What is the primary component of the Earth's crust made from various minerals?

The primary component of the Earth's crust is indeed rock, as it encompasses a variety of minerals that make up different rock types. The Earth's crust is formed above the mantle and consists mainly of igneous, metamorphic, and sedimentary rocks, which are composed of various mineral assemblages.

Granite, a specific type of igneous rock, is primarily composed of quartz, feldspar, and mica, making it an example of a rock rather than the general category. Soil, while important, is a mixture of organic matter, minerals, gases, liquids, and countless organisms, and is not a direct component of the crust itself. Minerals are the building blocks of rocks, existing within them and contributing to their composition. However, when we talk about the primary component in regards to the Earth's crust, it refers to the rock itself, which houses these minerals.
