Evidence of Running Water
Evidence such as this for running water on Mars is abundant. But this evidence suggests that the nature of flowing water on Mars is nothing like it's counterpart on Earth. The evidence is in the form of:
- 1.) large, tear-dropped shaped outflow channels
- 2.) river valley networks unlike river valleys of Earth
- 3.) catastrophic floods
