7th Grade Science End of Year Review

Colin watched the weather report on television. He saw the forecast for the coming week. He knows that the water cycle follows certain steps in a repeating cycle. When the sun heats water molecules, they increase speed and collide. On Sunday, he noticed that a puddle on the sidewalk was getting smaller over time. Which step in the water cycle would Colin predict is occurring?

• Crystallization

• Condensation

• Evaporation

• Precipitation
