  1. Water as a FORCE Erosion & Weathering FLIPBOOKS!

  2. Flipbook setup YOUR NAME WATER as a FORCE Staples! Title Your name Section headings WATERSHEDS RIVERS CARVE GLACIERS CARVE WATER EXPANDS AS IT FREEZES FORCES THAT AFFECT WATERSHEDS

  3. Watersheds • What’s a watershed? • How are watersheds separated from other watersheds? • How are streams classified? On diagram, label: 1. Watershed: Land area from which all water drains into a common body of water 2. Divide: Border of all watersheds 3. Stream order: Classification of streams based on # of tributaries.

  12. Frost Wedging

  13. Water expands as it freezes. • Water expands as it freezes. It gets in a crack in a rock. Then it freezes. Then it expands. What happens to the crack? Make a 4-panel step-by-step drawing (with explanation) of the frost wedging process. WATER EXPANDS AS IT FREEZES

  14. What factors affect a watershed? Climate Hot Cold • Climate • Physical Features (topography) • Soils and geology • Vegetative cover Physical Features Mountain Flat Soils & Geology Plush soil Rocky Vegetative Cover Lots of plants Few plants FORCES THAT AFFECT WATERSHEDS
