Question

if water caused the huge outflow channels on mars, what was the most likely process that formed them? a) rainfall from the hydrosphere b) catastrophic but rare flooding

Answer 1

The most likely process that formed the huge outflow channels on Mars is catastrophic but rare flooding. There is evidence of large-scale flooding on Mars, such as the outflow channels that are hundreds of kilometers long and tens of kilometers wide, which are thought to have been caused by catastrophic floods that occurred billions of years ago. Rainfall is not likely to have been the cause, as the Martian atmosphere is too thin to support rainfall as it occurs on Earth.
