Minerals in India - Concepts - Chapter 5 Class 10 Geography - Minerals and Energy Resources - Geography

Minerals in India :

• India is fortunate to have fairly rich and varied mineral resources.
• Peninsular rocks contain most reserves of coal, metallic minerals, mica and many other non metallic minerals.
• In Gujarat and Assam , peninsular deposits have most petroleum deposits.
• Rajasthan peninsular rocks have reserves of many non ferrous minerals .
• The concentration of mineral in the ore , the ease of extraction and closeness to the market play an important role in affecting the viability of the reserve.

BRIGHT SMILE FROM TOOTHPASTE AND MINERALS :

What does a toothpaste consist of?

1. Toothpaste cleans your teeth.
2. Abrasive minerals like silica, limestone, aluminium oxide and various phosphate minerals do the cleaning.
3. Fluoride , used to reduce cavities, comes from a mineral fluorite.
4. Most toothpastes are made from white titanium oxide , which comes from minerals like rutile, ilmenite and anatese.
5. Sparkle in toothpaste comes from mica.
6. Toothbrush and tube containing the paste are made from plastic.

ALL LIVING THINGS NEED MINERALS :

• Life processes can’t occur without minerals.
• Our mineral intake represents only about 0.3% of our total intake of nutrients.
• They are very potent and so important that without them we won’t be able to utilize the 99.7% foodstuff.

Geographers and Geologists :

• Geographers study minerals as part of the earth’s crust for a better understanding of landforms. Distribution of mineral resources and associated economic activities are of interest to geographers.
• Geologists are interested in the formation of minerals, their age and physical chemical composition.
