Understanding Climate Change Dynamics

What is the primary cause of the increase in greenhouse gas emissions?

• Deforestation

• Industrial activities

• Volcanic eruptions

• Solar flares

Which of the following gases is considered the most significant greenhouse gas contributing to global warming?

• Oxygen

• Nitrogen

• Carbon dioxide

• Argon

How do greenhouse gases affect Earth's energy balance?

• They increase the amount of solar energy reaching Earth.

• They trap heat in the atmosphere, preventing it from escaping into space.

• They reflect sunlight back into space, cooling the Earth.

• They absorb all forms of energy, including light and sound.

Which of the following is a natural process that removes carbon dioxide from the atmosphere?

• Photosynthesis

• Combustion

• Respiration

• Fossil fuel burning

What is the term used to describe the exchange of energy between Earth's surface and the atmosphere?

• Energy flux

• Energy balance

• Energy transfer

• Energy cycle

Which of the following is an example of a positive feedback loop in the context of climate change?

• Increased cloud cover reflecting sunlight and cooling the Earth

• Melting ice reducing the Earth's albedo and causing more warming

• Increased plant growth absorbing more carbon dioxide

• Volcanic eruptions releasing particles that block sunlight

What is the role of the ocean in regulating Earth's climate?

• It absorbs and stores large amounts of heat.

• It reflects sunlight back into space.

• It produces greenhouse gases.

• It blocks the escape of heat from the atmosphere.

Which of the following human activities is a major source of methane emissions?

• Transportation

• Agriculture

• Manufacturing

• Deforestation

What is the effect of increased atmospheric carbon dioxide on ocean chemistry?

• It makes the ocean more alkaline.

• It has no effect on ocean chemistry.

• It increases the ocean's salinity.

• It causes ocean acidification.

Which of the following is a potential consequence of global climate change?

• Decreased sea levels

• Increased frequency of extreme weather events

• Stabilisation of global temperatures

• Reduction in greenhouse gas concentrations
