question 17

Multiple Choice

Titan's thick atmosphere is believed to have been created when ultraviolet photons broke apart methane molecules,ultimately creating the observed smog-like conditions.This process,though,would likely remove all of the atmospheric methane in roughly 10 million years,yet we still see its presence today.How can this be?

• A) Cometary impacts periodically bring new methane to Titan.
• B) Ethane rains down out of the atmosphere,combines with surface rocks,and creates new methane.
• C) Infrared photons give atmospheric molecules enough energy to recombine into methane.
• D) Volcanoes on Titan periodically release new methane into the atmosphere.
