Which statement is NOT correct with reference to Andaman and Nicobar Islands?
- A.Climate is humid, tropical coastal climate
- B.Maximum rainfall occurs between March and April
- C.Andaman and Nicobar islands are separated by 10 degree Channel which is 150 Km wide
- D.Islands are inhabited by Negrito tribes
Correct answer
Explanation
The correct answer is B, Maximum rainfall occurs between March and April. The islands get most of their rain from the south-west monsoon, from about May to September, with more from the north-east monsoon later; March and April are among the driest months.
The Andaman and Nicobar Islands lie in the Bay of Bengal close to the equator, so they are hot and humid all year, with annual rainfall of roughly 3000 mm. The monsoon reaches them first, usually in the third week of May, before it touches Kerala. The Ten Degree Channel, along the 10°N parallel, separates Little Andaman from Car Nicobar and is about 150 km wide. The Andamans are home to Negrito tribes such as the Great Andamanese, Onge, Jarawa and Sentinelese.
A is correct: the islands have a humid, tropical maritime climate with little difference between seasons.
C is correct: the Ten Degree Channel divides the Andaman group from the Nicobar group and is about 150 km wide.
D is correct: the Negrito Jarawa, Onge and Sentinelese live in the Andamans, while the Nicobarese and Shompen of the Nicobars are of Mongoloid stock.
Exam tip: Ten Degree Channel separates Andaman and Nicobar; Duncan Passage separates South and Little Andaman.

Read the full explanation →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?
- A.1 and 2 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
Show answer
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.

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.
- A.1 and 2 only
- B.1, 2 and 3
- C.2 and 3 only
