Whilst water is responsible for the deposition of the sediment, the concentration of larger pebbles results from deflation, a process associated with wind. Deflation occurs when winds blow across a bare desert surface selectively picking up fine sand and silt particles, leaving behind larger sediments to form a pebble-strewn desert pavement, or reg.

Sand particles are the biggest and weigh more than silt - so the bottom layer will be the sand part of the soil. Any pebbles will also be at the bottom. Next up is the silt layer. Silt particles are smaller than sand and weigh less so they appear over the sand. If you were able to separate out any clay particles they are the smallest and will be on

Examples include: Shale, sandstone, and conglomerate Clastic Sedimentary Rock Fragments can be as large as pebbles or as fine as silt. The fragments are carried by wind, waves, or glaciers and then deposited as kinetic energy is lost. Finer particles can be carried further before being deposited. Clastic Sedimentary Rock Water-deposited sediment: Natural cements (silica, …

Figure 4. The riverbeds (a & b) seen above are lined with boulders, cobbles, and pebbles. The streams in these locations are moving very fast (high-energy) and therefore all of the smaller sediment, like sand, silt, and clay, are carried down stream, leaving behind the larger sediment. The beach in the picture above (c) is in an area where the

Today we conducted our first experiment in the Pebbles, Sand, and Silt Science kit. Our investigation involved sifting and sorting a river rock mixture using three different size screens. Students were asked to sift as many different sizes of pebbles, gravel, and sand as they could and to separate them into cups.

2. Water– as rocks and pebbles roll along the bottom of flowing water, they bump and scrape against each other, causing these rocks to become rounded and smooth. 3. Wind– wind blows sand and silt against exposed rock eventually wearing away the rock's surface. 4.

 · The sand and silt have been there for at least tens of thousands of years, ever since the glaciers covering Maine, ground rocks into pebbles and pebbles into sand as they receded during the last

 · Pebbles that bounce along the sea/river bed. How are sand dunes formed? Beaches with a large tidal range means that there is exposed dry sand at low tide. This is blown to the back of the beach. When a river floods, fine silt/alluvium is deposited on the valley floor.

The riverbeds (a & b) seen above are lined with boulders, cobbles, and pebbles. The streams in these locations are moving very fast (high-energy) and therefore all of the smaller sediment, like sand, silt, and clay, are carried down stream, leaving behind the larger sediment.

Pebbles that bounce along the sea/river bed. When the sea or river loses energy, it drops the sand, rock particles and pebbles it has been carrying. This is called deposition. Heaviest material is deposited first. Bay. When a river floods, fine silt/alluvium is deposited on the valley floor.
