1.What is a geoid?
A. Points spread on the land, materialized by sustainable signal, visible from long distance or
«can be a station» coordinates had been calculated with precision, take into account the
earth form.
B. Surface that separates solid part of earth (terrestrial crust) and the liquid part (sea) or gas
(air or atmosphere)
C. Equipotential surface of gravity forces, situated at sea and ocean level, normal for each
point to «vertical line (plumb line or line of gravity) », irregular form, depend on the
repartition of constitutive masses of earth.
D. A regular geometric form, obtain by rotation of ellipse around one of two axes and used
conventionally to represent approximately the earth’s form.
2. What the difference between true north and magnetic north?
A. Nothing different.
B. True north is the direction of the meridian point towards the North Pole. Magnetic North is the
direction of the blue tip of the compass needle.
C. True north is the direction of the pole star. Magnetic North is the direction of the blue tip of the
compass needle.
D. True north is the direction of the blue tip of the compass needle. Magnetic North is the direction of
the meridian point towards the North Pole.
