Snowmelt Runoff and the Water Cycle

Perhaps you've never seen snow. Or, perhaps you built a snowman this very afternoon and perhaps you saw your snowman begin to melt. Regardless of your experience with snow and associated snowmelt, runoff from snowmelt is a major component of the global movement of water, possibly even if you live where it never snows.  Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.
