Glacial & Stream Erosion
• Glaciers erode a mountain side and create a “U” shaped valley
• Streams the flow down a steep gradiant or slope create a “V” shaped valley
![Page 23: Glaciers & Streams Part 2 Mr. King. How Glaciers Move Mountain Side](https://reader036.vdocuments.site/reader036/viewer/2022070403/56649f2f5503460f94c49aa8/html5/thumbnails/23.jpg)
Stream Erosion- Young
• Rapids • Waterfalls • No Flood Plain • Tributaries or small
streams connect main river
• Valley Being Deepened
![Page 24: Glaciers & Streams Part 2 Mr. King. How Glaciers Move Mountain Side](https://reader036.vdocuments.site/reader036/viewer/2022070403/56649f2f5503460f94c49aa8/html5/thumbnails/24.jpg)
Stream Erosion - Youth/Mature
• V-Shaped Valley
• Beginnings of Flood Plain
• Sand and Gravel Bars
• Sharp Divides
• Relief Reaches Maximum • Valleys stop deepening
![Page 25: Glaciers & Streams Part 2 Mr. King. How Glaciers Move Mountain Side](https://reader036.vdocuments.site/reader036/viewer/2022070403/56649f2f5503460f94c49aa8/html5/thumbnails/25.jpg)
Stream Erosion - Mature/Old age• Valley has flat bottom • Narrow Flood Plain • Divides begin to round off • Relief diminishes • Sediment builds up, flood
plain widens • River begins to meander • Lots of Disagreement from
here on; some geologists believe slopes stay steep but simply retreat.
![Page 26: Glaciers & Streams Part 2 Mr. King. How Glaciers Move Mountain Side](https://reader036.vdocuments.site/reader036/viewer/2022070403/56649f2f5503460f94c49aa8/html5/thumbnails/26.jpg)
Stream Erosion - Old Age
• Very Wide Flood Plain • Land worn down to flat
surface (Peneplain) • Resistant rocks form
residual hills (Monadnocks)
• Pronounced River Meanders
• Cut-off Meanders (Ox-bow lakes)
![Page 27: Glaciers & Streams Part 2 Mr. King. How Glaciers Move Mountain Side](https://reader036.vdocuments.site/reader036/viewer/2022070403/56649f2f5503460f94c49aa8/html5/thumbnails/27.jpg)
More Stream Erosion
• Rivers meander because the landscape is flat.
• Some Landscapes are flat because they are extremely ancient.
• Other Landscapes are flat for other reasons, like recent sediment deposition.

Rejuvenation of a stream
• Uplift of Land (Lowering of Sea Level, sometimes greater stream flow) causes stream to speed up and cut deeper.
• Stream valley takes on youthful characteristics but retains features of older stages as well.
• Can happen at any point in the cycle.
