What is a beach?
Be READY TO LEARN
Think like a Geographer
Beaches are found on coasts between high and low tide
level. Beaches are deposits of sand that lies between the
high and low tide levels. Most beaches are formed of sand
and shingle (pebbles) as well as mud and silt. They are mainly
found in bays because the waves that enter the bay are
constructive waves that have a strong swash and build up the
beach.

What characterises a beach?
Pebble beaches are generally steep whilst
sandy beaches are generally shallow and
almost flat. The distance the beaches
stretch inland is not very far when the beach
is made up of pebbles however when the
beach is made up of sand, they do stretch a
long way inland.
Constructive waves are dominant at sandy
beaches whilst destructive waves are
dominant at pebble beaches. Towards the
back of a sandy beach, there may be sand
dunes whereas pebble beaches will have
larger pebbles at the back.

Beach Profiles
A beach profile shows the
gradient from the back of the
beach to the sea and the
characteristics in between. A
sandy beach generally has a
gentle, fairly flat profile,
whereas a pebble beach has a
steep, stepped profile.
A berm is a terrace on a beach that has formed in the backshore, above the water level
at high tide. On broad beaches there may be three or more berms formed under
different wave conditions. Berms are formed in calm weather when constructive waves
transport material onto the beach, whilst existing berms are moved up the beach by
storms and then new berms are formed changing the beach profile.

Beaches are formed when constructive waves deposits its load (1) as it
looses energy (1).
