The hydrologic cycle is the path of what substance?

The correct answer is water.  

The hydrologic cycle refers to the sequence of conditions via which water mediates from vapor in the atmosphere via precipitation upon water surfaces or land and eventually back into the atmosphere as an outcome of transpiration and evaporation. This is also known as a hydrological cycle.  

The prime constituents of the hydrologic cycle are an interception, precipitation, evaporation, depression storage, infiltration, and transpiration, moisture storage in the unsaturated zone, percolation, and runoff.
