What is the approximate contribution of mica in the formation of the earth's crust?

Correct option is C

The correct answer is (c) 4%.
Mica is a group of silicate minerals that are important components of the Earth's crust. It forms a significant part of metamorphic, igneous, and sedimentary rocks. However, its contribution in the formation of the Earth's crust is relatively small compared to other minerals like feldspar and quartz.
· Mica constitutes approximately 4% of the Earth's crust.
· It is known for its unique physical properties, such as its ability to be split into thin, transparent sheets.
· Mica is widely used in industrial applications, especially in electronics, due to its insulating properties.
Information Booster:
· Mica is classified into different types, with muscovite and biotite being the most common.
· The flaky and elastic nature of mica is due to its crystal structure.
· Mica is a common mineral found in granites and other metamorphic rocks.
· It is an excellent insulator and is used in the production of electrical equipment.
· India is one of the largest producers of mica globally.
