Beach Terraces
A berm refers to the way the sand on an ocean
beach is shaped under the surface of the water.
The shape is different in the summer and the
winter due to the intensity, and possibly other
seasonal attributes, of the waves.
winter bermshigh energy storm waves often cut
back a berm, washing away the finer sediment,
leaving a higher, coarser winter berm
