Home Calibri (Body) 12 · A-Ar A. , A' ' BIU abe X2 x AA Paragraph Styles 12 pts] Two planets A and B are the same distance from the Sun. Which planet will have a higher global-average surface temperature if planet A has an atmosphere containing an appreciable amount of carbon dioxide gas, and planet 8 has no atmosphere. Explain your answer in 2-3 complete sentences. 5. Sc Al St Lo Vi Po [2 Rt Lome astronomers have speculated that the carbon-silicon cycle is essential for habitability of Earth and other similar worlds. What does this cycle regulate, and why would it be important for sustaining life? Write your answer in 4-5 complete sentences. 6 Page 1 of 3 505 Words --+ 100% esc FI F4 F6

Explanation / Answer

7.The planet A haveve high global average surface temperature because without CO2 there will be no greenhouse effect and without greenhouse effect the average surface temperature will be -18 0C
So, A will be with more temperature

8. The carbon-silicon rocks regulates the amount of heat in the atmosphere. This is important because with increase in CO2 content over the silicon the temperature of planet increases and ice is converted into water and vice versa happens when silicate concentration increases over the CO2 concentration. This is because silicates consume the CO2 and temperature drops.
