what are the beach features of destructive waves?

A

steep becoming more gentle

28
Q

what are the beach features of constructive waves?

A

gentle becoming steeper

A

destructive waves

30
Q

at steep beaches what is the backwash like?

A

strong

31
Q

at steep beaches what is the swash like and why?

A

it’s weak as it slows it down more quickly

constructive

33
Q

at gentle beaches what is the backwash like?

A

weak

34
Q

at gentle beaches what is the swash like and why?
