B. North direction and clockwise
Explanation
Bearing angle is measured from the North direction and clockwise. This means that when determining the bearing angle of a point or object, you start from the North direction and rotate in a clockwise direction to the desired point. This convention is commonly used in navigation and surveying to provide a consistent and standardized way of measuring angles.

Rate this question:

• 28.

### At which direction does a compass precisely point?

• A.

North Pole

• B.

Magnetic North

• C.

South Pole

• D.

True North

B. Magnetic North
Explanation
A compass precisely points towards Magnetic North. This is because the needle of a compass aligns itself with the Earth's magnetic field, which is generated by the movement of molten iron in the Earth's outer core. Magnetic North is not the same as True North, which is the direction towards the North Pole. The difference between Magnetic North and True North is known as magnetic declination and varies depending on the location on Earth. Therefore, in order to navigate accurately, it is important to account for this declination when using a compass.

### How can you distinguish between a Level and Theodolite?

• A.

By the levelling bubble

• B.

By the tripod

• C.

By instrument colour

• D.

Level’s scope does not tilt or rotate vertically.

D. Level’s scope does not tilt or rotate vertically.
Explanation
A level and a theodolite are both surveying instruments used for measuring angles and distances. However, one way to distinguish between them is by looking at the scope. A level's scope does not tilt or rotate vertically, while a theodolite's scope does have the ability to tilt and rotate vertically. Therefore, if the scope of the instrument is unable to tilt or rotate vertically, it can be identified as a level rather than a theodolite.
