Coasts as natural systems：练习题

In the context of coastal systems, which of the following is accurately classified as a flow or transfer?

Within a coastal system, which process represents a flow or transfer of material?

Evaluate the relationship between landforms and landscapes within a coastal system. Which statement is most accurate?

Which process of marine erosion involves the sheer force of water crashing against a cliff, trapping and compressing air in cracks to cause rock fragments to break off?

In a coastal sediment cell, if the input of sediment exceeds the output of sediment, what is the likely outcome for the beach profile?

Explain how negative feedback helps maintain dynamic equilibrium within a coastal system.

Using a systems-based approach, evaluate the role of negative feedback and dynamic equilibrium in maintaining the stability of a coastal landscape. In your answer, you should:

a) Explain how a specific coastal process, such as beach profile adjustment, acts as a negative feedback loop when wave energy increases. (4 points)
b) Discuss why a state of dynamic equilibrium might be disturbed by human intervention through hard engineering strategies. (4 points)
