The atmosphere of Mars became thin, which cause the water to freeze.
The water became trapped beneath the rocky surface of Mars.
The atmosphere of Mars became thin, allowing the Sun to "bake" the surface and boil off the water.
There was never liquid water on Mars, and many of the evidence suggesting water once flowed was caused by Mars' strong winds.
