Greenhouse Effect

The video explains the greenhouse effect, where Earth's atmosphere traps heat from the sun, making the planet warm and habitable. It compares this process to a greenhouse, where gases like water vapor, carbon dioxide, methane, nitrous oxide, and ozone play a crucial role. Human activities, such as burning fossil fuels, increase these gases, leading to global warming. This warming affects global weather patterns and the habitats of plants and animals.

What role does the Earth's atmosphere play in the greenhouse effect?

• It traps heat from the sun, keeping the Earth warm.

• It allows all heat to escape into space.

• It absorbs all the heat from the sun.

• It reflects all sunlight back into space.

Which of the following is NOT a greenhouse gas?

• Methane

• Water vapor

• Carbon dioxide

• Oxygen

How do human activities contribute to the increase of greenhouse gases?

• By planting more trees

• By burning coal and oil

• By using solar panels

• By conserving water

What is the term used to describe the warming of the Earth due to increased greenhouse gases?

• Global warming

• Global cooling

• Climate change

• Ozone depletion

What impact does global warming have on the environment?

• It causes changes in weather and affects habitats.

• It stabilizes weather patterns.

• It increases the number of plant species.

• It reduces the Earth's temperature.
