Sediment is any piece of the Earth that has broken off and been transported elsewhere. The further sediment gets transported from its point of origin the smaller and rounder it gets. When enough accumulates in one spot the deeper sediment gets compressed into a sedimentary rock.

Geologists look at sedimentary rocks and pick out the size and shape of sediment in order to decipher environments from an ancient age.
