| What is Erosion? | -This is the Act of the River Bed and Banks being Worn away.
-It also breaks up rocks that are Carried by the River |
| What is Hydraulic Action? | -This is the Power of the Water hitting the River Banks.
-Air can be Trapped in the Cracks of the Bed and Bank, and the Water forces the Air to Vibrate and Destroy the Rock |
| What is Abrasion? | -This is simply Pebbles Grinding along the River Bed and Bank
-Like Sandpaper |
| What is Attrition? | -This is the Rocks knocking each other
-They get Progressively smaller and more Rounded |
| What is Solution? | -When the Water can Dissolve the Rock
-Limestone is an Example |
| What is Transportation? | -The act of the River picking up Sediment and Carrying it downstream |
| What is Saltation? | -This is pebbles bouncing along the River Bed
-This is more Frequent near the Source of the River |
| What is Traction? | -Its Large and Heavy pebbles being Rolled along the River Bed
-This is more Frequent near the Source of the River, because the Load is bigger up there |
| What is Suspension? | -This is Lighter Sediment being Carried in the Water
-More Frequent near the Mouth of the River |
| What is Solution? | -This is transporting Chemicals that have been Dissolved.
-This can be varied along the River, because of the Presence of Soluble Rock |
| What is Deposition? | -This is the Act where the River drops of Material that its been carrying, due to Not enough Energy to keep it. |
| What are some of the Factors that can result into Deposition | -Shallow Water
-End of the River's Journey
-Volume of Water decreases |
| What is the Drainage Basin? | -This is the Area of the Land that the River drains the Water from. |
| What is a Watershed? | -This is area of High land, marking the Edge of the River Basin |
| What is the Source? | -This is the Start of the River |
| What is the Mouth? | -This is when the River meets the Sea |
| What is a Confluence? | -This is the Point when 2 Rivers meet |
| What is a Tributary? | -This is when a Small River, or Stream that has Joined on to a Larger River |
| What is a Channel? | -This is where the River flows |
| What is the River Long Profile? | -This is a Line from the Source to the Mouth
-This can show how the River changes overs its Course |
| What would the Typical Upper Course of a River be? | -Its Upland Area
-Load is Large, as the Erosion processes hasn't taken Place [Rocks haven't broken down yet]
-Its more Rough [Terms of Load]
-More Turbulence |
| What would the Typical Lower Course of a River be? | -Land is more Flatter
-Load is more Fine, as Erosion has happening here
-Most Discharge here [Most Units of Water per Second] |
| What is the Cross Section of a River? | -This shows the Cross-Section of the River's Channel [How wide and deep it is]
-Shows the Valley, which the River flows in |
| What would the Upper Course Cross Section be? | -Since the River flows Downhill here, cause the Mouth is at High Altitudes, Vertical Erosion takes place here. [V shaped Valley]
-The Channel is shallow and narrow, as there isn't a lot of Water Yet |
| What would the Middle Course Cross Section be? | -The river here still uses Vertical Erosion, but not as much as Lateral Erosion
-Increase in Lateral Erosion results in the River is more Deeper, whilst also being Deeper as well |
| What would the Lower Course Cross Section be? | -The River has a lot Less Erosion, barring some Lateral Erosion
-The River is at its most Deepest, and Widest |
