Water Cycle Concepts and Processes

Taylor Sarsgard discusses the water cycle, a crucial topic for elementary students. The cycle involves three stages: evaporation, condensation, and precipitation, driven by the sun's heat. Evaporation turns water into vapor, condensation forms clouds, and precipitation returns water to Earth. This cycle is vital for recycling water, supporting life, and maintaining Earth's ecosystems.

Why did the speaker choose the water cycle as a research topic?

• Because it is not commonly known.

• Because it is related to climate change.

• Because it is a topic taught in early childhood education.

• Because it is a complex scientific concept.

What percentage of Earth's water is salt water?

• 100%

• 96%

• 75%

• 50%

Which stage of the water cycle involves water turning into vapor?

• Precipitation

• Transpiration

• Condensation

• Evaporation

What is the process called when water evaporates from plant leaves?

• Transpiration

• Sublimation

• Condensation

• Precipitation

How long can water vapor remain in the air before condensing?

• 10 days

• 1 day

• 5 days

• 20 days

What happens during the condensation stage of the water cycle?

• Water turns into vapor.

• Clouds form from water vapor.

• Water freezes into ice.

• Rain falls from the sky.

What is necessary for clouds to form in the atmosphere?

• Strong winds

• High temperatures

• High barometric pressure

• Low barometric pressure

In what forms can precipitation occur?

• Only as rain

• Only as hail

• As rain, snow, sleet, or hail

• Only as snow

What must water molecules do to form precipitation?

• Combine with dust or salt

• Evaporate into the air

• Melt into liquid

• Freeze into ice

What would happen if precipitation did not occur?

• Clouds would disappear.

• Water would vanish from bodies of water.

• The water cycle would speed up.

• Water bodies would overflow.
