	The water cycle is the circuit of water movement from the oceans to the atmosphere and to the Earth, returning to the atmosphere through various stages such as a solid, liquid and gas, via processes such as precipitation, interception, runoff, infiltration, percolation, storage, evaporation, and transportation. (from water dictionary of USGS)

	1. Is the water cycle really a cycle? 2. If we had a year with higher temperatures and less rainfall, what might happen to water quantity?

	Ohio Sea Grant does not have specific materials on this topic. We recommend Project WET's "Incredible Journey" activity.

	Other "Water Cycle" related Activities 1. 2nd graders' view of the water cycle 2. Earth's water: Rivers and the landscape 3. Water in the atmosphere 4. Observing Clouds 5.
