Question

A line joining places of equal declination is called
A. aclinical
B. isoclinical
C. isodynamical
D. isogonal

Answer 1

Hint: A-line is the joining of different points; it is straight and can draw in any angular positions with respect to any body. The declination is the angle that can be measured or named between two lines. We can even find this term declination in the celestial equator angle, which means the angle between two points of the celestial equator, whether it is on the north side or south side.

Complete step by step answer:
Declination is the angle between any two bodies or lines, so here it is given that equal declination which means the angles are equal and the lines are the reason for equal declination. If we observe the options, the term isogonal will be the right one because the term “iso” means similar or equal and “gonal” will be the term used for angles, totally a body or line that has similar angles are called as the isogonal which suits the question that given.
Therefore, a line joining places of equal declination is called as the isogonal, it means the option (D) is correct.

Note:We have to be aware of the prefix words, which means words like un, iso, a, used before any word that can change the entire meaning. The prefix “iso” means the same or equal and also, the prefix term “a” will mean the same as “iso.” For example, the word thermal which means the heat, but when we add the prefix iso to it, become isothermal, which means the two bodies are in equal thermal stages.
