Example water cycle quiz questions

What is the process where liquid water turns into water vapor?Evaporation. Heat from the sun turns liquid water into vapor, which rises from oceans, lakes and soil into the air.

True or false: transpiration is the release of water vapor from plant leaves.True. Plants release water vapor through tiny pores in their leaves called stomata, adding moisture to the air.

What do we call water that falls from clouds as rain, snow, sleet or hail?Precipitation. Water droplets or ice crystals in clouds grow heavy enough to fall back to Earth.

What process forms clouds when water vapor cools into tiny droplets?Condensation. Cooler air holds less vapor, so the vapor turns into liquid droplets or ice crystals that gather into clouds.

Which water store holds most of Earth's fresh water as ice?Glaciers and ice caps. Frozen water stays in these stores for long periods before melting back into the cycle.
