Most gas hydrates form when what occurs? pressure from overlying rock transforms organic matter into liquid form. minerals crystallize from ocean water. bacteria break down organic matter trapped in ocean-floor sediments.

The answer is pressure from overlying rock transforms organic matter into liquid form.

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.
