Fresh Water

Streams & Rivers Runoff from precipitation forms streams, which flow together to form rivers. Rivers wear away landforms through erosion and build new ones through deposition. http://www.the7sisters.co.uk/free/pages/resource/modelling/rivers/rparts.htm

Stream or River?

Ponds and Lakes Ponds and lakes are bodies of standing water that form when fresh water collects in depressions in the land. Lake turnover is a seasonal mixing that refreshes the nutrient supply in the lake.

Pond or Lake?

Wetland Environments Wetlands provide nesting and feeding areas for birds and other wildlife. Wetlands also filter water and help control floods. http://www.dnr.state.wi.us/org/caer/ce/eek/nature/habitat/wetland1.htm

What Type of Wetland?

Glaciers and Icebergs Glaciers form when layers of snow pile up. Icebergs form when the edges of glaciers reach the ocean and break off.
