  1. Weathering, Erosion, and Deposition By: William Stephens

  2. Natural Erosion Example 1 • WHAT: A fallen tree in the water • WHERE: In the Chattahoochee River • HOW: Moving water eroded the ground around the tree

  3. Natural Erosion Example 2 • WHAT: Collapsed area on the river bank • WHERE: On the Chattahoochee River • HOW: Falling rain eroded the edge of the bank until the edge collapsed

  4. Erosion Caused by Man Example 1 • WHAT: A pipe near a lake • WHERE: My neighborhood • HOW: The pipe dumps water and erodes the land around it

  5. Erosion Caused by Man Example 2 • WHAT: A low muddy area • WHERE: My backyard • HOW: When the house was built, the backyard was sloped in a way that causes water to flow there and deposit mud

  6. Deposition of Sediments Example 1 • WHAT: Deposition in my creek. • WHERE: In my backyard. • HOW: The flow of the creek makes sediment come with it, then the sediment gets jammed in cracks.

  7. Deposition of Sediments Example 2 • WHAT: Sediment in a lake • WHERE: In my neighborhood • HOW: Rain washes dirt into the lake

  8. Weathering of Rock Example 1 • WHAT: cracked sidewalk • WHERE: in my neighborhood • HOW: when it’s cold, rain freezes, expands, and breaks the rock apart

  9. Weathering of Rock Example 2 • WHAT: cracked rock • WHERE: in my backyard • HOW: plant roots broke the rock apart

  10. Erosion Slowed by Man Example 1 • WHAT: Railroad ties (pieces of wood) • WHERE: In my yard • HOW: The wood prevents the soil and mulch up top from eroding down the hill

  11. Erosion Slowed by Man Example 2 • WHAT: A drain • WHERE: In the very back of my backyard • HOW: Rain goes in here instead of going through my yard and eroding it
