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 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

How does global warming affect sea levels?

Back

Global warming causes sea levels to rise primarily by melting glaciers and ice caps.

Front

What is one effect of global warming on weather patterns?

Back

Global warming can lead to more extreme weather patterns, including increased frequency of droughts and heavy rainfall.

Front

What is the role of deforestation in global warming?

Back

Deforestation contributes to global warming by reducing the number of trees that can absorb CO2 from the atmosphere.

Front

What is the significance of the polar ice caps?

Back

The polar ice caps are crucial for regulating Earth's temperature and sea levels; their melting contributes to rising sea levels.

Front

What can individuals do to help reduce global warming?

Back

Individuals can reduce global warming by conserving energy, using public transport, recycling, and turning off lights when not in use.

Front

What is the relationship between fossil fuels and greenhouse gases?

Back

Burning fossil fuels releases significant amounts of greenhouse gases into the atmosphere, contributing to global warming.

Front

What is an example of a renewable energy source?

Back

Examples of renewable energy sources include solar energy, wind energy, and hydroelectric power.
