    Sand is ground up rocks, not so fine that they float away as dust. Sand does not contain very fine ground rocks which would stick together as clay.  And it does not contain organic matter.  That's what sand is.

    Normal dirt contains sand, clay, dust, and decomposed plant materials.  The plant materials give crucial nutrients to plants that grow in the dirt.

    Sand is mostly made of the element silicon. Silicon is one of the most abundant elements on earth and is naturally found in rocks. When rock is eroded, it turns into sand.  There are not enough camels to produce sand.

    Sand is mineral, rock or soil particles that range in diameter from 0.02 to 2 mm.

    Sand is mostly SiO2.  Other common constituents are Al2O3 and CaCO3.  Source of sand is rock and shell fragments.  

    "Dirt" is usually a mixture of sand, silt, and clay, possibly with plant materials mixed in.  Silt contains many of the same elements as sand, but in much finer particle sizes, often the result of deposit by floods.  Clay particles are more sheet-like, which accounts for the sticky or slippery texture of clay.

    Depends on the sand. Some sand, especially beach sand, is comprised of tiny rocks and shells. A small patch of beach sand under a microscope is a microcosm of varipus sea life. Desert sand tends to be the result of wind erosion of rocks, whilst dirt is a mix of stuff including decomposing plant and animal material
