Climate change

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

Name a greenhouse gas that occurs naturally in the atmosphere.

Back

Water vapor is a naturally occurring greenhouse gas.

Front

What role do water vapor and carbon dioxide play in climate change?

Back

Both water vapor and carbon dioxide are greenhouse gases that contribute to the greenhouse effect, leading to global warming and climate change.

Front

What is a natural source of greenhouse gases?

Back

Volcanic eruptions release greenhouse gases into the atmosphere.

Front

How do ice cores provide evidence for climate change?

Back

Ice cores contain trapped air bubbles that preserve historical levels of greenhouse gases, such as carbon dioxide, allowing scientists to study past climate conditions.

Front

True or False: Methane is a greenhouse gas.

Back

True

Front

What would happen to Earth without the greenhouse effect?

Back

Without the greenhouse effect, Earth would be too cold to support most forms of life.

Front

What is the primary human activity that increases carbon dioxide levels in the atmosphere?

Back

Burning fossil fuels for energy is the primary human activity that increases carbon dioxide levels.

Front

What is deforestation and how does it relate to climate change?

Back

Deforestation is the clearing of forests, which reduces the number of trees that can absorb carbon dioxide, contributing to increased greenhouse gas levels.

Front

What is the significance of aerosols in the atmosphere?

Back

Aerosols can affect climate by reflecting sunlight away from Earth and influencing cloud formation.
