Methan clathrate

WebMethane hydrate is a clathrate, a chemical substance made of one compound nested inside another. The word comes from the Latin clatratus, meaning "bars" or "lattice." One compound serves as a host, the other as a guest. In the case of methane hydrate, water is the host and methane is the guest.
