7.The Horizontal angle made by the Survey Line with North Pole (Magnetic Meridian) or some reference direction , is called as
a. Bearing of line
b. Angle of line
c. Meridian of line
d. Fore Bearing of line
Answer Bearing of line
Meridian : Meridian is a direction with respect to which the direction of other
survey lines are mentioned. Types of meridian - 1. True meridian, 2. Magnetic
meridian 3. Arbitrary meridian 1. True meridian • It is the reference direction
of north pole of earth from a given station point. It is also called geographic
meridian. it is constant at a station. • The angle between the true meridian
and a survey line is known as 'true bearing' of the line. It is also known as
the 'Azimuth'. 2. Magnetic meridian • It is the reference direction of north
pole from magnetic needle. There may be variation in Magnetic bearing. The
angle between the magnetic meridian and a survey line is known as 'magnetic
bearing or simply 'bearing' of the line. 3. Arbitrary meridian: Sometimes for
survey of a small area a convenient direction is assumed as a meridian known as
'arbitrary meridian'. The angle between the arbitrary meridian and a survey
line is known as 'arbitrary bearing' of the line.
8. Bearing of a line is the horizontal angle it makes with
a. True meridian
b. Magnetic meridian
c. Arbitrary meridian
d. All of the above
answer is All of the above
9.The magnetic bearing of line measured clockwise from north pole towards the survey line, is called as
a. Whole Circle Bearing (W.C.B)
b. Reduced Bearing (R.B)
c. Meridian of line
d. Fore Bearing of line
Answer is Whole
Circle Bearing (W.C.B)
10.The bearing of line measured in the direction to the progress of survey is called as
a. Whole Circle Bearing (W.C.B)
b. Reduced Bearing (R.B)
c. Fore Bearing (F.B.)
d. Back Bearing (B.B.)
Answer is Fore Bearing (F.B.)

d. True North is 3 degree west of Magnetic North
answer is Magnetic North is 3 degree east of true North

d. It Indicates Quadrantal Bearing
answer is The Graduations are inverted
17. Which of the following statement is correct
a. Local Attraction affects included angle
b. The position of E and W are interchanged in Prismatic compass

d. None of the above. answer is None of the above.
18. The line joining points of Equal Dip are called as
a. Aclinic Lines
b. Isogonic Lines
c. Agonic Lines
d. Isoclinic Lines
answer is Isoclinic Lines
a. Aclinic Lines= The imaginary Line which is parallel to the Equator and passing through the points where Dip is Zero.
b. Isogonic Lines = These are the lines along which the declination has the same constant value.
