Question Solved1 Answer 5. Explain or sketch how silicon-oxygen tetrahedra can join in five different geometries to produce five silicate mineral groups. 6. Describe the main light- and dark-colored silicate minerals, in terms of their chemical composition and density. 7. Select from the list you made in question 3, identify the most common class of minerals in the crust, mantle, and inner core. 8. List the three most abundant elements in the crust and in Earth as a whole and explain why silicate minerals are so abundant in the crust and mantle.
