Clathrates

Definition

Clathrates are compounds where gas molecules, like methane, are trapped within a lattice of water ice. They are found in ocean sediments and permafrost and can impact global climate by releasing greenhouse gases.

5 Must Know Facts For Your Next Test

1. Clathrates primarily store methane, a potent greenhouse gas.
2. They are stable under high pressure and low temperature conditions found in deep ocean floors and permafrost regions.
3. Melting clathrates due to rising temperatures can release large amounts of methane into the atmosphere.
4. This release of methane from clathrates can exacerbate global warming.
5. Clathrate deposits are considered both a potential energy resource and a significant risk for climate change.
