Class 4 EVS Worksheet: Water Cycle

EVS lesson 21: The water cycle · Set 150 · 40 questions
TalentJR

Remember (Up, cool, down): Evaporation: water → vapour (puddles dry, wet clothes dry). Condensation: vapour → drops (clouds, drops on a cold glass). Freezing: water → ice. Melting: ice → water. Precipitation: rain, hail and snow falling. Water boils at 100 °C at sea level and freezes at 0 °C.
