Which correct information from the text about Titan?Titan is the largest among all moons in solar system  blankTitan and Enceladus are more habitable than Saturn  blankTitan is more habitable because it has thick atmosphere and liquid on its surface  blankScientific instruments can see clearly the surface features of Titan  blank     √           Χ

Of Saturn’s 62 moons, the two most habitable for human life are Titan and Enceladus. They are very different from each other. For example, Titan is the second largest moon in our solar system, with a diameter of 2,575 kilometers. Tiny Enceladus has a diameter of only 500 kilometers. The atmosphere on Titan is thick and hazy, hiding surface features from most scientific instruments. Only its seasonal storms are visible. In contrast, the atmosphere on Enceladus is very thin. This means there is no air pressure or weather. However, scientists are better able to see what’s happening on its surface. Each of the moons  has a unique feature, as well. Titan is the only other place we know of in our solar system with liquids flowing across its surface. Enceladus doesn’t have liquids flowing on the surface, but there are geysers sending icy particles and water vapor into the sky at a speed of nearly 1,300 kilometers per hour.Which correct information from the text about Titan?Titan is the largest among all moons in solar system  blankTitan and Enceladus are more habitable than Saturn  blankTitan is more habitable because it has thick atmosphere and liquid on its surface  blankScientific instruments can see clearly the surface features of Titan  blank     √           Χ

3.Question 3Which of the following is not a viable argument against the possibility that there is some sort of life on Titan?1 pointLiquid methane is non-polar and thus would be non-ideal for life.Titan has such a thick haze layer that the amount of sunlight reaching the surface provides little energy.If life existed on Titan, it should leave a detectable signal in the atmosphere.Liquid water probably exists under the icy surface of Titan, but it is unlikely to be in contact with rock, and thus unlikely to have sustainable sources of energy and nutrients.Pools of liquid water that might transiently exist after impacts don't survive long enough for water-based life to develop.Temperatures on Titan are so cold that chemical reactions would be too slow for organisms to evolve and thrive.

Which object in the solar system is of interest to scientists because of its thick atmosphere and lakes of methane on its surface?Group of answer choicesTitanEuropaIoEnceladus

he Earth's atmosphere is 78% nitrogen and its surface can clearly be seen from space. In comparison, Titan's atmosphere is composed of 97% nitrogen, with a small amount of methane and trace amounts of other molecules. However, the surface of Titan is obscured from view in visible light with a thick orange smog. Briefly explain what gives rise to this smog and how this is linked to the dark features observed near the north pole.
