why are gas hydrate deposits abundant in submarine continental margins?
gas hydrate forms in surface water offshore of continents where it sinks to the ocean bottom.
the ocean shields the gas hydrate from warming by the sun, which would cause it to dissolve.
continental margins tend to have high biological productivity, high pressures, and low temperatures.
there is plenty of water to form the ice - like compound.
the ocean contains abundant bacteria, which form the natural gas needed for gas hydrate.

Explanation:

Gas hydrates form under specific conditions of high pressure, low temperature, and the presence of gas sources. Continental margins have high biological productivity which can be a source of gas, and also offer the high - pressure and low - temperature environment required for gas hydrate stability.

Answer:

Continental margins tend to have high biological productivity, high pressures, and low temperatures.
