The Standard Meridian of India is:

  1. A.82° 30′ E longitude
  2. B.83° 30′ E longitude
  3. C.82° E longitude
  4. D.82° 50′ E longitude

Correct answer

A. 82° 30′ E longitude

Explanation

The correct answer is A, 82° 30′ E longitude. India keeps one standard time for the whole country, Indian Standard Time, based on the 82° 30′ E meridian, which passes near Mirzapur in Uttar Pradesh. Since the Earth turns one degree every 4 minutes, 82.5 degrees gives 330 minutes, so IST is 5 hours 30 minutes ahead of Greenwich Mean Time. The meridian was chosen because it runs roughly through the middle of India’s east-west spread of about 30 degrees of longitude, from about 68° 7′ E in Gujarat to 97° 25′ E in Arunachal Pradesh. That spread makes the sun rise nearly two hours earlier in Arunachal than in Gujarat. The line passes through five states: Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Odisha and Andhra Pradesh. Option B is wrong because 83° 30′ E is one degree too far east. Option C is wrong because 82° E is half a degree short of the standard meridian. Option D is wrong because 82° 50′ E is not the chosen line either. Exam tip: 82° 30′ E × 4 minutes = 5 hours 30 minutes ahead of GMT.

Which of the following statements is/are correct? 1. Himalayan rivers have their origin in the snow-covered areas, hence are dry in winter season. 2. Rivers of the Peninsular Plateau have reached maturity. 3. Himalayan rivers depict all the three stages of normal cycle of erosion. Select the correct answer using the code given below.

  1. A.2 only
  2. B.1 and 3 only
  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

Which of the following statements related to latitude are true? 1. Rainfall, temperature and vegetation vary with latitude. 2. The difference between the longest day and the shortest day increases with latitude. 3. Indira Point is located approximately at 6°45' N latitude. Select the correct answer using the code given below.

  1. A.1 and 2 only

  3. C.2 and 3 only
  4. D.1, 2 and 3
Show answer
Correct answer: D. 1, 2 and 3

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
