What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities have accelerated it, particularly through the release of greenhouse gases.

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 certain gases in Earth's atmosphere trap heat, preventing it from escaping back into space, which helps to keep the planet warm.

What is the primary source of energy for electricity generation in many power plants?

Back

Coal is a primary energy source used by many power plants to generate electricity.

Front

What is the average weather for a particular time and region called?

Back

Climate is the average weather conditions in a specific area over a long period.

Front

True or False: Some greenhouse gases are naturally present in the Earth's atmosphere.

Back

True.

Front

What has caused the average temperature of the Earth's surface to increase by approximately 1°C in the past century?

Back

Higher levels of carbon dioxide in the atmosphere have contributed to the increase in Earth's average temperature.

Front

What is the role of carbon dioxide in climate change?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to global warming and climate change.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term average weather patterns in a specific area.

Front

What human activities contribute to climate change?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes release greenhouse gases into the atmosphere.
