Answer:
The answer is pressure from overlying rock transforms organic matter into liquid form.
Step-by-step explanation:
When gas molecules are surrounded in a lattice of water molecules at temperatures above 0°C and pressures above one atmosphere, they can form a steady solid. These solids are known as gas hydrates. Most gas hydrates are molded from methane (CH4) . These hydrate beds leak gases into the water, forming cold leaks on the ocean flooring.
