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 — B, 'Maximum rainfall occurs between March and April'. The Andaman & Nicobar Islands sit in the path of BOTH monsoons and get most of their rain spread across roughly May to December (south-west monsoon May-September, north-east monsoon October/November-December); March-April fall in the drier pre-monsoon period. So the claim that maximum rainfall is in March-April is the statement that is NOT correct. The other three are accurate: the climate is a humid tropical/maritime one, the Ten Degree Channel (~150 km wide) separates the Andaman group from the Nicobar group, and the islands are home to Negrito tribes.
- (a)Climate is humid, tropical coastal climate — This is correct — the islands have a hot, humid tropical maritime climate — so it is NOT the false statement the question asks for.
- (c)Andaman and Nicobar islands are separated by 10 degree Channel which is 150 Km wide — This is correct — the Ten Degree Channel (about 150 km wide, running along 10 degree N) does separate the Andaman group from the Nicobar group — so it is not the answer.
- (d)Islands are inhabited by Negrito tribes — This is correct — the aboriginal Andaman tribes (Great Andamanese, Onge, Jarawa, Sentinelese) are of Negrito stock — so this statement is also true, not the exception.
The Andaman & Nicobar Islands are a Union Territory of about 572 islands in the Bay of Bengal, split into the Andaman group and the Nicobar group by the Ten Degree Channel. They have a hot, humid tropical maritime climate fed by both the south-west and north-east monsoons, so the rainy season is long (roughly May to December) rather than a single spring peak.
'Which statement is NOT correct' items reward spotting the single false detail among true ones. Here the rainfall timing is the plant: because A&N are wet for most of the year from two monsoons, the 'March-April maximum' claim stands out as wrong. The tribes, the Ten Degree Channel and the humid climate are all genuine facts.
- The Ten Degree Channel (~150 km wide, along 10 degree N) separates the Andaman group from the Nicobar group.
- Climate: hot, humid tropical maritime; heavy rainfall (~3000 mm) from both the south-west and north-east monsoons.
- Negrito tribes of the Andamans: Great Andamanese, Onge, Jarawa and Sentinelese.
- Highest point is Saddle Peak (North Andaman); Barren Island has India's only active volcano.
- Andaman tribes are Negrito, but the Nicobarese and Shompen of the Nicobars are of Mongoloid stock.
- A&N receive rain from both monsoons (long wet season), not a single spring peak.
