A nother way to study the solar system is to actually go there on a trip called a crewed mission. A space shuttle can bring astronauts and their tools into space to perform experiments, launch satellites, and make observations.
by far the largest chemical group This group of minerals contains SiO44- as the dominant polyanion. In these minerals the Si4+ cation is always surrounded by 4 oxygens in the form of a tetrahedron. Because Si and O are the most abundant elements in the Earth, this is the largest group of minerals and is divided into subgroups based on the degree of polymerization of the SiO4 tetrahedra. rock-forming minerals
Scientific Classifications of Mineral Groups. Scientific Classification. **Minerals and gemstones are classified according to their chemical compositions. There are eight classes, along with a ninth class for non-minerals, which may be non-crystalline organic combinations and/or rocks.The nine classes are listed below with examples of a few of the individual species within these groups. group of minerals that are compounds of one or more metallic elements associated with the Phosphate radical. They are classified together with the Arsenates and Vanadates. They are usually brittle and occur in small crystals or compact aggregates.
