Question 1

Consider the following statements in regard to Beaufort scale for wind speeds, (i) The Beaufort number ranges from 1 to 12. (ii) Higher Beaufort number indicates higher speed of wind, (iii) Beaufort number for calm is smallest and for hurricane ishighest Of these statements
A)(i) and (ii) are correct
B)(ii) and (iii) are correct
C)(i) and (iii) are correct
D)(i), (ii) and (iii) are correct

Accepted Answer

The Beaufort scale ranges from 0 to 12, not 1 to 12. Higher numbers do indicate higher wind speeds, and the scale starts with 0 for calm and goes up to 12 for hurricane-force winds.

Question 2

The shore line survey includes:
A)Depicting the shore line
B)Depicting the prominent details on shore line
C)Depicting the high water line
D)All the above

Accepted Answer

A shoreline survey includes depicting the shoreline itself, the prominent details along the shoreline, and the high water line, making all the options correct.

Question 3

A harbour is a place where
A)Ships get shelter and protection against destructive forces due to sea waves
B)Facilities are provided for receiving cargo and passengers
C)Port buildings are constructed for commercial purposes
D)All of the above

Accepted Answer

A harbour is a place that provides shelter and protection for ships, facilities for cargo and passengers, and may include port buildings for commercial activities.

Question 4

Assertion A: Large size stones are required in stone revetment in shore protection. Reason R: Resistance of stone to wave force is proportional to its volume and wave force is proportional to the exposed area of the stone. Select your answer based on the coding system given below.
A)Both A and R is true and R is the correct explanation of A
B)Both A and R is true but R is not a correct explanation of A
C)A is true but R is false
D)A is false but R is true

Accepted Answer

The assertion and reason are both true, and the reason correctly explains the assertion. Larger stones are preferred in shore protection because their larger volume provides greater resistance to wave forces, which indeed are proportional to the stone's exposed surface area.

Question 5

A roadstead:
A)Is a protected area of water where boats can move safely
B)Is the end of the road at the harbour
C)May be protected by break water walls
D)None of these

Accepted Answer

A roadstead is a protected area of water where boats can anchor safely, typically without the need for breakwater walls.
