  • Sedimentary rocks topex.ucsd.edu

    Sediment becomes a sedimentary rock through a process known as lithification. Lithification begins when rocks are buried and become compacted. The pores of the rock then become filled with cement, and certain minerals begin to recrystallize. Sediment is loose material and sedimentary rock holds together when you pick it up.
