FAQs on CBSE Syllabus for Class 8 Social Science 2024-25 Exam
1. What is meant by a Population Pyramid?
The population pyramid is nothing but pictorially describing a population composition. For instance, if you consider an age-sex pyramid, it provides information related to people of different age groups as per their gender. This age-sex pyramid helps in determining a considerable amount of information about a nation. As you look at the bottom of the pyramid, you can get familiar with the rate of birth, whereas the top part indicates the death rate.
For our country India, the death rate is reducing and hence, the shape of the pyramid is broad for youth age people. Also, the pyramid size lessens at a steady pace.
2. How is Population Distribution Affected?
There are various factors that affect population distribution. For example, favourable climate, topography, soil fertility, and access to fresh water and minerals are significant factors that influence the density of an area's population. In general, individuals love to dwell on plain lands instead of mountains and plateaus and enjoy moderate weather conditions. Again, fertile lands are preferred compared to non-fertile ones, and places that hold mineral deposits are densely populated. Apart from these, some other social factors facilitating the population of a region are education and health facilities, housing, etc.
3. What is the Life History of Birsa Munda?
Birsa, belonging to the family of Mundas, was born in the mid-1870s. The place was Chottanagpur. He spent his childhood in the Bohanda forests, playing flute and grazing sheep. He also used to take part in dancing in the local akharas.
As he grew up, Birsa listened to stories associated with the Munda uprisings and saw leaders talking and requesting people for protest. The missionaries also inspired Mundas to revolt against their rights, and Birsa was interested in their speeches. Besides, Birsa also loved the company of a Vaishnav preacher and wore the sacred thread as well. This showed how much importance he placed on piety and purity.
4. What are the major sources of pollution in India and how is the Indian Government combating that?
The major sources of pollution in our country are as follows
· Harmful gasses emitted by old vehicles and industries

· Plastics and polythene degrade the soil.
However the Indian government is taking every necessary step to combat the pollution. The following step have been taken to reduce the pollution
· Old public and private vehicles have been banned so that no more harmful gasses are emitted from vehicles. Factories emitting harmful gasses are closed down.
· Industrial wastes are properly processed before disposing of them. Disposing of wastes of any sort in the river is totally banned.
Many more steps like the use of CNG vehicles in all places, banning plastic bags, use of public transport instead of private transport have to be taken for further reduction of pollution.
5. How is the Government formed in India?
India is a democratic country. Here Government is by the people, for the people and of the people. The Indian Government is formed by elections. The winners of the election are the members of parliament or MPs. The party that secures a majority of MPs winning the majority of Lok sabha seats becomes the ruling party. In our system a party needs to secure at least 272 such seats in Parliament to form the Government either singly or with the coalition with other parties. Usually a coalition Government is formed by two or more parties having the same view and goal. The other majority party forms the opposition party who checks and criticizes any wrong action of the ruling party.
