Global Warming/Greenhouse Gases

Front

What is global warming?

Back

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space and thus warming the planet.

Front

What is the primary source of carbon dioxide emissions?

Back

The primary source of carbon dioxide emissions is the burning of fossil fuels such as coal, oil, and natural gas.

Front

What is the atmosphere?

Back

The atmosphere is the mixture of gases that surrounds the Earth, composed mainly of nitrogen (78%) and oxygen (21%).

Front

Which layer of the atmosphere do we live in?

Back

We live in the troposphere, the lowest layer of the atmosphere where weather occurs.

Front

How does deforestation contribute to global warming?

Back

Deforestation contributes to global warming by reducing the number of trees that can absorb CO2, leading to higher concentrations of greenhouse gases in the atmosphere.

Front

What are some actions individuals can take to reduce global warming?

Back

Individuals can reduce global warming by conserving energy, using public transportation, recycling, and reducing meat consumption.

Front

What is the relationship between CO2 levels and global temperatures?

Back

As carbon dioxide concentrations increase, global temperatures tend to increase, indicating a direct relationship.

Front

What role do oceans play in climate regulation?

Back

Oceans absorb a significant amount of CO2 and heat, helping to regulate the Earth's climate and mitigate the effects of global warming.
