Climate Change and Its Effects

What are greenhouse gases?

• Gases that cool the Earth's surface

• Gases that trap heat in Earth's atmosphere

• Gases that are only found in greenhouses

• Gases that are used in refrigeration

What is a major part of climate change?

• Global cooling

• Global warming

• Ocean freezing

• Atmospheric thinning

What human activities contribute to the increase in greenhouse gases?

• Planting trees

• Burning fossil fuels

• Recycling

• Using solar panels

What is the role of carbon dioxide in ocean acidification?

• It decreases ocean salinity

• It increases ocean pH

• It causes the absorption of excess CO2

• It stabilizes ocean temperature

How do human activities intensify the greenhouse effect?

• By reducing CO2 levels

• By adding more greenhouse gases to the atmosphere

• By increasing ocean acidity

• By cutting down on fossil fuel use

What happens to oceans as they absorb more heat from the atmosphere?

• They become cooler

• They warm up

• They become less acidic

• They increase CO2 absorption

How does ocean warming affect marine life?

• It has no effect

• It harms marine life

• It cools marine habitats

• It reduces sea level rise

What happens to oceans as they absorb more CO2?

• They become less acidic

• They become more acidic

• They remain neutral

• They become more alkaline

What is the role of graphs in studying climate change?

• To show short-term variations

• To visualize temperature and CO2 trends over time

• To predict future weather patterns

• To measure ocean acidity

What would happen to Earth without the greenhouse effect?

• It would be too hot to support life

• It would be too cold to support life

• It would have no change

• It would become more acidic
