A benchmark established at the end of a day's work so that levelling can be continued from it the next day is a:
सही उत्तर: ग) Temporary benchmark
Temporary benchmarks are set on firm objects at stopping points to carry the work forward.

Highly precise benchmarks established at intervals throughout a country by the national survey organisation are called:
सही उत्तर: घ) Great Trigonometrical Survey (GTS) benchmarks
GTS benchmarks are established with very high precision by the national survey authority and serve as reference for other levelling.

A level surface in surveying is a surface that is:
सही उत्तर: ख) Everywhere perpendicular to the direction of gravity (the plumb line), like the surface of still water
A level surface is curved, following the mean spheroidal shape of the earth, and is normal to the plumb line at every point.

In plane table surveying, the trough compass is used to:
सही उत्तर: ग) Orient the plane table along the magnetic meridian
The trough compass provides an approximate orientation of the table with respect to magnetic north.

-
The true bearing of a line is 75° and the magnetic declination at the place is 5° East. The magnetic bearing of the line is:
सही उत्तर: घ) 70°
True bearing = magnetic bearing + east declination, so magnetic bearing = 75° − 5° = 70°.

-
The whole circle bearing of a line is 135°. Its quadrantal (reduced) bearing is:
सही उत्तर: ख) S 45° E
A WCB between 90° and 180° lies in the SE quadrant; reduced bearing = 180° − 135° = S 45° E.

-
A surveyor's compass reads bearings in the:
सही उत्तर: घ) Quadrantal (reduced) bearing system
The surveyor's compass gives quadrantal bearings (N/S, angle, E/W), whereas the prismatic compass gives whole circle bearings.

-
The magnetic needle has zero dip (rests horizontal) at the:
सही उत्तर: ख) Magnetic equator
Dip is zero at the magnetic equator and increases to 90° at the magnetic poles.

-
The variation in magnetic declination that occurs during the course of a day is called:
सही उत्तर: ग) Diurnal variation
Diurnal (daily) variation is a small regular change in declination over 24 hours.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The slow, long-period change in magnetic declination extending over centuries is called:
सही उत्तर: घ) Secular variation
Secular variation is the large, slow swing of declination over long periods, the most important variation for old survey records.
