It may not be important, but it IS a matter of wide interest, because it determines

the length of daylight and darkness everywhere on Earth, as well as the onset of

each change of seasons.

Why is magnetic Declination is important?

Because if you need to use your compass to figure out which direction is north,then you need to know by how much the direction the compass points is wrong,and which way. That's the magnetic declination.


Why is it important to know magnetic declination when using a compass?

Knowing the magnetic declination is important when using a compass because it helps you correct for the difference between magnetic north (the direction the needle points) and true north (the direction of the North Pole). Failing to account for this difference can lead to navigational errors when trying to follow a specific heading on a map.


When using a compass to map an area why is it important to know an areas magnetic declination?

Unlike the geographic poles, which are always in the same place, the magnetic poles change location throughout the history of earth. So when using a compass to map or explore the Earth's surface, you need to make a correction for the difference between geographic nor and magnetic north.


What is the magnetic declination for Missouri?

Zero. That's not precisely true, but if you really need a precise value you'd already know better than to ask what the declination was for an area as large as the state of Missouri. The agonic line (where the declination is precisely zero) does currently run through Missouri, so the value is less than a degree or two for essentially the whole state.


How do you adjust for magnetic declination when navigating with a compass?

To adjust for magnetic declination when navigating with a compass, you need to determine the angle between true north and magnetic north in your location. This angle varies depending on where you are on the Earth's surface. Once you know the declination angle, you can either add or subtract it from the compass reading to find the correct direction. This adjustment ensures that you are navigating accurately and heading in the right direction.

How do you align your compass to true north?

All compasses point to magnetic north, except when at the North or South Poles. Then the compass can do crazy things. Truth north can be found by placing your compass so the finger points along the N line on your map. Holding the compass in that position, turn your map so that the finger is aligned along the degree line on your map. You can tell the North Line as it is aligned with the edge of the map. The other line is your True North according to your position for your particular area.

It is important to know formulas of pi for circles like areas of a circle and its circumference


What is the optimun angle of declination?

Zero degrees! If the angle of declination is 0°, then magnetic north is exactly the same as true north, making it much easier to navigate. But really, there isn't any "optimum" angle. One angle is just as good as another as long as you know how to correct for it in the right way.


Why is it important for an actor to know stage areas?

Because he or she has to know which direction to turn, what direction others will come from, etc.
