What is phosphorus

What do we need phosphorus for? It natural use Formation of bone/ teeth ATP (adenosine triphosphate) Human uses Fertilizers & detergent matches White phosphorus

Too much of a good thing? Natural To much phosphorus in people = kidney damage and osteoporosis A lack of phosphorus limits algae growth. High phosphorus fertilizers = ?

Artificial eutrophication

Weathering versus geologic uplift Weathering: Breakdown of rock into smaller pieces –Chemical weathering: acid rain, Lichens –Physical weathering: wind, rain, freezing,

Geologic uplift The process of building mountains. The earths crust folds up exposing phosphorus rock

Parts of the Phosphorus Cycle Phosphorus Flows: The amount of phosphorus that moves in or out of that source (circles)

Parts of the Phosphorus Cycle Phosphorus Flows: The amount of phosphorus that moves in or out of that source (circles) Stored Phosphorus: amount of millions of tonnes phosphorus stored in that source (squares)
