Assertion Reason Geography Chapter 5 Minerals and Energy Resources Contemporary India II
Questions of Assertion Reason of Geography Chapter 5 Minerals and Energy Resources Social Science CBSE Class 10 are very simple to understand as this chapter deals with Minerals and Energy Resources. To solve assertion reason type questions of Geography of Social science, deeper understanding of concept about Minerals and Energy Resources is required. In order to help the student in solving Assertion Reason type of questions, detailed process is explained.
How to solve Assertion Reason Type Questions?
In Assertion-Reason type of question, two statements are given, first is Assertion and second is called Reason. Student must have to think critically about both the statements in Assertion Reason Questions, since it combines multiple choice questions and true/false type of questions which requires a higher level of understanding.
How many types are there of Assertion Reason Type Questions?
Assertion-Reason type of questions can be asked either with four MCQ options or with five MCQ options. First four options are same in both the cases only one more options is being provided i.e. last one. One extra option increases the difficulty level of the questions.
In assertion reason type of questions, all 4 or 5 options are same for each question, which are as:
(a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true but reason (R) is false.
(d) Assertion (A) is false but reason (R) is true.

| If True | False | (c) Assertion (A) is true but reason (R) is false. |
| If False | True | (d) Assertion (A) is false but reason (R) is true. |
| If False | False | (e) Both Assertion and Reason are false. |
Now, lets practice some Assertion Reason Questions of Contemporary India II : Geography – Chapter 5: Minerals and Energy Resources.
Read instructions carefully before answering the questions.
For question given below, two statements are given- one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below:
(a) Both A and R are true and R is correct explanation of the assertion.
(b) Both A and R are true but R is not the correct explanation of the assertion.
(c) A is true but R is false.
(d) A is false but R is true.

Assertion (A) : Uses of iron brought a radical change in human life.
Reason (R) : Different kinds of tools where invented by using minerals.
Ans.1. (a)
Both assertion and reason are true and reason is the correct explanation of assertion. Revolution in agriculture-different type of tools invented like axe, hook, plough etc., revolution in industry-different tools and machines like spinning and also revolution in transportation- bullock- cart, ships, boats etc. brought a radical change in human life.
Question.2.
Assertion (A) : Mining activity is often called a “Killer Industry”.

Assertion (A) : Iron ore is the basic mineral and the backbone of India.
Reason (R) : India is rich in good quality Iron ore.
Ans.3. (a)
Both assertion and reason are true and reason is the correct explanation of assertion. Iron ore is the basic mineral and the backbone of industrial development. India is rich in good quality iron ores. Iron ore is exported largely from India, however the reason does not justify the assertion.
Question.4.
Assertion (A) : Mica is a metallic mineral.
Reason (R) : Mica mineral is the basic raw material for cement industry.
Ans.4. (d)
Both assertion and reason are false. Mica is a mineral made up of a series of plates or leaves. It is a non-metallic mineral and it is used in electric and electronic industries.
Question.5.
Assertion (A) : Minerals are an indispensable part of our lives.
Reason (R) : Minerals have a universal use, they are used to manufacture everything we use in our day to day lives.
Ans.5. (a)
Both assertion and reason are true and reason is the correct explanation of assertion. Minerals are found in varied forms in nature. Even the food that we eat contains minerals. Almost everything we use, from a tiny pinto a towering building or a big ship, all are made from minerals.
Question.6.
Assertion (A) : Geological processes of mineral formation is slow
Reason (R) : Minerals resources are consumed way quickly than they are formed.
Ans.6. (b)
Both assertion and reason are true but reason is not the correct explanation of assertion. Mineral formation is slow as it requires millions of years to be created but are used very quickly in comparison.
Question.7.
Assertion (A) : Thermal power stations are located on or near the coalfields.
Reason (R) : Coal is a bulky material, which loses weight on use as it is reduced to ash. Hence, heavy industries and thermal power stations are located on or near the coalfields.
Ans.7. (a)
Both assertion and reason are true and reason is the correct explanation of assertion. The reason justifies the assertion.
Question.8.
Assertion (A) : Natural gas is referred as an environment friendly fuel.
Reason (R) : Natural gas contains low carbon dioxide emissions.

Reason (R) : Fossil fuels such as coal, oil and gas are easily obtained from natural resource.
Ans.9. (d)
Both assertion and reason are false. Increased use of fossil fuels causes serious environmental problems. Hence, there is a pressing need to use renewable energy sources like solar energy, wind, tide, biomass and energy from waste material.
Question.10.
Assertion (A) : Conservation of Energy Resources is essential.
Reason (R) : Energy is a basic requirement for economic development.
Ans.10. (a)
Both assertion and reason are true and reason is the correct explanation of assertion. Energy saved is energy produced, the economic development plans implemented since Independence necessarily required increasing amounts of energy to remain operational.
