Titan's Atmosphere:
* Nitrogen (N2): This is the dominant gas, making up about 95% of Titan's atmosphere.
* Methane (CH4): This is a significant component, accounting for about 5% of the atmosphere. It's responsible for the hazy orange color and contributes to the formation of clouds and rain.
* Water vapor (H2O): Water vapor exists in Titan's atmosphere but is extremely scarce compared to nitrogen and methane. It is found mainly in the upper atmosphere.
Titan's Surface:
* Ice: Titan's surface is primarily composed of water ice, which is mixed with various other ices like methane, ethane, and ammonia.
* Rock: There's also a rocky core beneath the ice.
Key Points:
* Methane and water vapor are present, but not the main components.
* Nitrogen is the dominant atmospheric gas.
* Water ice is a major component of Titan's surface.
In Summary: Titan's atmosphere is mostly nitrogen, with methane being a significant constituent. Its surface is mostly made of water ice. Water vapor is present in the atmosphere but in very small amounts.
