1 The Work of Streams Erosion Destroys the land

2 The Work of Streams Erosion Destroys the land Deposition Makes new land

3 The Work of Streams Erosion Destroys the land Deposition Makes new land Sediment Transport To move the land

4 The Work of Streams Erosion Destroys the land Deposition Makes new land Sediment Transport To move the land

5 The Work of Streams Erosion Destroys the land Deposition Makes new land Sediment Transport To move the land Moves particles away by abrasion, grinding or dissolving Drops small particles sorted by size as the stream slows

6 The Work of Streams Erosion Destroys the land Deposition Makes new land Sediment Transport To move the land Moves particles away by abrasion, grinding or dissolving Drops small particles sorted by size as the stream slows Dissolved Load Suspended Load Bed Load

7 The Work of Streams Erosion Destroys the land Deposition Makes new land Sediment Transport To move the land Moves particles away by abrasion, grinding or dissolving Drops small particles sorted by size as the stream slows Dissolved Load Suspended Load Bed Load Dissolved rock that enters the stream Sand, silt and clay that is moved by the stream Large particles moved along the bottom

10 Erosion Stream Valleys

11 Erosion Stream Valleys Channels cut by water eroding the land away down to the base level

12 Erosion Stream Valleys Channels cut by water eroding the land away down to the base level Narrow ValleysWide Valleys

13 Erosion Stream Valleys Channels cut by water eroding the land away down to the base level Narrow ValleysWide Valleys V-shaped, Stream profile rapidly drops Less erosion, cuts side to side

14 Erosion Stream Valleys Channels cut by water eroding the land away down to the base level Narrow ValleysWide Valleys V-shaped, Stream profile rapidly drops Less erosion, cuts side to side Floodplain

15 Erosion Stream Valleys Channels cut by water eroding the land away down to the base level Narrow ValleysWide Valleys V-shaped, Stream profile rapidly drops Less erosion, cuts side to side Floodplain Area of the valley the River overflows to
