They are composed of many different things. Structurally, they are each made up of two chromatids connected by a centromere. It is also made up of DNA(deoxyribonucleic acid), which is our genetic material.
They reduce the amount of leakage through small seep holes that sometimes form in the geomembrane part of the liner, this helps prevent plants & animals being harmed by the waste created by contaminated water.
