Water's Creations

The harsh climates on Mars make it impossible for water to be on the surface, but before the water left it created channels and craters.  The biggest canyon on Mars is about the size of the United States. This canyon was probably created by water.  Another thing created by water were lakes.  These lakes look a lot like craters on the surface of Mars.  Channels were also created by water.  Channels are stream-like lines, they're created by water rushing through them over the years.  Mars' water created a lot of things before it disappeared.
