Answer to Question 1

The Mohs hardness scale measures a mineral's resistance to abrasion and is controlled mostly by its
internal structure. The minerals of the scale from softest to hardest are: talc, gypsum, calcite, fluorite,
apatite, orthoclase/feldspar, quartz, topaz, corundum, and diamond.



Answer to Question 2

All silicate minerals contain silica, which is made of one silicon and oxygen. Silicate minerals include
about one-third of all minerals; together they make up 95 of Earth's crust.
