On a contour map, a series of closed contours with values increasing towards the centre represents a:
सही उत्तर: घ) Hill
Closed contours with higher values inside indicate a hill; lower values inside indicate a depression.

The fore bearing of a line is S 40° E. Its back bearing is:
सही उत्तर: ग) N 40° W
In the quadrantal system, the back bearing has the same angle with opposite letters: N 40° W.

The horizontal distance between two consecutive contours on the ground is called the:
सही उत्तर: ख) Horizontal equivalent
Horizontal equivalent is the plan distance between successive contours; it varies with the steepness of the ground.

The reduced bearing of a line is N 35° W. Its whole circle bearing is:
सही उत्तर: घ) 325°
In the NW quadrant, WCB = 360° − 35° = 325°.

In levelling from a benchmark of RL 150.000 m, the sums of back sights and fore sights are 8.465 m and 10.215 m. The RL of the last point is:
सही उत्तर: क) 148.250 m
Last RL = First RL + ΣBS − ΣFS = 150.000 + 8.465 − 10.215 = 148.250 m.

Barometric levelling is based on the principle that atmospheric pressure:
सही उत्तर: ग) Decreases with increase in altitude
Since air pressure decreases with height, measuring pressure differences gives approximate elevation differences.

A levelling staff that is telescopic, with sections sliding into each other, is commonly known as:
सही उत्तर: ख) Sopwith staff
The Sopwith (telescopic) staff extends to about 4 m in sliding sections.

In the whole circle bearing (WCB) system, bearings are measured:
सही उत्तर: ग) Clockwise from north, from 0° to 360°
WCB is measured clockwise from the north end of the meridian, ranging from 0° to 360°.

In an automatic (auto) level, the line of sight is kept horizontal by:
सही उत्तर: ख) An internal compensator
An optical-mechanical compensator automatically maintains a horizontal line of sight once the instrument is roughly levelled.

-
The vertical angle that a freely suspended magnetic needle makes with the horizontal is called:
सही उत्तर: घ) Dip
Dip is the inclination of the magnetic needle to the horizontal, zero at the magnetic equator and 90° at the magnetic poles.
