海岸作用與海岸地貌：練習題

Which process of coastal erosion involves pebbles and rocks being thrown against the base of a cliff by the force of the waves?

Which of the following is an example of a soft engineering strategy used for coastal management?

Why are mangrove ecosystems particularly effective as a form of soft engineering for coastal defense against storm surges?

In which of the following climatic zones are coral reef ecosystems primarily found?

Which abiotic characteristic is a fundamental requirement for the growth and survival of mangrove ecosystems?

What are revetments and how do they reduce coastal erosion?

Explain the role of longshore drift in the development of a coastal spit.

Explain how the construction of groynes can increase erosion rates in coastal areas further down the coast.

Coastal landforms are created through a sequence of physical processes.
(a) Name two types of marine erosion that affect a headland.
(b) Explain the sequence of landform development from a cave to a stack.
(c) State how a stack eventually becomes a stump.

The development of coastal landforms is heavily influenced by the relationship between geology and marine processes.
(a) Explain how the interaction of discordant geology and wave refraction leads to the formation of headlands and bays.
(b) Evaluate the social and economic impacts of using hard engineering strategies (such as sea walls) versus soft engineering (such as beach replenishment) for the sustainable management of a coastal community.
