River deposition — process?
Dropping of materials when flow slows.
Deposition conditions — example?
Entering lakes or seas, floodplain flooding.
Waterfalls — formation?
Erosion of soft rock beneath hard rock.
Hard vs soft rock — erosion?
Hard resists, soft erodes quickly.
Waterfall formation — key step?
Undercutting soft rock, overhang collapse.
Meanders — cause?
Lateral erosion creating winding bends.
Deposition occurs when?
Flow energy decreases, velocity drops.
Waterfalls — main agent?
Hydraulic action and abrasion.
Soft rock — erosion?
Erodes faster, forms waterfalls.
Hard rock — resistance?
Resists erosion, remains stable.
Meanders — inside bend?
Deposition, slip-off slopes form.
Waterfalls — retreat?
Upstream due to undercutting and collapse.
