Burning Fossil Fuels and Climate Change

The video explains how human activities, particularly the burning of fossil fuels, have increased carbon dioxide levels in the atmosphere, leading to climate change and global warming. It discusses the natural greenhouse effect, the role of other greenhouse gases like methane and nitrous oxide, and the consequences of these changes, such as extreme weather and rising temperatures. The video emphasizes the difference between natural and enhanced greenhouse effects and the importance of understanding the carbon cycle.

What is the primary component of fossil fuels that contributes to increased carbon dioxide levels when burned?

• Carbon

• Nitrogen

• Oxygen

• Hydrogen

How does the additional carbon dioxide in the atmosphere affect the Earth's temperature?

• It cools the Earth's surface.

• It allows more heat to escape into space.

• It acts like a sweater, trapping more heat.

• It reduces the amount of sunlight reaching Earth.

Which of the following is NOT a source of methane, a greenhouse gas?

• Burning wood

• Car exhausts

• Cows

• Paddy fields

What is one of the consequences of increased energy trapped in the Earth's atmosphere?

• Melting glaciers and ice caps

• More stable weather patterns

• Decreased global temperatures

• Reduced sea levels

What is the role of the natural greenhouse effect?

• To keep the Earth warm enough for life

• To cool the Earth

• To reduce carbon dioxide levels

• To increase oxygen levels
