Understanding Methane: Dangers and Solutions

What is the main reason methane is considered dangerous?

• It is a potent greenhouse gas.

• It is difficult to detect.

• It is highly explosive.

• It is expensive to produce.

Why is methane used as a fuel despite its dangers?

• It is more abundant than other fuels.

• It is cheaper than other fuels.

• It is easier to transport.

• It emits less carbon dioxide than coal or oil.

What is the purpose of adding an odorant to natural gas?

• To make it more flammable.

• To help detect leaks by smell.

• To increase its energy content.

• To reduce its greenhouse effect.

What makes methane a more potent greenhouse gas than CO2?

• It is heavier than CO2.

• It has more vibrational modes that trap heat.

• It reacts faster with other gases.

• It is more abundant in the atmosphere.

How do methane detectors identify the presence of methane?

• By capturing methane in a container.

• By using lasers to detect methane's vibrational modes.

• By detecting the smell of methane.

• By measuring the temperature of the air.

What is a common method to deal with concentrated methane leaks?

• Freezing the methane.

• Storing it underground.

• Burning it to convert into CO2.

• Diluting it with water.

What is a potential solution for capturing low concentrations of methane?

• Freezing it into a solid form.

• Burning it immediately.

• Employing chemical catalysts that mimic microbial processes.

• Using high-pressure containers.

What is a 'super emitter' in the context of methane leaks?

• A type of methane detector.

• A large source of methane emissions.

• A device that captures methane.

• A natural source of methane.

Why is it important to address methane emissions now?

• Methane is running out.

• Methane does most of its damage in the near term.

• Methane is becoming more expensive.

• Methane is no longer used as a fuel.

What role do microorganisms play in methane management?

• They produce methane.

• They consume methane at low concentrations.

• They convert methane into water.

• They store methane for later use.
