What is the longitude of a town Y whose local time is 12:00 noon when Greenwich mean time is 6:00pm
90\(^o\) W
180\(^o\) E
150\(^o\) W
80\(^{o}\) E
Correct answer is A
Town Y? W|12:00noon ←(substract) Longitude(0^o)|E 6:00pm
Time difference = 6:00pm - 12:00pm = 6hours
Recall: 15o ≡ 1 hour therefore 6hours ≡ (15 x 60)o= 90o
Arrow is pointing to the west;hence, the latitude of Town Y is 90oW
One of the following is not a sequence of denudation
Erosion
Transportation
Decomposition
Deposition
Correct answer is C
The four sequences or stages of denudation are weathering, erosion, transportation and deposition
Which of the following is not a precaution to be taken when making a compass traverse?
The bearing should not be observed from a position close to strongly magnetic materials
The 'back' bearing should be taken from the other end of the line and should differ from the 'on'/'forward' bearing by exactly 180\(^{o}\)
All magnetic materials should be removed from the body and pockets of the reader before the bearing is taken
The compass must be held vertically so that the edge of the card does not rub against the top of the compass
Correct answer is D

Arrange the following scales in ascending order: 1:50,000, 1:200,000, 1:200, 1:300,000
1:200,1:50,000,1:200,000, 1:300,000
1:300,000,1:200,000,1:50,000,1:200
1:50,000, 1:200,000,1:300,000, 1:200
1:300,000, 1:200, 1:50,000, 1:200,000
Correct answer is B
The larger the denominator of a scale, the smaller the scale and the smaller the denominator of a scale, the larger the scale. Hence, the ascending order is 1:300,000< 1:200,000< 1:50,000< 1:200
