Read the extract and answer the questions that follows :
The latitudinal and longitudinal extent of the mainland is about 30°. Despite this fact, the east-west extent
appears to be smaller than the north-south extent. From Gujarat to Arunachal Pradesh, there is a time lag of
two hours. Hence, time along the Standard Meridian of India (82°30’E) passing through Mirzapur (in Uttar
Pradesh) is taken as the standard time for the whole country. The latitudinal extent influences the duration of
day and night, as one move from south to north. The Indian landmass has a central location between the East
and the West Asia. India is a southward extension of the Asian continent. The Trans Indian Ocean routes,
which connect the countries of Europe in the West and the countries of East Asia, provide a strategic central
location to India.
(i) Name the northern-most and southern most latitude of India.
(ii) Why is there a standard meridian needed for India?
(iii) What is the benefit of having a central location in Asia for India? pls fast it's urgent
Answers
Answer:
Longitudinal and Latitudinal extent
The latitudinal extent of India from the north end Kashmir to south end Kanniyakumari is 37°6′N to 8°4′N
The longitudinal extent of India from west end Gujarat to east end Arunachal Pradesh is 68°7′E to 97°25′E.
On calculating both of these extents we get to that these are approximately of 30°.
Distance between the two ends
The actual distance between the ends North and South is 3214 km.
The distance between two ends east and west is 2933 km.
Why North-South extent longer than the East-West extent?
North-South extent longer than the East-West extent due to the following reasons:
The distance between latitudes remain the same throughout but the distance between the two longitudes reduces as moved towards poles
The distance between two latitudes is constant that is 111 km but the distance between two longitudes is 111 km at the equator and reduces to 0 at the poles.
In other words, we can say that India’s north-south extent and distance remains unaltered
The distance between the two longitudes decreases and the east-west extends has a U shaped bending which actually reduces the actual east-west distance.
Hence, the lines of longitude come nearer and the East-West distance becomes less than the North-South distance.
Answer:
Name the northern-most and southern most latitude of India.
