Greenhouse gas released during earthquakes contributes to global warming

The video discusses the presence of methane hydrates on Earth's continental shelves and highlights methane's role as a potent greenhouse gas. It also covers the 1945 earthquake in the North Arabian Sea, which led to a significant release of methane into the sea and atmosphere.

What are methane hydrates?

• Methane mixed with other gases in the air

• Solid structures trapping methane on ocean floors

• Gaseous methane in the atmosphere

• Liquid methane in underground reservoirs

How does methane compare to carbon dioxide in terms of greenhouse effect?

• Methane is less potent than carbon dioxide

• Methane is equally potent as carbon dioxide

• Methane is 20 times more potent than carbon dioxide

• Methane is 50 times more potent than carbon dioxide

Which of the following statements about methane in the atmosphere is true?

• Methane is not present in the atmosphere

• Methane and carbon dioxide are equally abundant

• Methane is less abundant than carbon dioxide

• Methane is more abundant than carbon dioxide

What natural event in 1945 led to the release of methane?

• A hurricane

• An earthquake

• A tsunami

• A volcanic eruption

How much methane was released due to the 1945 earthquake?

• More than 1 million cubic meters

• More than 5 million cubic meters

• More than 7 million cubic meters
