ICSE Geography Class 10 Question Bank Chapter 8 Mineral and Energy Resources 1
Questions Based on Minerals Resources
Question 1.
What is a mineral? State two characteristic of minerals.
Answer:
Minerals are natural substances of organic or inorganic origin
with definite chemical and physical properties.
Characteristics of minerals;
- Minerals are not evenly distributed over space.
- Minerals have inverse relationship in quality and quantity, i. e. good quality minerals are less in quantity than low quality minerals.
- Minerals are exhaustible over time. They take long time to develop geologically and cannot be replenished immediately when needed.
Question 2.
Name two uses of iron ore.
Answer:
(i) About 90 percent of iron-ore is used to make steel. Raw iron by itself is not as strong and hard as needed for construction and other purposes. So it is alloyed with other elements to strengthen and harden it, making it useful for construction, automobiles and other forms of transportation such as trucks, trains and train-tracks.
(ii) Powered iron is used in manufacturing metallurgy products, magnets, high frequency cores, auto-parts and catalysts.
(iii) Radioactive iron (iron is 59 per cent) is used in medicine as tracer element and in biochemical and metallurgical research.
Question 3.
Name two varieties of Iron ore used in industry.

III. Structured Questions
Question 2.
(a) Write a brief note on the distribution of iron ore in India.
Answer:
India ranks ninth among the iron-producing countries. It has about 6.6% iron ore reserves of the world. Iron ore in Indian subcontinent is distributed as given below:
(i) India:
Many Indian States have rich deposits of iron ore.
(1) Orissa:
Orissa produces about one-third of the total iron ore production in India. These ores are found in the districts of Mayurbhanj, Keonjhar, Sundargarh, Cuttack, and Koraput etc. The ores found in this region are good quality haematite.
(2) Jharkhand:
Jharkhand is the second-largest iron producer in India. The main iron ore producing districts are Singhbhum and Palamau.
(3) Karnataka:
Karnataka is the fifth major iron ore producer in India. It has huge reserves of haematite and Magnetite. The main deposits of iron ore found in Karnataka are at Kemmangundi and Baba Budam Hills in Chikmagalur district, Hospet and Sandur in Bellary district and also Kudremukh.
(4) Chhattisgarh:
In Chhattisgarh, iron ore is mainly found in Bastar and Durg districts. Bailadila in Bastar district produces good quality of haemetite ore.
(5) Maharashtra:
The main deposits ofiron ore are found in the region of Lohara Hills in Chanda district. Other low grade deposits are found in the districts of Raigarh, Ratnagiri, Satara and Bhandara.
(6) Andhra Pradesh:
Mainly magnetite ore is found in Andhra Pradesh in the districts of Cuddapah and Chabali.
(7) Tamil Nadu:
In Tamil Nadu, Iron ore is found in Tiruchirapalli and Salem districts.
(8) Goa:
The Iron ore deposits are found at Kudriem, Bicholim, Ponda, Sanguem, Satari, Sahqualim Pali and Sirigao. Betawisgivenabrief account of the deposits and the concerning locations of Iron ore in the neighbouring countries of India, from which a clear picture can be easily depicted of reserves of Iron ore throughout the subcontinent.
(b) Name the two belts where manganese is found in India.
Answer:
Andhra Pradesh, Madhya Pradesh.
(c) Mention the three varieties of Iron ore found in India? Briefly explain the features of the Iron ore deposits in India.
Answer:
Three varieties of Iron ore found in India are :
- Haematite :
It is reddish in colour and is also known as ‘Red Ore’. It contains 60 to 70 per cent pure Iron and is found in Odisha, Jharkhand, Chhattisgarh, Karnataka and Maharashtra. - Magnetite :
It is dark brown to blackish in colour and is, therefore, known as ‘Black Ore’. It is the best quality of Iron and contains more than 70 per cent of Iron. Since it possesses magnetic property, it is called magnetite. It is found in Tamil Nadu and Karnataka. - Limonite :
It is yellow or light brown in colour and contains 35 to 50 per cent of Iron. It occurs in the Iron stone group in the Raniganj coalfield. It is also found in Garhwal (Uttarakhand) and Mirzapur district (UP) and the Kangra Valley (Himachal Pradesh).
Features of the Iron ore deposits in India :
The Iron ore deposits in India are found in close proximity to the areas producing coal, dolomite, limestone and manganese. Therefore they are well-utilised in several Iron and steel plants. In Jharkhand and Odisha, die Iron ore deposits are found in the close vicinity of coal fields and have a low sulphur content. Another significant feature of these deposits is that they occur as hill masses and are easily accessible.
(d) Which state is the leading producer of manganese? What are the uses of manganese?
Answer:
Maharashtra is the leading producer of manganese.
Manganese is a ferro-alloy used in making steel.
