Which planet thought to have liquid water in the past?
Mars is the planet thought to have had liquid water in the past based on various geological features such as canyons, river valleys, and mineral signatures found on the surface. These suggest that Mars likely had a more hospitable environment billions of years ago where liquid water could have existed.
What evidence suggests that liquid water is or once was present on mars?
There is evidence that there was once water on Mars due to large gullies on its surface. This may suggest that running liquid water may have eroded it away and the fact that Mars has 'frozen' ice caps may suggest that it was once liquid water that had frozen over a large period of time.
