This is to do with tide patterns and percolation. A wave's swash (wave going up the beach) is very powerful and has enough power to carry large pebbles up the beach. However on a pebble beach, a lot of the waves energy is lost filling the gaps in the pebbles. All those small spaces mean the wave loses power and its backwash (wave going back down the beach) is much weaker than its swash. Only the smaller pebbles can be pulled back down the beach. This leaves the larger pebbles further up the beach.

After the enzyme amylase breaks down a starch molecule, it breaks it into smaller sugar molecules called maltose.
Minerals are the component of soil that are formed by the weathering of rocks. Weathering breaks down rocks into smaller particles, which eventually contribute to the mineral content of soil.

It breaks into smaller fragments.
