The video explains the greenhouse effect, a natural process that maintains Earth's temperature. It details the composition of the atmosphere, highlighting gases like nitrogen, oxygen, and argon, and their roles. The video discusses the impact of increased greenhouse gases, such as global warming and climate change, and identifies human activities like burning fossil fuels and deforestation as causes. Finally, it suggests solutions to reduce emissions and combat climate change.

What is the primary role of the greenhouse effect on Earth?

• To eliminate all harmful gases from the atmosphere

• To cool down the Earth's surface

• To maintain the necessary conditions for life by trapping heat

• To increase the Earth's temperature to 30 degrees Celsius

Which gases make up the majority of Earth's atmosphere?

• Carbon dioxide, methane, and ozone

• Nitrogen, oxygen, and argon

• Water vapor, nitrous oxide, and ozone

• Chlorofluorocarbons and methane

Which gases have a greater impact on the greenhouse effect despite being less abundant?

• Hydrogen, helium, and neon

• Nitrogen, oxygen, and argon

• Water vapor, carbon dioxide, and methane

• Helium, neon, and krypton

What are chlorofluorocarbons and their role in the atmosphere?

• Natural gases that reduce global warming

• Artificial gases that contribute to the greenhouse effect

• Natural gases that cool the Earth

• Gases that have no impact on the environment

What happens when the concentration of greenhouse gases increases?

• The Earth's temperature decreases

• The atmosphere retains more heat, causing global warming

• The Earth's temperature remains constant

• The atmosphere releases more heat into space

Which of the following is a major cause of increased greenhouse gases?

• Burning of fossil fuels

• Increased use of renewable energy

• Planting more trees

• Reducing industrial activities

How does deforestation contribute to the increase in greenhouse gases?

• By decreasing methane emissions

• By increasing water vapor in the atmosphere

• By reducing carbon dioxide absorption

• By increasing oxygen levels

What is one way to combat climate change according to the video?

• Increase industrial production

• Increase the use of fossil fuels

• Reduce the emission of greenhouse gases

• Cut down more forests
