Review of Climate Change

Front

What is the Air Quality Index (AQI)?

Back

The Air Quality Index (AQI) is a number used by government agencies to communicate how polluted the air currently is or how polluted it is forecast to become.

Front

What is the main human activity that contributes to climate change?

Back

The main human activity that releases greenhouse gases is burning fossil fuels, such as coal, oil, and natural gas.

Front

What occurs during La Niña?

Back

During La Niña, trade winds strengthen and warm surface water moves eastward across the Pacific Ocean.

Front

How do carbon dioxide levels affect Earth's temperature?

Back

Higher carbon dioxide levels mean more heat is retained in Earth's atmosphere, leading to an increase in global temperatures.

Front

What does an AQI of 210 indicate?

Back

An AQI of 210 indicates that it is dangerous for all people to spend a lot of time outside.

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 (CO2), methane (CH4), and nitrous oxide (N2O).

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 into space and thus warming the planet.

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.

Front

What role do trees play in combating climate change?

Back

Trees absorb carbon dioxide from the atmosphere, helping to reduce greenhouse gas levels and mitigate climate change.

Front

What is the difference between weather and climate?

Back

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