Climate Change - Causes and Impacts

Front

What is climate change?

Back

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

Front

What is carbon dioxide?

Back

Carbon dioxide (CO2) is a colorless gas that is produced by burning fossil fuels and is a major greenhouse gas contributing to climate change.

Front

What is the greenhouse effect?

Back

The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat, keeping the planet warm enough to sustain life.

Front

What human activity contributes to an increase in carbon dioxide in the atmosphere?

Back

Agriculture contributes to an increase in carbon dioxide due to practices like deforestation and the use of fossil fuels for machinery.

Front

What is deforestation?

Back

Deforestation is the process of clearing trees from land, which can lead to increased carbon dioxide levels in the atmosphere.

Front

How does deforestation affect the carbon cycle?

Back

Deforestation increases carbon dioxide in the atmosphere because fewer trees are available to absorb CO2 during photosynthesis.

Front

What happens to glaciers and ice caps as ocean temperatures rise?

Back

As ocean temperatures rise, glaciers and ice caps are melting, contributing to rising sea levels.

Front

What is the impact of climate change on weather patterns?

Back

Climate change can lead to more extreme weather patterns, including increased frequency and intensity of storms, droughts, and heatwaves.

Front

What role do oceans play in climate change?

Back

Oceans absorb a significant amount of carbon dioxide and heat, but rising temperatures can disrupt marine ecosystems and contribute to climate change.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate, as it describes how carbon moves between the atmosphere, land, and oceans.
