Which statement(s) about the foreshore are true?

• It is a very dynamic environment

• It is often made of sand

• Berms are formed here

• It is the zone between normal low tide level and the low tide level of the spring tides

What is a berm?

• A nearly horizontal shore parallel ridge formed on the beach due to the landward transport of the coarsest fraction of the beach material by the swash.

• Micro beach ridges parallel to the shoreline, created by wave action on low gradient beaches.

• Semi-circular depressions cut into the lower edge of the storm beach

• Ridges which are formed perpendicular to the shoreline formed due to the deposition of coarse mateiral
