- Beaches are sloping bands of sand, shingle or pebbles along the edge of a sea or lake.
- Some beaches are made entirely of broken coral or shells.
- On a steep beach, the backwash after each wave is strong. It washes material down the beach and so makes the beach gentler sloping.
- On a gently sloping beach, each wave runs in powerfully and falls back gently. Material gets washed up the beach, making it steeper.
- The world’s largest pleasure beach is Virginia Beach, Virginia, USA, over 45 km long.
- Waves crashing against the shore can weaken cliffs and cause some to fall into the sea.
- The little bays in this beach have been scooped out as waves strike the beach at an angle.
- The slope of a beach matches the waves, so the slope is often gentler in winter when the waves are stronger.
- A storm beach is a ridge of gravel and pebbles flung high above the normal high-tide mark during a storm.
- At the top of each beach a ridge, or berm, is often left at the high-tide mark.
- Beach cusps are tiny bays in the sand that are scooped out along the beach when waves strike it at an angle.
