After NEP 2023, Assertion Reason is an important part of the question paper that is why students should try to practice it before examination. Below, you can find Chapter 1 Assertion Reason of Class 6 Social Science Textbook.
Directions: Read the Assertion (A) and Reason (R) carefully and choose the correct option.
Options:
- (A) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
- (B) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
- (C) Assertion is true but Reason is false.
- (D) Assertion is false but Reason is true.
1. Assertion (A): A globe generally represents the Earth more accurately than a flat map.
Reason (R): The Earth and the globe have nearly the same spherical shape.
Answer: (A)
Explanation: The Earth is nearly spherical and a globe reproduces this shape more accurately than a flat map. Therefore, the globe shows continents, oceans and relative positions with less distortion. The Reason correctly explains the Assertion.
2. Assertion (A): Every country in the world follows only one standard time.
Reason (R): Large countries may extend across several longitudes.
Answer: (D)
Explanation: The Assertion is false because some large countries such as Russia, Canada and the USA, have multiple standard times. The Reason is true because these countries cover a vast east-west extent and therefore use several time zones.
3. Assertion (A): The Equator is the largest parallel of latitude.
Reason (R): All parallels of latitude are equal in length.
Answer: (C)
Explanation: The Equator is indeed the largest parallel. However, all parallels are not equal in length. They become progressively smaller towards the poles. Therefore, the Assertion is true but the Reason is false.
4. Assertion (A): Longitude helps in determining the local time of a place.
Reason (R): Different longitudes receive sunlight at different times due to the Earth’s rotation.
Answer: (A)
Explanation: As the Earth rotates from west to east, places situated on different longitudes experience sunrise, noon and sunset at different times. Therefore, longitude is directly related to local time. The Reason correctly explains the Assertion.
5. Assertion (A): Latitude is measured eastward and westward from the Prime Meridian.
Reason (R): Longitude is measured eastward and westward from the Prime Meridian.
Answer: (D)
Explanation: Latitude is measured northward and southward from the Equator, so the Assertion is false. Longitude however is measured eastward and westward from the Prime Meridian. Therefore, the Reason is true.
6. Assertion (A): Symbols make maps easier to understand.
Reason (R): Symbols are standard signs used to represent various features on maps.
Answer: (A)
Explanation: Symbols allow map makers to show many features within limited space. Since standard symbols are commonly understood, maps become easier to read and interpret. The Reason correctly explains the Assertion.
7. Assertion (A): The Prime Meridian passes through Greenwich in England.
Reason (R): Greenwich was chosen as the international reference meridian in 1884.
Answer: (A)
Explanation: In 1884, many nations agreed to adopt the Greenwich Meridian as the international Prime Meridian. Therefore, the Prime Meridian passes through Greenwich. The Reason correctly explains the Assertion.
8. Assertion (A): The Equator divides the Earth into the Eastern and Western Hemispheres.
Reason (R): The Prime Meridian divides the Earth into the Eastern and Western Hemispheres.
Answer: (D)
Explanation: The Equator divides the Earth into the Northern and Southern Hemispheres, making the Assertion false. The Prime Meridian divides the Earth into the Eastern and Western Hemispheres, so the Reason is true.
9. Assertion (A): Latitude and longitude together form a system of coordinates.
Reason (R): A place can be located precisely using only its latitude.
Answer: (C)
Explanation: Latitude and longitude together form coordinates that help identify the exact location of a place. Latitude alone is insufficient because many places can lie on the same latitude. Thus, the Assertion is true but the Reason is false.
10. Assertion (A): The International Date Line is exactly the same as the 180° longitude throughout its course.
Reason (R): The International Date Line deviates in some places to avoid dividing countries into two different dates.
Answer: (D)
Explanation: The Assertion is false because the International Date Line is only approximately along 180° longitude and bends in several places. The Reason is true and correctly describes why these deviations occur.
11. Assertion (A): India extends approximately from 8°N to 37°N latitude.
Reason (R): India lies entirely in the Southern Hemisphere.
Answer: (C)
Explanation: India does extend approximately from 8°N to 37°N latitude. However, all these latitudes are north of the Equator, which means India lies in the Northern Hemisphere, not the Southern Hemisphere. Therefore, the Assertion is true but the Reason is false.
12. Assertion (A): A map of a village and a map of the whole world can use the same scale.
Reason (R): Different maps use different scales depending on the area being represented.
Answer: (D)
Explanation: Maps representing small areas usually use a large scale while maps showing large areas use a small scale. Therefore, the Assertion is false. The Reason correctly states that scales vary according to the area shown.
13. Assertion (A): The circles formed by parallels of latitude become smaller towards the poles.
Reason (R): The Equator is the largest parallel of latitude.
Answer: (B)
Explanation: Both statements are true. The Equator is indeed the largest parallel and other parallels become smaller towards the poles. However, the Reason does not directly explain why the circles become smaller; it is simply a related fact. Therefore, option B is correct.
14. Assertion (A): Coordinates help us determine the precise location of a place on Earth.
Reason (R): Coordinates are formed by the intersection of parallels of latitude and meridians of longitude.
Answer: (A)
Explanation: A location is identified by its latitude and longitude. The intersection of a particular latitude and longitude gives the exact position of a place. Thus, the Reason correctly explains the Assertion.
15. Assertion (A): The Survey of India has fixed a set of symbols for maps of India.
Reason (R): Different countries may use different sets of map symbols.
Answer: (B)
Explanation: Both statements are true. The different countries may use different symbols and that the Survey of India has fixed symbols for maps in India. However, the second statement does not directly explain the first. Hence, option B is correct.
16. Assertion (A): If it is noon at Greenwich, it will be 1 pm at 15°E longitude.
Reason (R): The Earth rotates 15° every hour.
Answer: (A)
Explanation: Since the Earth rotates 360° in 24 hours, it rotates 15° in one hour. Therefore, a place located 15° east of Greenwich experiences local time one hour ahead. The Reason correctly explains the Assertion.
