When the water slows down, for example by reaching flatter land, it starts to drop the particles it is holding. It drops the largest particles first and the smaller ones as it slows down even further.<\/p>\n\n\n\n<p>Alluvial fans are a feature typically created when sediment carried by a mountain stream is deposited due to a rapid change in slope from a high to a low gradient. When the slope angle is high, the stream flows with a high velocity and is able to transport larger pieces of sediment such as pebbles and sand. When the slope angle is lower the stream loses the energy it needs to carry these larger pieces of sediment and they are deposited. The deposited materials eventually spread out, creating an alluvial fan.<\/p>\n\n\n\n<p>&nbsp;Water may also carry dissolved material \u2013 mostly ions that have minerals it has dissolved from solid rock. These ions may be deposited en route to the sea or may reach the ocean and contribute to its saltiness.<\/p>\n\n\n<figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2021\/06\/P514814.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;Alluvial fans around Loch an Duin, Scotland.

Material carried by the sea is washed up by the water and begins to build up along the coastline, creating beaches and other coastal features such as spits and shoals. Beaches change and move by the combined action of tides, waves and currents and can lose or gain sand from season to season.

As they move, they carve the landscape below them, picking up sediments and rocks of all sizes. In fact, glaciers can carry the largest of sediments \u2014 boulders, which can sometimes reach enormous sizes \u2014 for very long distances. When the glaciers melt and retreat, they leave them behind as what are known as \u2018glacial erratic boulders\u2019, made of rock that has no relation with the local geology where they have come to rest. <\/p>\n\n\n\n<p>The typical deposit of a glacier is known as &#8217;till&#8217;, which is an mixture of all the debris that the glacier was carrying at that moment, such as clay, sand, pebbles and boulders.
