Natural gas seeps are natural openings in the Earth's surface where natural gas escapes from underground reservoirs. This gas is primarily composed of methane, a potent greenhouse gas. These seeps can occur in various environments, including coastal areas, wetlands, and even on land, often resulting in visible bubbles in water or gas emissions in the air. These seeps can provide valuable information about the geological processes beneath the surface and the presence of fossil fuels. They also play a role in the natural carbon cycle, as the released methane can contribute to atmospheric greenhouse gas levels, impacting climate change.
