THE MOVMENT OF EROSION MATRAIL BY THE RIVER. |
|
Floatation |
MATERIAL MAY FLOAT IN A RIVER. |
|
SALTATION |
when material is bounced along the river bed. |
|
Dragged {TRACTION} |
MATERAIL MAY BE DRAGGED ACROSS THE RIVER BED. |
|
SUSPENSION |
WHEN MATERIAL IS HELD UP BY WATER. |
|
DEPOSITION |
WHEN THE RIVER DROPS MATERIAL IT HAS CARRIED |
|
DISSOLVED |
WHEN MATERIAL ARE NO LONGER VISABLE IN THE WATER |
|
EROSION |
IS A MATERIAL WEARING AWAY ROCKS |
|
River |
a natural stream of water of fairly large size flowing in a definitecourse or channel or series of diverging and converging channels. 2.a similar stream of something other than water: a river of lava; a river of ice. |

|
Resistant Rock |
A hard rock which resists being worn down and stands out as hills |
|
Non-Resistant Rock |
IS A HARD ROCK THAT HAS COME LOOSE |
|
Hydraulic Action |
Is erosion that occurs when the motion of water against a rock surface produces mechanical weathering. Most generally, it is the ability of moving water (flowing or waves) to dislodge and transport rock particles. |
|
Abrasion |
The process of scraping or wearing something away. |
|
Plunge Pool |
A deep basin excavated at the foot of a waterfall by the action of the falling water. |
|
Undercut |
1. To cut away the under part of (something) |

|
Ledge Waterfall |
Water descends vertically over a vertical cliff, maintaining partial contact with the bedrock. |
|
Block/Sheet |
Water descends from a relatively wide stream or river. |
|
Classical |
Ledge waterfalls where fall height is nearly equal to stream width, forming a vertical square shape. |
|
Curtain |
Ledge waterfalls which descend over a height larger than the width of falling water stream. |
|
Plunge |
Fast moving water descends vertically, losing complete contact with the bedrock surface. The contact is typically lost due to horizontal thrust of the water before it falls. It always starts from a narrow stream. |
|
Punchbowl |
Water descends in a constricted form and then spreads out in a wider pool |
