Wave shoaling is the process when surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling, and the waves are said to shoal.n a nautical sense, a bar is a shoal, similar to a reef: a shallow formation of (usually) sand that is a navigation or grounding hazard, with a depth of water of 6 fathoms (11 metres) or less. It therefore applies to a silt accumulation that shallows the entrance to or course of a river, or creek.
Phosphorus (P) Phosphorus (P), phosphorusnonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
Phosphorus is another one of those elements that you will never find free in nature. It is very reactive. When isolated and pure, phosphorus is clear and almost transparent. There are four common forms of phosphorous used today: white, black, red, and violet. It's easy to spot phosphorus on the periodic table just under nitrogen (N) at position number fifteen. You can find phosphorus in baking powder, fertilizers, and fireworks. > More about the orbitals and compounds of phosphorus.
