Calcium strontium or barium, the oxide–nitride coating that results in air is stable and lathe machining and other standard metallurgical techniques are suitable for calcium. In the United States and Canada, calcium is instead produced by reducing lime with aluminium at high temperatures. Calcium provides a link between tectonics, climate, and the carbon cycle. In the simplest terms, uplift of mountains exposes calcium-bearing rocks to chemical weathering and releases Ca into surface water. These ions are transported to the ocean where they react with dissolved CO to form limestone (), which in turn settles to the sea floor where it is
Society for Scientific Exploration Society for Scientific Exploration The Society for Scientific Exploration, or SSE, is a group committed to studying fringe science. The opinions of the organization in regard to what are the proper limits of scientific exploration are often at odds with those of mainstream science. Critics argue that the SSE is devoted to disreputable ideas far outside the scientific mainstream. The Society was founded in 1982. Its first meeting took place at the University of Maryland, College Park in 1982. Of the SSE and its journal, journalist Michael D..
