Question

lemperacure Of Terrestrial Planets l x Evcreise Planetary Data Planet a rAU 5. For the Earth to have liquid water on its surface, what range of distances from the Sun could it have? (This range of distances is called the habitable zone.) Assume the reflectivity and atmospheric composition remain at their current values. Mercury 0.12 0.39 Venus 0.75 0.72 Earth 0.30 1.00 Mars 0.16 1.52 Relative Amount . (to Earth) co2: 0.99 0.5 1.0 H20: 1.00 0.6-1.5 Predicted Temperature Hot 2013 Pearson Education, Inc. Cold 16.6 °C

Explanation / Answer

the answer is c= 0.9-1.0

If planet is too close, more evoparation of water takes place and if too far water cools down and turns into ice, so studies suggested that the inner edge of sun's habitable zone is nearly 142 million kilometers which is 0.9 au and outer edge cant exceed 1.4
