Greenhouse Gases changes in Atmospheric Chemistry

Which gas is most responsible for the greenhouse effect?

• Oxygen

• Nitrogen

• Carbon dioxide

• Argon

How does carbon dioxide contribute to the greenhouse effect?

• It absorbs and re-emits infrared radiation

• It blocks UV radiation

• It directly warms the Earth's core

• It reacts with methane to create heat

What human activity is the primary source of increased CO2 in the atmosphere?

• Volcanic eruptions

• Burning fossil fuels

• Deforestation

• Industrial waste

Which greenhouse gas has the highest heat-trapping potential per molecule?

• A. Carbon dioxide

• B. Methane

• C. Oxygen

What impact does deforestation have on atmospheric carbon dioxide levels?

• Decreases CO2 levels

• Has no impact

• Increases CO2 levels

• Converts CO2 into oxygen

Which of the following is NOT a greenhouse gas?

• Methane

• Carbon dioxide

• Water vapor

• Oxygen

What is the main source of methane emissions from human activities?

• Transportation

• Livestock and agriculture

• Ocean currents

• Wildfires

How does the greenhouse effect help maintain Earth's temperature?

• It reflects sunlight away from Earth

• It traps heat in the atmosphere

• It prevents the escape of oxygen

• It cools the planet

What effect does increased greenhouse gas concentration have on global temperatures?

• Decreases temperatures

• Increases temperatures

• No effect

• Stabilizes temperatures

What effect does an increase in atmospheric CO2 have on the climate?

• No effect

• Increases temperatures

• Causes an ice age
