Intro to Climate Change

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.

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide, methane, and water vapor.

Front

Which gas is not a greenhouse gas?

Back

Oxygen is not a greenhouse gas.

Front

How does carbon dioxide affect global temperatures?

Back

Carbon dioxide traps heat in the atmosphere, contributing to the greenhouse effect and increasing global temperatures.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat from the sun in the Earth's atmosphere, keeping the planet warm.

Front

Why are greenhouse gases important for life on Earth?

Back

Greenhouse gases are important because they help maintain the Earth's temperature, making it suitable for life.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the average weather over a long period.

Front

What is one solution to decrease global temperatures?

Back

Using more biofuels is one solution to decrease global temperatures.

Front

What has increased at the same rate as global temperatures over the past 100 years?

Back

Carbon dioxide levels have increased at about the same rate as global temperatures.

Front

What role do trees play in climate change?

Back

Trees absorb carbon dioxide, helping to reduce greenhouse gas levels in the atmosphere.
