To do this you will would normally use a large wire filter where holes are set at about the size of sand. By vibrating this net area it sifts out the sand leaving rocks in the netting - It can be undertaken by multiple operations where holes in the netting become smaller so filtering page to small grains/rock.
A crude method is using a rake to drag away large rocks from sand
No, sandstone is not a pure substance. Sandstone is a mixture of eroded rock particles (grains of sand) that have been put under pressure over millions of years until they have formed a solid (sandstone) rock layer.Sandstone is a sedimentary rock, mainly of sand-sized mineral particles or rock fragments. Sandstone is mainly composed of quartz or feldspar.
they don't turn rocks into sand
I would say rocks.
Plants and animals are the biotic (living) factors and soil, sand, gravel, rocks and water are abiotic (nonliving) factors.
Yes. Many deserts have rocks in them (called hamada deserts). Large rocks in the deserts are in very unusual shapes due to the erosion of the sand and the wind. After years of sandstorms finally the rocks will crumple and turn into sand themselves.

A magnet can be used to quickly separate the iron paperclips from the mixture, as the paperclips are magnetic and will be attracted to the magnet. To separate the sand from the mixture, pouring the mixture through a sieve can help separate the larger sand particles from the smaller iron paperclips.
use a magnet
To separate this mixture, you could first use a magnet to separate the iron filings. Then, you could add water to dissolve the sugar, leaving the sand and sawdust behind. The sawdust can be separated from the sand by filtration.
we will separate a mixture of sand pebbles and grassgrass - winnowingsand - winnowingpebbles - handpicking .

Using a centrifuge to separate by density.
You could use a magnet to separate the iron fillings from the mixture, as iron is magnetic while the other substances are not. Next, you could use water to dissolve the salt, allowing you to separate it from the sand and gravel mixture. Finally, you could use a sieve to separate the remaining sand and gravel mixture based on particle size.
Dissolve the sugar in water and then evaporate the water
To separate sand and salt, you can use the process of filtration. First, add water to the mixture to dissolve the salt. Then, pour the mixture through a filter to separate the sand, which will be left behind, from the salt solution that passes through. Finally, evaporate the water from the salt solution to retrieve the salt.
to separate the mixture of sand and sugar:- first: you can mix water in it and after mixing you can separate the water and sand. and after that you boil the water until whole water is evaporated and you get sugar and sand separated. second: if difference b/w size of sugar and sand particle you can use met to separate them.
Let it sit. Sand is more dense than water, and will sink to the bottom of the solution.
