They're both silicon, so there shouldn't be any difference. Sand might stack up more tightly than gravel though.
No, sand's grains are finer (smaller) than gravel.
No. A grain of sand is a lot smaller than a piece of gravel.

A yard of dry gravel weighs more than a yard of dry sand. One yard of dry gravel is equal to 2970lbs/cu. yd while one yard of dry sand weighs 2619lbs/cu. yd
Sand is more fine than gravel
No. Sand and gravel are two different terms for describing sediment size. Gravel is a size up from sand.
Gravel has a significantly higher permeability than clay. Typically gravels have saturated hydraulic conductivity values (K) in the range of 1x10-2 to 1x10-3 m/s whereas clays will range from 1x10-8 for layered clays down to 1x10-14 m/s for non weathered clays.

sand is carried farther than gravel because it weighs less and doesn't get stuck together.
The more gravel you have, the more it weighs.

sand is a base and gravel is a acid
Sand and gravel are dug out of open quarries on the surface.
Sand and gravel can be separated by sifting them through a mesh, that will allow the sand to fall through, but will hold back the gravel.
Sand and gravel together
Gravel and sand are broken rocks.
