A river that weaves a snakelike path over the landscape?
What is a meandering river?
100
Define a floodplain.
An area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.

100
These are the two types of coast.
What are sandy and rocky?
200
Most Freshwater can be found here.
What are glaciers?
200
These are known as rivers or streams that flow into larger rivers.
What are tributaries?
200
A graph showing the rate of flow (discharge) versus time past a specific point in a river.
What is a hydrograph?
200
A part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes.
What is thermo-haline circulation.
200
What is the difference between a cutback and a pointbar?
Cutbacks are where the stream erodes away the river bank and the point bar is where sediment is deposited.

The lowest point to which a river can flow.
What is Base Level?
400
This is known as the volume of water flowing past any given point.
What is the discharge?
400
What is the difference between Eustatic and Local sea level change?
Eustatic is global whereas local is relative to certain areas.
400
If sediment credit exceed sediment debit, what will occur?
Deposition, increase of land area on or around beach.
