Why do pebbles go smaller the closer you are to the sea?
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.

Why are some beaches made of sand and some are made of pebbles?
Some beaches are made of sand because bigger particles are eroded by waves. Some beaches are made of pebbles because smaller particles are eroded by waves. I'm not sure about the sand one but the pebbles one I pretty sure I'm right. Hoped this helped! +++ I can amplify that a little. The beach material depends on its primary source, but is always from rocks that have been eroded from the land. ' So if the rocks are principally sandstone they break back down to sand. If they are harder rocks, the beach will be boulders or shingle; if the source rocks is clay and shale the beach will be of clayey mud. Estuary beaches tend to be covered with richly-organic silt brought down by the river. ' If the coastal land is principally Chalk rich in flints (as in my own part of the world) the chalk dissolves away leaving the flints, and these become eroded down to rounded pebbles, as on Chesil Beach, on the Southern English coast.

Why do different beaches have different types if sand?
Wave action is the culprit If a headland is being eroded, it will create a rocky beach Also more powerful waves will deposit larger sediment, so some otherwise beaches will have rocks on the beach, and those rocks will be closest to the water, because heavier sediments will be deposited first, because the wave will lose energy as they slow down beaches with just sand will have less powerful waves, so the the largest sediment that will be deposited will be grains of sand Tidal flats have even less powerful waves, in fact there will be next to no waves there and the the largest sediment will be silt and mud Of course, some beaches are artificial and all the sand is brought to them from elsewhere, or are naturally occurring beaches that are eroding too fast and much of that sand is also brought in from somewhere else and these beaches are often in overdeveloped areas.
