- Geography
- Rivers water on the land
- The land forms produced by rivers are mainly the result of 3 processes
- Erosion
- the landscape is worn by 4 main types of erosion
- Abrasion (corrasion}
- Hydraulic Action
- Solution (corrosion}
- Attrition
- It can be vertical ( wearing away the bed pf the river } lateral (wearing away the banks } or headwards (eating back into the hillside at the source of the river }
- the landscape is worn by 4 main types of erosion
- Transport- Transportation
- Saltation
- Traction
- Solution
- Suspension
- There are two other processes
- weathering-The breaking up of rock by elements of the weather (sunshine , rain, frost} in situ
- mass movement - This is the downslope movement of loose material due to gravity e.g landslides ,slumping, soil creep
- Deposition
- A river will begin to drop its load when it runs out of energy needed to carry it. This loss of energy is usually caused by a decrease in volume or velocity as occurs when the gradient decreases or when a river enters the sea
- Erosion
- The landforms of a river and its valley
- Waterfalls and rapids
- Gorges
- Interlocking spurs
- Potholes
- Meanders
- Ox Bow Lakes
- Levees
