GEOLOGY

Detailed explanation-1: -More than 90% of the Earth’s crust is composed of silicate minerals, making silicon the second most abundant element in the Earth’s crust. Silicon links up with oxygen to form the most common minerals on Earth.

Detailed explanation-2: -The most abundant elements in the Earth’s crust are oxygen (46.6%) and silicon (27.7%). Minerals which combine these two elements are called silicates, and combined they are the most abundant minerals on the Earth.

Detailed explanation-3: -Feldspars are the most abundant mineral group on Earth and make up nearly 60% of Earth’s crust. Feldspars are used in glassmaking, ceramics, as fillers in paints, and in plastics and rubber. Hematite is the principal ore of iron.

Detailed explanation-4: -Silicates are by far the most common minerals in Earth’s crust and mantle, making up 95% of the crust and 97% of the mantle by most estimates.

Detailed explanation-5: -The most common mineral in absolute is Bridgmanite, known also as Silicate-Perovskite. It´s composed of magnesium, iron and silicon dioxide and it’s estimated to make up 38% of earth’s volume.
