Beaches composed of pebbles and other larger materials are usually described as intermediate or reflective beaches. They usually have a steep offshore slope and are narrow and steep in relief. Waves are either 'collapsing' or 'surging' in character with a strong swash and weak backwash. Hence larger pebble material is driven onshore under a strong swash and then deposited as the backwash is too weak to remove it. Also, on pebble beaches quite a bit of energy in the backwash will be lost via percolation (usually 33-50%) which further weakens the backwash.

What is the diference between a pebble and a rock?
A pebble is a small, smooth stone typically under 2.5 inches in diameter, while a rock is a larger, naturally occurring mineral material. Pebbles are usually found on beaches or riverbeds, while rocks can vary greatly in size and are part of the Earth's crust.
Which rock was most likely formed from pebble-sized sediment deposited in shallow water at an ocean shoreline?
Conglomerate rock is most likely formed from pebble-sized sediment deposited in shallow water at an ocean shoreline. As the pebbles accumulate, they cement together to form the rock.
What is an antonym for boulder?
It's a PEBBLE.
What is likely to have formed farthest from the shoreline. pebble conglomerate or quartz sandstone or silty shale or shell limestone?
Because sandstone, silty shale, and shell limestone usually have origins of formation on or near shore, the pebble conglomerate is left. Pebble conglomerates are formed from deposition of water transported rocks of larger size than the smaller rock particles which compose sandstone and shale. The larger size indicates they were transported and deposited further from the shoreline.
Why are the rocks and stones found on pebble beaches usually rounded and smooth?
Because the tides act as a rock tumbler, it slowly smooths them out.More Information:Rocks found on beaches can be smooth for various reasons. The most common is that the washing motion of the waves erodes the sharp corners off over time by knocking little bits of sand and clay into them.Rocks along beaches can also be smooth if they happened to be deposited by glaciers. Rocks brought to a location because of the moving of glaciers long ago are rounded by tumbling around in front of the glaciers.
Are there any different types of beach?
It depends what you mean by that... Many beaches have black sand and many have white... Hope this helps. Sorry if it doesn't. Also, you can have sandy beaches and stone/pebble beaches. Nude beaches and non-nude beaches.
