Question 1

True or false: Titan’s atmosphere is mostly nitrogen, like Earth’s, but much thicker and colder.

Accepted Answer

True. At 95% nitrogen, Titan’s atmosphere is the densest of any moon in the solar system, with surface pressure 1.5 times Earth’s.

Question 2

True or false: Titan’s surface temperature is warm enough for liquid water to flow freely.

Accepted Answer

False. Titan’s surface is a frigid -179°C (-290°F), far too cold for liquid water. Methane and ethane are liquid at those temperatures.

Question 3

True or false: Titan was discovered by Galileo in 1610, the same year he found Jupiter’s largest moons.

Accepted Answer

False. Galileo discovered Jupiter’s moons. Titan was discovered in 1655 by Christiaan Huygens, orbiting Saturn.

Question 4

True or false: Titan is the only moon in the solar system with a substantial atmosphere.

Accepted Answer

True. Titan's atmosphere is dense, with surface pressure 1.5 times Earth's. Other moons like Triton and Io have only extremely tenuous atmospheres, not substantial.

Question 5

True or false: Titan has a methane cycle similar to Earth's water cycle, with rain and liquid lakes.

Accepted Answer

True. Titan is the only other world with stable liquid on its surface—methane forms clouds, rain, and vast lakes, just like water on Earth.

Question 6

True or false: Titan’s orange haze is caused by volcanic eruptions spewing sulfur compounds.

Accepted Answer

False. The haze comes from methane photochemistry—sunlight breaks methane into organic particles called tholins, creating the orange smog.

Question 7

True or false: Scientists have confirmed liquid water oceans exist beneath Titan’s icy crust.

Accepted Answer

True. Data from Cassini revealed a subsurface ocean of liquid water and ammonia, making Titan a prime candidate for potential alien life.

Question 8

True or false: Titan’s dunes are made of solid ice grains blown by wind, not sand.

Accepted Answer

False. Titan’s dark equatorial dunes are actually composed of hydrocarbon and nitrile particles, not ice grains. They resemble frozen soot, not sand.
