3. Low rainfall variability

Select the correct answer:

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

View Answer
Answer: 1 and 2 only

1. Assam experienced one of the strongest earthquakes in 1950.
2. Earthquakes influence river morphology.
3. Earthquakes have negligible impact on floods.

Which are correct?

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

View Answer
Answer: 1 and 2 only
Explanation: The 1950 earthquake altered river courses and flood patterns. Hence statement 3 is incorrect.
Q. Consider the following about Assam’s rainfall extremes:

1. Cherrapunji influences rainfall in nearby Assam regions.
2. Assam experiences cloudburst-like events occasionally.
3. Rainfall variability is negligible.

Which statements are correct?

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

View Answer
Answer: 1 and 2 only
Explanation: Rainfall variability is high in Assam, contributing to floods and landslides.
Q. Which of the following contribute to soil erosion in Assam?

1. Shifting cultivation
2. Heavy monsoon rainfall
3. Dense forest cover

Choose the correct answer:

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

View Answer
Answer: 1 and 2 only
Explanation: Jhum cultivation and intense rainfall accelerate erosion. Dense forests reduce erosion.
Q. With reference to erosion in Assam, consider the following:

1. Bank erosion is severe along the Brahmaputra.
2. Both natural and anthropogenic factors contribute to erosion.
3. Erosion is absent in Upper Assam.

Which are correct?

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

View Answer
Answer: 1 and 2 only
Explanation: Erosion is widespread across Assam, including Upper Assam. Human activities worsen natural erosion.
Q. Which factors favor tea cultivation in Assam?

1. Acidic soil
2. High humidity
3. Frost-prone winters

Select the correct answer:

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

View Answer
Answer: 1 and 2 only

2. Basin-level planning is necessary.
3. Floods can be eliminated entirely.

Which are correct?

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

View Answer
Answer: 1 and 2 only

2. Varied topography and climate
3. Absence of human population

Which are correct?

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

View Answer
Answer: 1 and 2 only
Explanation: Human presence exists in Assam. Biodiversity is due to location and physiographic diversity.
Q. Which factors intensify flood hazards in Assam?

1. High sediment load of Brahmaputra
2. Tectonic instability of the region
3. Extensive deforestation in upper catchments

Select the correct answer:

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