Assertion Reason Geography Chapter 1 Resources and Development Contemporary India II
Questions of Assertion Reason of Geography Chapter 1 Resources and Development Social Science CBSE Class 10 are very simple to understand as this chapter deals with Resources and Development . To solve assertion reason type questions of Geography of Social science, deeper understanding of concept about Resources and Development 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.
(e) Both Assertion and Reason are false.
Then a question haunts in every student’s mind, which option is correct and when?
This can be understood clearly with the following table:
| Assertion (A) | Reason (R) | MCQ Options (Fixed for all questions) |
|---|---|---|
| If True | True | (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A). |
| If True | True | (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A). |
| 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 1: Chapter 1 Resources and Development.
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.
Question.1.
Assertion (A) : Alluvial soil is ideal for growth of paddy, wheat, cereal and pulse crops.
Reason (R) : Alluvial soil is well-known for is capacity to hold moisture.
(c) A is true but R is false.
Explanation: Alluvial soil contains adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal andpulse crops. Not water-retention but this property makes it ideal for the growth of wheat, paddy, cereal and pulse crops.
Question.2.
Assertion (A) : The availability of resources is not the only necessary condition for the development of any region.
Reason (R) : Not only availability of resources but also corresponding change in technology is necessary for development of any region.
(a) Both A and R are true and R is correct explanation of the assertion.
Explanation: Mere availability of resources in the absence of corresponding changes in technology and institutions may hinder development. Thus, both resources and advanced technologies contribute in development of a region.
Question.3.
Assertion (A) : Resources are free gifts of nature.
Reason (R) : Resources like soil, air, water are easily available in nature.
(d) A is false but R is true.
Explanation: Resources are not free gifts of nature but are present tjue to interaction of human beings with nature, technology and institutions. They are a function of human activities. They transform material available in our environment into resources.
Question.4.
Assertion (A) : Land is a natural resource of utmost importance.
Reason (R) : Land can be used for various purposes.
(a) Both A and R are true and R is correct explanation of the assertion.
Explanation: Land is a natural resource of utmost importance as it supports human life and wild life, economic activities like agriculture, mining, transport and communication system.
Question.5.
Assertion (A) : Resource planning is an easy process in India.
Reason (R) : Resource planning involves planning structure, identification and inventory of resource across the regions.
(d) A is false but R is true.
Explanation: Resource planning is a not an easy but a very complex process as it involves surveying, mapping, quantitative and qualitative estimation and measurement of the resources.
Question.6.
Assertion (A) : Soil is the most important renewable natural resource.
Reason (R) : Soil supports different types of living organisms on earth.
(a) Both A and R are true and R is correct explanation of the assertion.
Explanation: Soil is a living system. Soil helps to grow plants, supports natural vegetation and economic activities like agriculture Its universal usage proves that it is the most important renewable natural resource.
Question.7.
Assertion (A) : Processes of soil formation and erosion goes simultaneously and creates a balance between the two.
Reason (R) : The denudation of the soil cover and subsequent washing down is soil erosion
(c) A is true but R is false.
Explanation: Soil formation and erosion goes simultaneously but this balance is disturbed due to human activities like deforestation, over-grazing, construction, mining and natural forces like wind, glacier and water lead to soil erosion.
Question.8.
Assertion (A) : Arid soil is unsuitable for cultivation.
Reason (R) : Arid soil is generally sandy in texture and saline in nature. It restricts
the filtration of water.
(c) A is true but R is false.
Explanation: Due to dry climate and high temperature, evaporation is faster and the soil lacks humus and moisture that is why it becomes unfit for cultivation.
Question.9.
Assertion (A) : Controlling on mining activities doesn’t control land degradation.
Reason (R) : In states like Gujarat, Rajasthan, Madhya Pradesh, deforestation has occurred due to overgrozing, not minings.
(d) A is false but R is true.
Explanation: Activities of mining controls land degradation because mining sites are abandoned offer excavation work, this results in over – burdening. Mining activities in the mentioned states has contribution to deforestation.
Question.10.
Assertion (A) : Terrace cultivation does not restrict erosion.
Reason (R) : Running water cuts through the clayey soils and makes deep channels as gullies. This helps to cultivate crops.
(d) A is false but R is true.
Explanation: Terraces, out on slopes in forms of steps breaks up the force of the wind, thus preventing erosion. Gullies render cultivation in those lands impossible.
Question.11.
Assertion (A): Resources are free gifts of nature.
Reason (R): Resource are a function of human activities.
(a) Both A and R are true and R is correct explanation of the assertion.
