Hydrological Cycle Evaporation ↓ Transpiration ↓ Condensation ↓ Precipitation ↓ Water runoff ↓ Groundwater Courses - River Channel Gradient Amount of Water Upper Narrow Steep Little Middle Wide more gentle More Lower Widest very gentle Most  Speed + Volume = Energy of river. Factors affecting speed of the river -Gradient of channel -Roughness/friction with obstacles -Welted perimeter (Size or shape of channel) Factors affecting volume of water in the river. -Size of drainage basin -Presence of vegetation -Permeability of rocks -Climate River processes --Transportation Traction > Roll or Slide Saltation> bounce Suspension> Float Solution > Disolve --Erosion Corrasion > Widen and deepens by grinding Attrition > Collides and break into smaller pieces Solution > Acid Rain Hydraulic Action > Loosen rocks and soil -Deposition |
