Question 2.
Answer the following questions in about 30 words.
Distinguish between the following in not more than 30 words
a) ferrous and non-ferrous minerals

Ferrous Minerals Non-ferrous Minerals

ii) What is a mineral?
A mineral can be defined as a “homogenous, naturally occurring substances with a definite internal structure.” Minerals are found in varied forms in nature, ranging from the hardest diamond to the softest talc.

iii) How are minerals formed in igneous and metamoiphic rocks?
(a) In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints.
(b) The smaller occurrences are called veins and the larger is called lodes.

ii) Why do you think that solar energy has a bright future in India ?
Solar energy has a bright future in India due to the following reasons :
(a) Solar energy is an inexhaustible source of energy that is produced from sunlight.
(b) India is a tropical country thus, there is enough scope for the development of solar energy.
(c) Many parts of the country receive sunlight at least 300 days annually and so, it becomes possible to generate 20 MW solar energy per square kilometer in such areas.
(d) It is easy to establish solar plants in urban and rural areas.
(e) By setting up solar plants in rural areas, the dependence of people on firewood can be reduced.
(f) Solar energy is also becoming popular as it is used for cooking, heating water, lighting etc.

Question 2.
Collect “Nutritional Facts” printed on food labels.
A sample of nutritional facts printed on a packet of Glucose biscuit is given below :
Food Item – Biscuit
Energy – 448.5 cal
Protein – 8.7 gm
Carbohydrates – 76.2 gm
Fats – 12.1 gm
Iron – 0.25 mg


Question 3.
What is the difference between an open pit mine, a quarry and an underground mine with shafts?
Open Pit Mine : open Pit Mining refers to a method of extracting minerals from the earth by their removal from an open pit. These mines are used when deposits of commercially useful minerals or rocks are found near the surface. The layer above the seam is removed and the exposed deposit is extracted using earth-moving machinery.

Quarry : Quarry is usually shallower than open pit mines. It is generally used for extracting building materials, such as limestone.

Underground Mine with Shafts : Underground mine is used when minerals occur deep below the surface or the minerals occur as veins in hard rock. Underground shaft mining is used to extract previous material. Shaft mines have vertical access to the seam via elevators, that carry workers and equipment into the mines, it is the deepest form of underground mining.


Question 4.
Superimpose the maps showing distribution of iron ore, manganese, coal and iron and steel industry. Do you see any correlation. Why ?

AP 10th Class Social Geography 5th Lesson Questions and Answers Minerals and Energy Resources Img 4
Correlation : Iron – ore, manganese, and coal are found very close to each other. Iron and steel industries have also been established in the same region. The reasons behind this are:
a) Iron-ore and manganese are the basic raw materials required for iron and steel industry.
b) Coal is also required in abundance, to produce energy for melting purposes.
c) Raw materials required for iron and steel industry are bulky.
d) Their transportation will be very costly. Therefore, industries have been established in the regions which are rich in iron, manganese and coal.
