Global Warming

Human activities affect the carbon cycle by:

• Increasing carbon dioxide emissions

• Decreasing carbon dioxide emissions

• Having no effect on carbon dioxide levels

• Balancing carbon dioxide levels

Global warming has several impacts. Which of the following is one of them?

• Rising sea levels

• Decreased air pollution

• Increased ice coverage

• Lower global temperatures

Explain why global warming happens.

What has caused the increase in the concentration of carbon dioxide in the atmosphere since 1800?

• Industrial Revolution

• Deforestation

• Increased use of fossil fuels

• All of the above

Humans add extra carbon dioxide to the atmosphere by:

• Burning fossil fuels

• Planting trees

• Using solar panels

• Recycling waste

Global warming describes how energy from the Sun is trapped by gases in the atmosphere.

• True

• False

The greenhouse effect is the term given to changes in weather patterns due to global warming.

• True

• False

Human activities increase the concentration of carbon dioxide in the atmosphere through:

• Burning fossil fuels and deforestation

• Planting trees and using renewable energy

• Recycling and reducing waste

• Using public transportation and carpooling

Which of the following are impacts of climate change on the environment?

• Rising sea levels and increased frequency of extreme weather events

• Decreased global temperatures and reduced greenhouse gas emissions

• Stabilized weather patterns and increased biodiversity

• Reduced air pollution and improved water quality

The greenhouse effect keeps the Earth warm by:

• Trapping heat in the atmosphere

• Reflecting sunlight back into space

• Absorbing ultraviolet radiation

• Increasing the Earth's albedo
