level questions: River Processes [Done]

QuestionAnswer
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
