Environmental Science - Climate Change

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes.

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat in the atmosphere, keeping the Earth warm enough to support life.

Front

What is ocean acidification?

Back

Ocean acidification is the process by which CO2 is absorbed by seawater, leading to a decrease in pH and making the ocean more acidic.

Front

What is the main use of fossil fuels?

Back

The main use of fossil fuels is to produce electricity through the thermal energy they contain.

Front

Which gas is NOT a greenhouse gas?

Back

Oxygen is not a greenhouse gas; carbon dioxide, methane, and water vapor are.

Front

What is deforestation?

Back

Deforestation is the clearing or thinning of forests by humans, which can lead to increased carbon dioxide levels in the atmosphere.

Front

What is the impact of reduced vegetation on carbon dioxide levels?

Back

Reduced vegetation leads to more carbon dioxide in the atmosphere because plants absorb CO2 during photosynthesis.

Front

What is the role of methane in climate change?

Back

Methane is a potent greenhouse gas that contributes to climate change by trapping heat in the atmosphere.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas.
