Categorize
They are formed by distant storms which can be 100s of km away
These waves surge up the beach with a stronger swash
The waves are well spaced apart and are less powerful when they reach the coast.
low energy
They rear up to form towering waves before crashing down onto the beach
They destroy the beach
High energy
There is little forward movement when this type of wave breaks but there is a powerful backwash
They carry large amounts of sediment and ‘construct’ the beach
waves are formed by local storms close to the coast
This wave drags material away from the beach, eroding it (wearing it away)
They have a weak swash as little material is left behind on the beach
They have a strong swash which pushed material up the beach.
Organise these options into the right categories
