Global Warming and Climate Change

The video explains global warming as the increase in Earth's temperature due to the greenhouse effect, where gases like CO2 trap heat. Human activities, such as burning fossil fuels and deforestation, have increased these gases, leading to climate change. The video discusses ways to reduce emissions, like using renewable energy and reducing fossil fuel consumption.

What is the primary process that keeps Earth's climate as it is?

• The ozone layer

• The carbon cycle

• The water cycle

• The greenhouse effect

Which of the following is a major source of increased carbon dioxide in the atmosphere?

• Wind turbines

• Burning fossil fuels

• Solar panels

• Hydroelectric power

How does deforestation contribute to higher CO2 levels?

• By creating more space for solar panels

• By reducing the number of trees that absorb CO2

• By increasing oxygen production

• By enhancing the greenhouse effect

Which of the following is a method to reduce greenhouse gas emissions from transportation?

• Increasing air travel

• Building more highways

• Walking or biking instead of driving

• Using more gasoline

What is a benefit of using renewable energy sources like solar or wind power?

• They are non-renewable

• They require deforestation

• They increase fossil fuel consumption

• They can reduce or eliminate emissions
