India — LocationClass 11 India Physical Environment NCERT Solutions

Answer: (d) 6°45' N - 37°6' N

Explanation: The question asks for the latitudinal extent relevant for the entire area of India. While the mainland of India extends from 8°4' N in the south (Kanniyakumari) to 37°6' N in the north (Kashmir), the country's total area includes the island groups. As the source text mentions, 'Our southern boundary extends upto 6°45' N latitude in the Bay of Bengal,' which refers to the Indira Point in the Andaman and Nicobar Islands. Therefore, the complete latitudinal extent of the Indian Union is from 6°45' N to 37°6' N.

Answer: (a) Bangladesh

Explanation: Although the text does not provide the specific lengths of the borders, India shares its longest land frontier with Bangladesh. The border between India and Bangladesh is approximately 4,096 kilometers long and passes through the states of West Bengal, Assam, Meghalaya, Tripura, and Mizoram.

Answer: (a) China

Explanation: The source text states that India, with an area of 3.28 million sq. km, 'stands as the seventh largest country in the world.' The six countries larger than India in area are Russia, Canada, USA, China, Brazil, and Australia. Among the given options, only China is larger in area than India.

Answer: (b) 82°30' E

Explanation: The source text explicitly mentions the standard meridian for India. A footnote explains that there is a general understanding to select the standard meridian in multiples of 7°30' of longitude. It clarifies, 'That is why 82°30' E has been selected as the ‘standard meridian’ of India.' This longitude passes through the middle of the country and is used to determine the Indian Standard Time (IST).

Yes, there is a valid argument that India could have more than one standard time. The country has a vast longitudinal extent of about 30 degrees, which results in a time difference of nearly two hours between its easternmost and westernmost points. This large time gap means that the sun rises and sets much earlier in the northeastern states than in the western parts of the country. Having a single time zone can affect productivity and daily life in these regions. A separate time zone for the northeast could align working hours more closely with the natural cycle of day and night.

India's long coastline, which is 7,517 km including the island groups, has several significant implications:

India's vast latitudinal spread, from the tropical to the sub-tropical and warm temperate zones, is highly advantageous. As stated in the text, this location is 'responsible for large variations in land forms, climate, soil types and natural vegetation in the country.' This diversity allows for the cultivation of a wide variety of crops, supports rich biodiversity, and results in different lifestyles, cultures, and economic activities across the nation, contributing to its unique character and resource base.

Watches at Kohima and New Delhi show the same time because all of India follows a single, uniform time called the Indian Standard Time (IST). This time is based on the longitude of 82°30' E, which is designated as the 'standard meridian' of India. Although the local time based on sunrise and sunset differs across the country's vast east-west extent, adopting a standard meridian ensures that all clocks are synchronized. This system avoids confusion and is essential for coordinating railways, flights, and official communications nationwide.

To perform this activity, one would need to collect the data for the area and the number of districts for each state from an appendix or a reliable source. After plotting this data on a graph, it is likely that a general positive relationship would be observed. Typically, states with a larger geographical area tend to have a higher number of districts for better administrative management. However, this relationship is not perfectly linear, as historical, political, and population density factors also play a crucial role in the creation of districts.

Based on general geographical knowledge (as the data is in an appendix not provided), among the states listed:

There is generally a positive correlation between the area of a state and the number of its districts. Larger states often require more administrative units (districts) to govern effectively, manage resources, and provide services to the population spread over a vast territory. However, the relationship is not absolute. Other factors like population size and density, topography, and political considerations also influence the demarcation of districts. For instance, a small but densely populated state might have more districts than a large, sparsely populated one.

Based on the map of India, the states with coastal boundaries are:

An arrangement of states with only land boundaries, moving from west to east, could be as follows:

The Union Territories which have a coastal location are:

The variation in area and population between NCT Delhi and the Andaman and Nicobar Islands is due to their vastly different geographical and socio-economic characteristics.

This is an activity to be performed. To create the bar diagram, one would collect the area (in sq. km) and total population for each Union Territory of India from Appendix II or a reliable source. Using a graph paper, two separate bar diagrams could be drawn. One diagram would have the names of the Union Territories on the x-axis and their area on the y-axis. The second diagram would have the Union Territories on the x-axis and their population on the y-axis. These diagrams would visually represent the significant disparities in size and population among the UTs, such as the large area of Ladakh versus the small area of Lakshadweep, and the high population of Delhi versus the low population of Ladakh or Andaman and Nicobar Islands.
