Answer #1

1- The composition of water is hydrogen and oxygen. And we know that organic matter need an anoxic environment for the preservation. That's why marine condition is more preferable for preservation. As in the composition we have hydrogen and oxygen so we can get both during the decomposition.

2- In comparison to hydrogen content the oxygen content is very less. Because high oxic environment is bad for the preservation.

3- As we know the composition of natural gas is CH4 so we require both carbon and hydrogen not the oxygen.

4- The biggest obstacle is the high amount of oxygen content. As oxygen oxidise the organic matter so the organic matters cannot be preserved. Without preservance how can we get good amount of natural gas.
