Which process changes water from a gas to a liquid? A. B. C. D. Evaporation Condensation Precipitation Runoff

B. Condensation

Which statement best describes runoff? A. B. C. D. Water vapor cools off and changes into water droplets. Water in the form of rain, snow, sleet, or hail falls from the clouds. Precipitation that falls to Earth ultimately flows over land into lakes, streams and rivers. Water from the oceans and the surface of the earth changes in to water vapor.

C. Precipitation that falls to Earth ultimately flows over land into lakes, streams and rivers.

Which best describes the correct order of the water cycle? A. B. C. D. Precipitation, runoff, condensation, evaporation, precipitation Precipitation, runoff, evaporation, condensation, precipitation Precipitation, evaporation, condensation, runoff, precipitation Precipitation, evaporation, runoff, condensation, precipitation

B. Precipitation, runoff, evaporation, condensation, precipitation

During evaporation, what change best describes what happens to water? A. B. C. D. A gas changes into a liquid. A gas changes into a solid. A liquid changes into a gas. A liquid changes to a solid.

C. A liquid changes into a gas.

A student picks up a glass of water and gets her hand wet. What most likely caused her hand to get wet? A. B. C. D. The table was wet. The water in the glass evaporated. Some of the ice in the water melted. Condensation formed on the outside of the glass.

D. Condensation formed on the outside of the glass.
