With reference to the Gas Hydrates, which of the following statements...
Option c is correct.
- Relevance: Gas Hydrates can be a potential source of energy for India.
- Statement 1 is correct: Gas hydrates are ice-like crystalline minerals that form when low molecular weight gas (such as methane, ethane, or carbon dioxide) combines with water and freezes into a solid under low temperature and moderate pressure conditions. They are crystalline solids formed of water and gas.
- Statement 2 is correct: In terrestrial conditions, gas hydrates are formed naturally under the sea bed and glaciers under high pressure, low temperature conditions. Knowledge Base: Most gas hydrates are formed from methane (CH4), which has led to the terms “gas hydrate” and “methane hydrate” often being used interchangeably. Methane hydrate is a potential source of natural gas.
For us, hydrate deposits are important for a variety of reasons:
1) Gas hydrate deposits may contain roughly twice the carbon contained in all reserves of coal, oil, and conventional natural gas combined, making them a potentially valuable energy resource.
2) Their decomposition can release large amounts of methane, which is a greenhouse gas that could impact Earth’s climate.
3) Sudden release of pressurized methane gas may cause submarine landslides, which in turn can trigger tsunamis.
4) Gas hydrates in the ocean can be associated with unusual and possibly unique biological communities that use hydrocarbons or hydrogen sulfide for carbon and energy, via a process known as chemosynthesis.

With reference to the Gas Hydrates, which of the following statements...
Gas Hydrates:
- Gas hydrates are crystalline solids formed of water and gas molecules. They are a unique form of ice that consists of a lattice-like structure of water molecules with trapped gas molecules occupying the spaces within the lattice.
- Gas hydrates can form under specific conditions of high pressure and low temperature. In terrestrial conditions, they are naturally formed under the seabed, particularly in continental margins, where the pressure is high and the temperature is low enough to stabilize the hydrate structure.
- The gas molecules trapped within the hydrate lattice can include methane, ethane, propane, and other hydrocarbons, as well as carbon dioxide and nitrogen. Methane hydrate, in particular, is the most common and well-studied form of gas hydrate.
- Gas hydrates are found in abundance in the permafrost regions of the Arctic and in deep ocean sediments. They are estimated to contain a significant amount of natural gas worldwide, making them a potential future energy resource.
- The formation of gas hydrates occurs when gas molecules come into contact with water molecules under the right pressure and temperature conditions. The water molecules arrange themselves in a cage-like structure to form a hydrate, trapping the gas molecules within the lattice.
- Gas hydrates are stable under high-pressure conditions, but they can dissociate and release the trapped gas molecules when the pressure is reduced or the temperature is increased. This dissociation process can be triggered by various factors, such as changes in the surrounding environment or human activities like drilling.
- Gas hydrates have attracted significant scientific and industrial interest due to their potential as a future energy resource and their impact on climate change. The release of methane from dissociating hydrates has the potential to contribute to greenhouse gas emissions and influence global climate.
- Research and exploration efforts are ongoing to better understand gas hydrates, their formation, stability, and potential applications. This includes studying their distribution, properties, and potential extraction techniques while also considering their environmental implications.
