The formation of salt-tolerant plants on tidal mudflats.
The collapse of bubbles in waves causing pressure waves that break up rock.
The cyclical rise and fall of sea levels due to gravitational forces.
The process of sediment being transported along the coast.
Answer explanation
Cavitation refers to the collapse of bubbles formed in waves, which generates pressure waves that can break up rock. This process is significant in coastal erosion and shaping of shorelines.

Which type of wave is associated with the build-up of beach material?
Destructive wave
Constructive wave
High energy wave
Low energy wave
Answer explanation
Constructive waves are characterized by their ability to deposit sand and build up beach material, making them essential for beach formation. In contrast, destructive waves erode beaches.

What characterises a Dalmatian coast?
A series of ridges and valleys running parallel to the coast.
A coastline with high energy waves.
A ridge of sediment parallel to the coast.
An ecosystem formed on tidal mudflats.
Answer explanation
The Dalmatian coast is characterized by a series of ridges and valleys that run parallel to the coastline, resulting from geological processes. This unique topography distinguishes it from other coastal formations.

What is the main characteristic of a destructive wave?
Long wavelength and low frequency.
Short wavelength and high frequency.
High energy and low erosion.
Low energy and high deposition.
Answer explanation
Destructive waves are characterized by short wavelengths and high frequencies, leading to greater energy and erosion. This contrasts with the other options, which describe different wave types.

What is littoral drift also known as?
Wave quarrying
Longshore drift
Sediment budget
Weathering
Answer explanation
Littoral drift, the movement of sediment along the coast due to wave action, is commonly referred to as longshore drift. This process is crucial in shaping coastal landscapes.
