Humans have fertilizers, animal and sewage runoff get lots of phosphate into waters. Soaps have phosphates. Clearcutting and erosion increases loss of phosphate from land, stays in oceans. Hydrological cycle is movement of water among land, ocean, atmosphere. Water leaves atmosphere as precipitation over land or ocean Evaporates from ocean surface, lakes, streams, etc.
Water also seeps through soil to groundwater, which is in layers of rock called aquifers.
Humans pump water out, can cause aquifer depletion. Glaciers keep water in ice out of circulation thousands of years. Global atmospheric circulation is driven by sun s differential warming. Hot air rises at equator, moves away, cools and sinks. Horizontal movements are winds Coriolis effect is deflection of winds by Earth s rotation, deflected to right in Northern Hemisphere, left in Southern.
