Final answer:
Large methane lakes exist near Titan's polar regions, and these lakes interact with the atmosphere in a cycle similar to Earth's water cycle.
Step-by-step explanation:
Titan contains liquid methane and ethane lakes in its polar region.
Imaging of Titan's surface by the Cassini orbiter has revealed large methane lakes near the polar regions. These lakes are part of a hydrological cycle involving methane rain and erosional features similar to those on Earth, except the liquid involved is not water but methane, ethane, and other hydrocarbons. The lakes and rivers on Titan are the result of a low-temperature cycle that evaporates liquid on the surface, forming clouds that condense and fall as rain, analogous to Earth's water cycle. However, the composition of these liquids and the temperature of the environment make Titan's surface a familiar yet completely alien landscape compared to Earth.
Titan contains liquid methane lakes in its polar region. These lakes interact with the methane in the atmosphere, similar to how Earth's water oceans interact with water vapor. The presence of erosional features indicates that atmospheric methane can condense and fall as rain, then flow down valleys to the lakes, creating a low-temperature equivalent of the water cycle on Earth.
