Global Warming and the Greenhouse Effect

Front

What is Global Warming?

Back

Global Warming refers to the gradual increase in the Earth's average temperature due to the accumulation of greenhouse gases in the atmosphere.

Front

What are Greenhouse Gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide, methane, and water vapor.

Front

What is the Greenhouse Effect?

Back

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

Front

Name three major greenhouse gases.

Back

Carbon Dioxide (CO2), Methane (CH4), and Water Vapor (H2O) are three major greenhouse gases.

Front

How does deforestation contribute to global warming?

Back

Deforestation reduces the number of trees that can absorb CO2, leading to higher concentrations of greenhouse gases in the atmosphere.

Front

What is the relationship between global warming and extreme weather events?

Back

Global warming can lead to more frequent and severe extreme weather events, such as hurricanes, droughts, and heatwaves.

Front

True or False: Global warming can affect sea levels.

Back

True. Global warming causes polar ice to melt and seawater to expand, leading to rising sea levels.

Front

What human activities contribute to global warming?

Back

Burning fossil fuels, deforestation, and industrial processes are human activities that contribute to global warming.

Front

What is the role of carbon dioxide in the greenhouse effect?

Back

Carbon dioxide absorbs infrared radiation emitted by the Earth, trapping heat in the atmosphere and contributing to the greenhouse effect.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, often linked to global warming.
