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
Silicates are the most widespread of the minerals. They are made up of oxygen and silicon the number one and number two most abundant elements in the earth's crust.By themselves they make up over 90% of the weight of the earthâs crust. Most rocks are composed mainly of this class of minerals.ilicates are the most widespread of the minerals.
