The Transfer of Water in Martian History
On Mars, the water is trapped, frozen, within the ground. Nevertheless, there is evidence for running water on Mars.
When the water is melted and released to the surface, it will run from higher ground to lower ground.
Because this water transfer can only take place when the water melts, however, the water transfer takes a very long time.
