Answer to Question 1

Like the Earth's, Titan's atmosphere is made chiefly of nitrogen, and it is at about the same barometric pressure as the Earth's at both surfaces. However, it is much colder, it lacks any substantial oxygen, and its clouds are made of methane and other hydrocarbons, not water droplets like ours.
