Life is thought to be unlikely in subsurface oceans, such as those in Europa, because sunlightdoes not reach these oceans.

Question

Quizplus · Accepted Answer

Life is thought to be possible in subsurface oceans because they can still have sources of energy from geothermal activity and potentially even chemical reactions. While sunlight may not reach subsurface oceans, there are a number of other potential energy sources, such as hydrothermal vents, that could support life. Additionally, some organisms on Earth are able to survive in extreme environments and may have adapted to similar conditions in subsurface oceans. Therefore, life may be possible in these environments.
