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

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

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

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

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.

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

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

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

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

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
