Gas hydrates are essentially crystalline solid cage like structures in which small molecules are trapped in a network of frozen water molecules. The trapped gas molecules are usually methane which is a natural gas.
These methane hydrates are formed when methane and water combine under high pressure conditions usually prevalent in the ocean floors. Gas hydrates are also regarded as a powerful candidates for the production of cleaner energy.
Gas hydrates are made up of Solid-Ice water and a natural gas like Methane gas trapped in the lattice of ice water. Gas hydrates are mainly found deep down in the sea where the atmospheric pressure is greater than 1 atm.
Generally Gas hydrates have two main applications.
a) It stabilizes the sea floor other wise its melting will cause land sliding in sea floor.
b) Secondly, it traps a green house gases like Methane, if released these gases could produce Climate changes.
Biosphere is just a planet. Solar system contains planets and star. Galaxy holds multiple solar systems only. Universe hold everything, biospheres, solar systems, and galaxies. I hope this helps :D
