Minerals, elements and the Earth’s crust @RSC

"Almost 99% of the minerals making up the Earth’s crust are made up of just eight elements. Most of these elements are found combined with other elements as compounds. Minerals are elements or compounds that occur naturally in the Earth’s crust. Rocks are mixtures formed of minerals.

Table 1 gives some information about the most common elements in the Earth’s crust in order of abundance."
