Which minerals would be considered one of the eight to ten rock-forming minerals? quartz and feldspar mica and olivine copper and silver garnet and calcite

## Step 1<br />The problem asks us to identify which minerals among the given options are considered one of the eight to ten rock-forming minerals. These minerals are the primary constituents of rocks and are commonly found in the Earth's crust.<br /><br />## Step 2<br />The eight to ten rock-forming minerals typically include quartz, feldspar, mica, amphibole, pyroxene, olivine, calcite, and dolomite.<br /><br />## Step 3<br />Looking at the options, we can see that quartz and feldspar are among the rock-forming minerals. Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms, while feldspar is a group of rock-forming minerals that make up about 60% of the Earth's crust.<br /><br />## Step 4<br />The other options, such as mica and olivine, copper and silver, and garnet and calcite, are not typically considered among the primary rock-forming minerals.
