

What three words name the processes by which water vapor enters the atmosphere?

• Condensation, evaporation, and precipitation

• Evaporation, precipitation, and respiration

• Evaporation, transpiration, and respiration

• Condensation, transpiration, and evaporation

• The amount of rainfall.

• Temperatures falling below freezing.

• Snow

• Ice

Explain ALL stages of the water cycle and how the cycle affects weather (i.e. rain, snow, hail)?

Answer explanation

Evaporation occurs by the sun heating water on the ground and in bodies of water until water molecules speed up, which causes them to rise. This water vapor in the air causes humidity.

Precipitation falls from clouds when condensation becomes too heavy and gravity pulls the water down.

Clouds form when water vapor in the air rises, attaches to another water molecule, and cools, causing condensation and making the sky cloudy.

Precipitation will either fall as rain at warmer temperatures, or it will freeze when temperatures drop below freezing (32 degrees F).

Which description below BEST matches how a cold front forms and affects the weather?

• A cold front forms when a warm air mass pushes into a colder air mass.

  Cold fronts can produce small changes in the weather.

• A cold front forms when a warm air mass pushes into a cooler air mass.

  Cold fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.

• A cold front forms when a cool air mass pushes into another cool air mass.

  Cold fronts often bring fair weather as the cool air mass at the surface rises above the warm air.

• A cold front forms when a cold air mass pushes into a warmer air mass.

  Cold fronts can produce severe changes in the weather.
