The pebbles are flint deposited in the chalk cliffs adjacent to Brighton. Through natural erosion the flints are released from the cliffs and slowly make their way through natural process to Brighton where the groynes are in place to "capture" the pebbles. You can see this in action as you can see a higher level of pebbles to the west of a groyne than on the easterly side.

Seashells wash up on shore through a combination of water currents, waves, and tides. These natural forces carry the shells from the ocean floor and deposit them onto the beach as the water recedes. Seashells are also left behind when marine animals die and their shells become detached from their bodies.
There are many types of beaches. A pink sand beach is made of crushed bit of seashells.
