Line joining the points of equal variation is known as Iogonic line andthe line joining the points of zero variation is know as Agonic line.
it is different in different points of the year.
They are used to locate a certain place on a map.
The geographical North and South Pole - not the magnetic poles.
It is a line connecting all points at which there exists an equal vertical distance between the earth's surface and the water table.
Global Positioning System
We have several reference points on the Earth's surface, for our convenience. The North and South Poles are a couple. The choice of Greenwich as the zero longitude, and of the International Date Line are another two. These points have no specific feature on the surface, they are decided on for the convenience of the users.
The answer is very simple it's an isotherm map because an isobar map are lines that connect areas of the same pressure therefore lines that connect areas of the same temperature is and isotherm map
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
