18 Questions
What is a common landform found in low energy coasts?
Beaches
Which of the following is a result of strong waves causing greater erosion than deposition in high energy coasts?
Cliffs
Where does sediment in coastal systems come from?
Streams/Rivers
How are sediment cells defined in coastal areas?
Distinct coastal areas separated by boundaries where sediment is either deposited or eroded
What happens if removal exceeds addition in a coastal sediment budget?
The coast recedes
How do sediment cells act in terms of sediment transport?
Closed systems where larger sediments stay within the cell
What type of landforms are commonly found in low energy coasts?
Beaches and spits
What is a typical result of strong waves causing greater erosion than deposition in high energy coasts?
Creation of cliffs
Which of the following is NOT a source of sediment in coastal systems?
Offshore sand banks
How do sediment cells function in terms of sediment transport?
Larger sediments are transported out, while smaller particles stay within the cell
In a coastal sediment budget, what happens if addition exceeds removal?
The coast advances
What characterizes sediment cells in coastal areas based on their boundaries?
Boundaries separate areas where sediment is either deposited or eroded
What is the primary difference between low energy coasts and high energy coasts?
Low energy coasts experience greater erosion than deposition, while high energy coasts experience greater deposition than erosion.
What major feature is often associated with sediment cells in coastal areas?
Boundaries where sediment is either deposited or eroded
How do sediment cells differ from coastal sediment budgets?
Sediment cells measure sediment addition and removal, while coastal sediment budgets measure the balance between the two.
Which of the following is a common source of sediment in coastal systems?
Cliff erosion
What happens to the coast when removal exceeds addition in a coastal sediment budget?
The coast recedes
Why do beaches and spits commonly form on low energy coasts?
As a result of greater deposition than erosion
