what is the diameter of earth in km UNANSWERABLE what is the axial tilt of the planet? Approximately 23.439281° describe the internal structure of it? It is divided into layers by their chemical or physical (rheological) properties. For eg. the outer layer is a chemically distinct silicate solid crust. what is a silicate? In chemistry, it is any member of a family of anions consisting of silicon and oxygen. how is it detected? It reacts with molybdate anions yielding yellow silicomolybdate complexes. what is zeolite to it? The nature of soluble silicates is relevant to understanding biomineralization and the synthesis of aluminosilicates, such as the industrially important catalysts called zeolites. is it naturally occurring? Conventional open-pit mining techniques are used to mine natural zeolites. what is "biomineralization"? It is the process by which living organisms produce minerals, often to harden or stiffen existing tissues. mention a few of its applications? Organic macromolecules collect and transport raw materials and assemble the substrates and into short- and long-range ordered composites with consistency and uniformity. what is the relation of it with contaminating groundwater? It may be used to remediate groundwater contaminated with uranium. what are the other minerals produced from such a process? Magnetite, Goethite  and  pyrite any use of second mineral? Its main modern use is as an iron ore.

Goethite [SEP] Distribution
Goethite is found all over the planet, usually in the form of concretions, stalactitic formations, oolites (a form consisting of tiny round grains cemented together), reniform (kidney shapes) or botryoidal (globular, like bunches of grapes) accumulations. It is also a very common pseudomorph. It is frequently encountered in the swampy areas at the head of spring waters ('bog iron'), on cave floors, and on the bottom of lakes and small creeks. The "boxworks" or gossan resulting from the oxidation of sulfide ore deposits is formed of goethite along with other iron oxides and quartz. Significant deposits of goethite are found in England, Australia, Cuba, and Michigan, Minnesota, Missouri, Colorado, Alabama, Georgia, Virginia, and Tennessee, and Florida caves in the United States.
