we will separate a mixture of sand pebbles and grassgrass - winnowingsand - winnowingpebbles - handpicking .
At this point they are none of the above. They are sediment. If lithified they will form sedimentary rock.
Conglomerates.
Boulders
As wind blows the smaller sand particles away the larger heavier cobbles/pebbles remain, over time there is less and less sand between cobbles creating a surface of pebbles rather than sand.
it's a mixture !
Yes there is sand in cold deserts. Sometimes, it is mixed with other soils and small pebbles but it is still sand for the most part.
The Sand Pebbles was created in 1962.
If you mix cement ,sand and water you get mortar If you mix cement and stone pebbles or chips you get concrete Concrete.Sometimes gravel is mixed with it, too.
Wash the pebbles and sand in a sieve. This will wash through the sand and keep the larger pebbles in the sieve.
Not just any sand. Mortar sand. Mortar sand is a larger grain sand that has been washed and screened to remove any rocks or pebbles.
Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.

Grains of sand will move faster compared to pebbles. Sand is lighter and will easily get carried by wind, unlike pebbles, which are heavier in comparison.

Pebbles, because it takes for energy for the pebble to sink and so the pebbles are hevier and sink faster then the sand grains
