Unit 4 — The Water Cycle

Science · Vocabulary Review

Evaporation.: The sun heats water in oceans, lakes and rivers, turning it into water vapor that rises into the air.
Condensation.: Water vapor cools as it rises and turns back into tiny liquid droplets, forming clouds.
Precipitation.: Droplets in a cloud combine until they are heavy enough to fall as rain, snow, sleet or hail.
Collection.: Fallen water gathers in oceans, lakes, rivers and underground, where the cycle begins again.
Transpiration.: Plants release water vapor into the air through tiny openings in their leaves.
Runoff.: Water that flows over the ground surface into streams and rivers instead of soaking in.
