How long does the water cycle process take? I’m talking about the process from evaporation to precipitation.
The conditions vary. For example, how long would it take during the spring, in a cool state, like Virginia? It’s for a report and it doesn’t really specify.

If we tallied up all the water we have stored, outside the water cycle, in the millions of places we hold it, dams, tanks, in toilets, car radiators, refrigerators, pipes, most of the products in our supermarkets, hot water systems, etc etc, the list would be huge. How much water in total would there be in these places? (how much water is in Coke cans at the moment?)

And, hypotheticaly, if all this water was returned to the water cycle, would it have any impact on the worlds current water crisis?

Water moves from ocean to air, onto land, to lakes and streams and groundwater, back to the sky and ocean, in a continuous cycle. In the past, water was considered to be a renewable resource. Today, in many parts of the world, water has become a non-renewable resource. Discuss some ways in which humans are affecting the water cycle.

Right now the water cycle is a closed system. If hydrogen became a fuel source, how would that throw off the ecological balance of water in the environment?
Even if we recover hydrogen from water, is it a closed system or does it have leaks.
