Over millions of years, much of this water is recycled between the inner Earth, the oceans and rivers, and the atmosphere. This cycling process means that freshwater is constantly made available to Earth's surface where we all live. Volcanoes release massive amounts of water from the inner Earth to the atmosphere.
There is absolutely nothing weird about a river flowing north. Rivers flow in one direction all over the world, and that direction is downhill. Across the central and eastern United States, it is rare for rivers to flow north because the slope of the land is toward the south and east.
