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

12. The End! 
