Wave Types and Coastal Processes Quiz

What determines the size and energy of a wave?

• The color of the water

• The fetch, strength of the wind, and duration of the wind

• The temperature of the sea

• The time of day

What is the swash?

• The distance between waves

• The movement of water down the beach

• The water flowing towards a beach when a wave breaks

• The height of the wave

Which type of wave is characterized by a strong backwash?

• Seismic wave

• Constructive wave

• They are steep and close together

• They have a strong backwash

What is the fetch?

• The speed of the wind

• The height of a wave

• The depth of the sea

• The distance a wave has traveled

What happens when there is energy loss in coastal processes?

• Waves become stronger

• Material is deposited

• Waves become taller

• Material is eroded

What is the backwash?

• The height of the wave

• The movement of water down the beach

• The distance between waves

• The water flowing towards a beach when a wave breaks

Which type of wave helps build up material on the beach?

• Seismic wave

• Tidal wave

• Constructive wave

• Destructive wave

What is a characteristic of destructive waves?

• They have a strong swash

• They build up the beach

• They are low and further apart

• They have a weak swash and strong backwash

What is sediment?

• Pieces of driftwood

• Small fragments of rock and soil

• Seaweed

• Large boulders
