D performs her train journey by the shortest route from Bengaluru to New Delhi. Which one of the following rivers will she not cross while performing the journey?

  1. A.Narmada
  2. B.Yamuna
  3. C.Godavari
  4. D.Krishna

Correct answer

B. Yamuna

Explanation

The correct answer is B, Yamuna. The shortest rail route from Bengaluru reaches Delhi from the south through Agra and Mathura, which lie on the western side of the Yamuna, so the train never has to cross that river.

The route runs north from Bengaluru across the Deccan to Hyderabad, then through Nagpur, Itarsi, Bhopal, Jhansi and Agra to New Delhi. On the way it crosses the great peninsular rivers that flow east towards the Bay of Bengal: the Krishna in the south of the plateau and the Godavari further north. Near Itarsi it crosses the Narmada, which flows west through its rift valley. Agra, Mathura and New Delhi all stand on the right, or western, bank of the Yamuna, so the line runs alongside the river instead of crossing it.

A is wrong because the line crosses the Narmada in Madhya Pradesh, near Itarsi. C is wrong because the train crosses the Godavari in Telangana. D is wrong because the Krishna is crossed in the south, on the stretch towards Hyderabad.

Exam tip: Agra, Mathura and Delhi are on the western bank of the Yamuna; a train from the south crosses the Krishna, Godavari and Narmada but not the Yamuna.

Consider the following statements with reference to earthquakes:

1. Collapse earthquakes are most common.

2. Tsunamis are waves generated by the tremors and not an earthquake in itself.

3. High magnitude earthquakes i.e. 8+ are quite rare whereas 'tiny' types occur almost every minute.

Which of the statements given above are correct?

  1. A.1 and 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

Statement 1 is false because tectonic earthquakes, not collapse earthquakes, are the most common type. Earthquakes are grouped by cause: tectonic (sliding of rocks along a fault), volcanic, collapse (the roofs of underground mines or caverns falling in), explosion (from nuclear or chemical blasts) and reservoir-induced.

Q3.GeographyAsked in: CDS · CDS-II 2016, GKMedium

With reference to earthquakes, which of the following statements are correct?

1. Earthquakes largely occur along the converging plate boundaries.

2. Point of origin of earthquake in lithosphere is known as focus/hypocentre.

3. Intensity of earthquake decreases with distance from the epicentre.

4. Epicentre of earthquake always remains over continents only.

Select the correct answer using the code given below.

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

The first three statements are true, while statement 4 is false because many earthquakes have their epicentre under the sea.

Select the answer using the code given below:

  1. A.1 and 2 only
  2. B.1 and 3 only

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

All three statements describe, in the right order, the three stages through which the present atmosphere of the Earth evolved.
