4.Which is not true about earth when compared to Mars? a.it has life mechanism b.it has water and atmosphere c.it has carbon dioxide in the atmosphere d.it has atmosphere that supports oxygen
Answer (1)
Compared to Mars, c. it has carbon dioxide in the atmosphere is not that much true about earth.Earth has only a small amount of carbon dioxide(0.04%), while Mars has a lot more(95%). Earth’s atmosphere is mostly nitrogen and oxygen, which helps support life. So when comparing Earth to Mars, it's not true to say that Earth has carbon dioxide the way Mars does. That’s why letter c is the correct answer.
