Understanding Global Warming

The video tutorial explains global warming as an imbalance in Earth's ecosystem due to rising temperatures in the atmosphere, oceans, and land. It highlights human activities like greenhouse gas emissions and deforestation as primary causes. The impacts include melting ice caps, rising sea levels, extreme weather, and threats to wildlife. To mitigate these effects, the video suggests recycling, conserving energy, and enhancing plant growth to absorb carbon dioxide.

What is global warming primarily described as?

• A decrease in atmospheric temperatures

• A natural cooling process

• A reduction in ocean levels

• An imbalance in the Earth's ecosystem

Which gas is known for trapping heat in the atmosphere?

• Greenhouse gas

• Oxygen

• Nitrogen

• Helium

What role do forests play in the context of global warming?

• They help balance oxygen and carbon dioxide levels

• They increase carbon dioxide levels

• They are the main source of greenhouse gases

• They contribute to soil erosion

What is one of the consequences of melting ice caps?

• Increased food supply for polar bears

• Rising sea levels

• Decreased global temperatures

• Expansion of polar habitats

How does global warming affect sea levels?

• It causes them to decrease

• It stabilizes them

• It has no effect on sea levels

• It causes them to rise

What is a potential impact of extreme weather conditions?

• Decreased rainfall

• Increased agricultural productivity

• More stable weather patterns

• Frequent natural disasters

How might global warming alter habitats?

• By reducing biodiversity

• By bringing significant changes to natural homes

• By causing no changes

• By making them more suitable for all species

What is one way to help mitigate global warming?

• Increase fossil fuel usage

• Reduce recycling efforts

• Conserve energy and use efficient appliances

• Cut down more trees

Why is recycling important in combating global warming?

• It reduces the need for new resources

• It increases greenhouse gas emissions

• It has no impact on the environment

• It increases waste production

What role do plants play in reducing greenhouse gases?

• They increase atmospheric temperatures

• They have no effect on greenhouse gases

• They absorb carbon dioxide for photosynthesis

• They release more carbon dioxide
