Greenhouse Gases and Global Warming

The video explains global warming, starting with the greenhouse effect, where gases like carbon dioxide, methane, and nitrous oxide trap heat from the sun, keeping Earth warm. While these gases are beneficial in moderation, human activities such as industrialization and deforestation have increased their levels, thickening the greenhouse layer and causing global warming. This warming makes Earth less habitable, highlighting the need for balance in greenhouse gas emissions.

What are the primary greenhouse gases mentioned in the video?

• Oxygen, Nitrogen, and Argon

• Carbon Dioxide, Methane, and Nitrous Oxide

• Helium, Neon, and Krypton

• Hydrogen, Helium, and Methane

How do greenhouse gases help maintain Earth's temperature?

• By reflecting sunlight away from Earth

• By absorbing all sunlight

• By trapping heat from the sun

• By cooling the Earth's surface

What would happen if the greenhouse gases did not trap heat?

• Earth would become much warmer

• Earth would become much cooler

• There would be no change in Earth's temperature

• Earth would become uninhabitable due to extreme heat

What human activities are increasing greenhouse gases?

• Industrial emissions and deforestation

• Recycling waste

• Using solar panels

• Planting more trees

How does deforestation affect the balance of greenhouse gases?

• It has no effect on greenhouse gases

• It decreases methane levels

• It reduces carbon dioxide absorption

• It increases the number of trees

What is the result of a thicker layer of greenhouse gases?

• More heat is trapped, leading to global warming

• Less sunlight reaches Earth

• Earth's temperature remains stable

• More heat escapes into space

What is the term used to describe the increase in Earth's temperature due to trapped heat?

• Thermal Equilibrium

• Global Warming

• Climate Neutrality

• Global Cooling

What is the main consequence of global warming?

• Increased global temperatures

• More frequent snowfalls

• Stabilized weather patterns

• Decreased sea levels

Who is responsible for global warming according to the video?

• Only developing countries

• All humans

• Only governments

• Only large corporations

What can be done to reduce the impact of global warming?

• Build more factories

• Reduce energy consumption and emissions

• Increase deforestation

• Ignore the problem
