potassium is formed in supernovae by nucleosynthesis from lighter atoms. potassium is principally created in type ii supernovae via an explosive oxygen-burning process. is also formed in s-process nucleosynthesis and the neon burning process.









































potassium is the 20th most abundant element in the solar system and the 17th most abundant element by weight in the earth. it makes up about 2.6% of the weight of the earth's crust and is the seventh most abundant element in the crust. the potassium concentration in seawater is 0.39g/l (0.039 wt/v%), about one twenty-seventh the concentration of sodium.

earth crust displacement









































earth crustal displacement or earth crust displacement may refer to: 









































bullet::::- plate tectonics, scientific theory which describes the large scale motions of earth's crust (lithosphere).









































bullet::::- fault (geology), fracture in earth's crust where one side moves with respect to the other side.









































bullet::::- supercontinent cycle, the quasi-periodic aggregation and dispersal of earth's continental crust.









































bullet::::- cataclysmic pole shift hypothesis, where the axis of rotation of a planet may have shifted or the crust may have shifted dramatically.
