The Impact of Climate Change on Earth's Systems and Biodiversity

The video explains the difference between global warming and climate change, focusing on the greenhouse effect caused by gases like carbon dioxide and methane. Human activities such as burning fossil fuels and deforestation increase these gases, leading to global warming. The video discusses the consequences, including climate change, sea level rise, and biodiversity loss, and concludes with a call to action.

What is the primary function of Earth's atmosphere in relation to temperature?

• To absorb all heat from the sun

• To cool the Earth by reflecting sunlight

• To act as a greenhouse, maintaining a stable temperature

• To block all solar radiation

How does the greenhouse effect keep the Earth warm?

• By allowing all heat to escape into space

• By trapping heat energy through repeated absorption and re-emission by gas particles

• By absorbing all sunlight directly

• By reflecting sunlight back into space

Which gases are primarily responsible for the greenhouse effect?

• Carbon dioxide, methane, and water vapor

• Oxygen and nitrogen

• Argon and krypton

• Helium and neon

What human activity is a major contributor to the increase in carbon dioxide levels?

• Using solar panels

• Recycling waste

• Burning fossil fuels

• Planting more trees

How does deforestation contribute to global warming?

• By cooling the Earth's surface

• By reducing the process of photosynthesis that removes carbon dioxide

• By increasing the number of animals

• By increasing oxygen levels

What is one of the predicted consequences of global warming on weather patterns?

• Decrease in rainfall

• More frequent and severe weather events

• Stable weather conditions

• Less severe hurricanes

What are the two main reasons for rising sea levels?

• Increased volcanic activity and earthquakes

• Decreased evaporation and increased precipitation

• Melting ice and thermal expansion of seawater

• Increased rainfall and river flow

What is the term used to describe the long-term effects of global warming on the planet's climate?

• Weather change

• Climate change

• Seasonal variation

• Atmospheric shift

How might climate change affect biodiversity?

• Biodiversity will increase as new species emerge

• All species will easily adapt to new conditions

• Species may struggle to adapt or migrate, leading to reduced biodiversity

• Species will thrive in their current habitats

What happens to species that cannot adapt or migrate due to climate change?

• They may face extinction

• They move to urban areas

• They evolve rapidly

• They become more resilient
