Weathering, Erosion, and Deposition

By: William Stephens

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

The End!
