Characteristics and Properties. Conglomerate is a sedimentary rock that looks like concrete. It consists of large, rounded pebbles (clasts) cemented by a matrix made of calcite, iron oxide, or silica. Conglomerate rock occurs where gravel can become rounded by traveling distances or being subjected to tumbling.

What is sand? Composition & Types of Sand

Composition & Types of Sand. Sand is a mixture of small grains of rock and granular materials which is mainly defined by size, being finer than gravel and coarser than silt. And ranging in size from 0.06 mm to 2 mm. Particles which are larger than 0.0078125 mm but smaller than 0.0625 mm are termed silt. Sand is made by erosion or broken pebbles ...
