CBSE NCERT Solved Question Answer

Q1. What do you understand by secondary activities?
A1. In the Secondary activities or manufacturing there is change of raw materials into products of more value to people. For example- pulp changes into paper and paper into a note book. These represent the two stages of the manufacturing process.
The paper made from pulp and cloth made from cotton had value added to them at each stage of the manufacturing process. In this way the finished product has more value and utility than the raw material that it is made from.

Q2. What do you mean by the term industry?
A2. Industry refers to an economic activity that isconcerned with production of goods, extraction of minerals or the provision of services. Thus we have ironand steel industry (production of goods), coal miningindustry (extraction of coal) and tourism industry (service provider).

Q3. Classify industries on the basis of the following heading with the help of examples:-
1) Raw material.        2) Size.        3) Ownership.
A3.On the basis of raw materials industries can be divided into the following types:-
a). Agro based industries use plant and animal based products as their raw materials. Food processing, vegetable oil, cotton textile are examples of agro- based industries.
b)    Mineral based industriesare primary industries that use mineral ores as their raw materials. Iron from iron ore is used as raw material for the manufacture of a number of other products, such as heavy machinery, building materials and railway coaches.
c)     Marine based industriesuse products from the sea and oceans as raw materials. Industries processing sea food or manufacturing fish oil are some examples.
d) Forest based industriesutilise forest produce as raw materials.The industries associated with forests are pulp and paper, pharmaceuticals, furniture and buildings.

On the basis of the size, industries can be classified into the following types:-
a) smallscale. Cottage or household industries are a type of small scale industry where the products are manufactured by hand, by the artisans.eg- Basket weaving and pottery. It uses lesser amount of capital and technology.

b) large scale industries. It use more amount of capital and technology. It produce large volumes of products. Eg- Production of automobiles and heavy machinery are large scale industries.
