The Impact of Greenhouse Gases on Climate Change
What are greenhouse gases and how do they contribute to climate change?
a. Greenhouse gases are gases that trap heat in the Earth's atmosphere and contribute to climate change.
b. Greenhouse gases are gases that help cool the Earth's atmosphere and prevent climate change.
c. Greenhouse gases are gases that have no impact on the Earth's atmosphere or climate.
d. Greenhouse gases are gases that deplete the ozone layer and increase UV radiation levels.
Answer:
Greenhouse gases are gases that trap heat in the Earth's atmosphere and contribute to climate change.
Explanation:
Greenhouse gases, such as carbon dioxide, methane, and water vapor, act like a blanket around the Earth, trapping heat and preventing it from escaping into space. This natural process, known as the greenhouse effect, helps regulate the Earth's temperature and keep it within a habitable range.
However, human activities, such as burning fossil fuels, deforestation, and industrial processes, have dramatically increased the concentration of greenhouse gases in the atmosphere. This excessive buildup of greenhouse gases intensifies the natural greenhouse effect, leading to global warming and climate change.
Climate change caused by greenhouse gases has far-reaching consequences, including rising sea levels, more frequent and severe extreme weather events, and disruptions to ecosystems and food supplies. Addressing the issue of greenhouse gas emissions is crucial to mitigating the impact of climate change and preserving the planet for future generations.
