5.4 Causes of Climate Change: Natural and Anthropogenic

Open Ended

Think about it...

What do you believe could be causing climate change?

Multiple Choice

Suppose a major volcanic eruption occurred, releasing a large amount of ash and sulfur dioxide into the atmosphere. How might this event impact global temperatures?

• Global temperatures would decrease because ash and sulfur dioxide reflect sunlight away from Earth's surface.

• Global temperatures would increase because ash and sulfur dioxide trap heat in the atmosphere.

• Global temperatures would increase and then decrease because ash and sulfur dioxide initially trap heat in the atmosphere but eventually settle out.

Multiple Choice

Agricultural practices in a particular region involve large-scale deforestation to create more land for crop cultivation. How does deforestation for agricultural purposes contribute to climate change in this scenario?

• Deforestation has no significant impact on climate change.

• Deforestation increases carbon dioxide (CO₂) levels in the atmosphere, contributing to climate change.

• Deforestation enhances the absorption of greenhouse gases, mitigating climate change.
