Future of Earth and Venus: A Cosmic Perspective

What is the habitable zone?

• A region where only gas giants can exist

• A region where conditions are just right for liquid water

• A region where planets are too cold for life

• A region where planets are too hot for life

Why is Venus hotter than Mercury despite being further from the Sun?

• Venus has more volcanic activity

• Venus has a larger size than Mercury

• Venus is closer to the Sun than Mercury

• Venus has a thicker atmosphere that traps heat

What did the Venus Express probe discover about Venus's atmosphere?

• It has no greenhouse gases

• It has a lot of oxygen

• It is composed mostly of nitrogen

• It contains a heavy form of hydrogen indicating past water

What is expected to happen to Earth's temperatures over the next two billion years?

• They will decrease significantly

• They will remain stable

• They will increase dramatically

• They will fluctuate unpredictably

How might animals adapt to the hotter summers in the future?

• By becoming nocturnal

• By hibernating during the summer

• By developing thicker fur

• By migrating to colder regions

What is a potential consequence of the greenhouse effect on Earth in less than a billion years?

• Earth will have a stable climate

• Earth will become a frozen wasteland

• Earth will become a parched desert

• Earth will develop a new atmosphere

What might happen to large warm-blooded animals like bison as temperatures rise?

• They will migrate to the poles
