Damaging Waters: Floods
Usually the result of excessive rainfall or from rough waves along coastal lowlands.

Dangerous Water: Avalanches
Avalanches: http://www.youtube.com/watch?v=ktuOCZrN2OU
An avalanche is a landslide of snow.
Snow on mountains may be undercut by wind, or repeated freezing and thawing could cause weak areas in the snow.

Erosion
The wearing away of rocks and earth (involes the moving away of partiles).
Run off from riverbanks carries sediment, (gravel, sand, silt and mud) into the river.
Heavy sediment in a river or stream can change the habitat of the plants and animals living there.

Weathering and Deposition
Deposition: The process where sediment settles on the bottom of a river. Can cause the filling in of rivers and lakes.
Weathering: The break up of rock due to exposure to the atmosphere.
Two types of Weathering: Mechanical and Chemical

Key Point!!
If a particle is loosened by weathering by stays put, it is weathering.
If the particle starts to move it is erosion!

Question 1: Weathering, Erosion or Deposition?
A waterfall fed by glacial runoff tumbles over sheer cliffs and into the turquoise water of Admiralty Inlet on Baffin Island, Nunavut, Canada.

Question 2: Weathering, Erosion, Deposition?
Sandbars swirl beneath Oregon Inlet in Cape Hatteras National Seashore on North Carolina's Outer Banks. Waves driven by ocean winds can cause the sandbars here to shift and change literally by the hour, making conditions hazardous for boats.

Question 3: Weathering, Erosion, or Deposition?
White lichens cover a blue granite gravestone like snow near Lake Champlain, New York.
