Understanding Global Warming Concepts

The video explains global warming as the increase in Earth's temperature due to human activities. It highlights the role of greenhouse gases from cars, factories, and other sources in thickening the atmospheric blanket, trapping heat. The greenhouse effect is likened to a glass house that retains warmth. NASA reports a significant temperature rise since the 19th century. The video concludes by questioning human responsibility and suggesting daily actions to reduce emissions.

What does global warming imply about the Earth's temperature?

• The Earth is getting warmer.

• The Earth's temperature is stable.

• The Earth is cooling down.

• The Earth's temperature fluctuates randomly.

Which of the following is NOT a human activity contributing to global warming?

• Operating factories

• Using air conditioners

• Driving cars

• Growing plants in a greenhouse

What is the primary function of a greenhouse?

• To trap heat and keep it warm

• To allow rain inside

• To block sunlight

• To cool down the environment

How does the greenhouse effect relate to Earth's atmosphere?

• It allows all heat to escape into space.

• It traps heat, similar to a greenhouse.

• It blocks all sunlight from reaching Earth.

• It cools down the Earth's surface.

What is the effect of a thicker atmospheric 'blanket' on Earth's temperature?

• It allows more heat to escape.

• It traps more heat, increasing temperature.

• It has no effect on temperature.

• It cools the Earth down.

What has NASA reported about the Earth's temperature change since the 19th century?

• The Earth is 2.5 degrees warmer.

• The Earth is 1.78 degrees warmer.

• The Earth is 1.78 degrees cooler.

• The Earth's temperature has not changed.

What can individuals do to help reduce greenhouse gas emissions?

• Use more plastic products

• Cut down more trees

• Use public transportation

• Increase the use of fossil fuels

Why is it important to address global warming?

• To increase Earth's temperature further

• To maintain Earth's current temperature

• To prevent further temperature rise

• To decrease Earth's temperature drastically
