Waves

Height of a wave

• Wavelength

• Amplitude

• crest

wavelength

• Distance between two crests or two troughs

• height of the wave

• Frequency of the wave

The distance the wave travels before breaking on the shore

• Wavelenght

• Amplitude

• Fetch

Prevailing winds

• winds that blow from different directions

• winds that blow from a constant direction

• Winds that create distructive waves

Swash is when the waves break on the coast

• True

• False

Destructive waves

• strong swash, weak backwash

• weak swash, strong backwash

• swash and backwash are equal in strenght

Backwash

• waves move back into the sea at right angles to the coast

• waves move back into the sea at a perpendicular angle to the coast

• Waves move back into the sea parallel to the coast

If the fetch is long, the type of wave produced will be

• constructive

• destructive

• oscillation

Constructive waves

• strong swash, weak backwash

• weak swash, strong backwash

• swash and backwash are equal in strength

Destructive waves cause deposition to increase

• True

• False
