Why is it important to take declination into account of you are traveling with a compass?
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 declination on a map?
Declination on a map refers to the angular difference between true north (the North Pole) and magnetic north (the direction a compass needle points). This difference is important for accurate navigation with a compass, as it allows you to adjust your compass readings to align with the map.
What is The discrepancy between the orientation of a compass and true north known as?
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
What is the measure of the declination to the north?
Difference between Compass direction and True north.
How do you calculate magnetic declination?
The difference between True North and the direction that a magnetic compass points for a given location. Example: the magnetic declination for Seattle, Washington per the NOAA is 16° 55' east (as of 04/2010). This means that magnetic north is predicted at 16° 55'east of True North at that time.
What is the angle between the geographic North Pole and the direction in which a compass needle points is called magnetic?
The angle between the geographic North Pole and the direction in which a compass needle points is called magnetic declination. This angle varies depending on the location on Earth and can be used to adjust navigation using a compass.

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.
What is declination on a map?
Declination on a map refers to the angular difference between true north (the North Pole) and magnetic north (the direction a compass needle points). This difference is important for accurate navigation with a compass, as it allows you to adjust your compass readings to align with the map.
What is the angle that a compass needle deviates from true north?
The amount a compass needle deviates from true north is known as magnetic declination. This angle can vary depending on your location on Earth and is caused by variances in the Earth's magnetic field. It is important to adjust for magnetic declination when using a compass for accurate navigation.
Why is it important to know an area's magnetic declination?
Knowing an area's magnetic declination is important for accurate navigation using a magnetic compass. Magnetic declination indicates the angular difference between magnetic north and true north, helping to correct for compass errors. This information is crucial for precise orientation in outdoor activities such as hiking, camping, and boating.
What is The discrepancy between the orientation of a compass and true north known as?
The discrepancy between the orientation of a compass and true north is known as declination. It is caused by the difference between the Earth's magnetic field and its geographic North Pole. To navigate accurately, this declination value needs to be factored in when using a compass for navigation.
What is the measure of the declination to the north?
Difference between Compass direction and True north.
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 would you tell someone how to use a compass?
To use a compass, first hold it flat in your hand and make sure the needle is pointing north. Then, rotate yourself and the compass together until the red end of the needle aligns with the "N" on the dial. Your direction of travel is now indicated by the direction of the compass arrow. Remember to account for declination if necessary.
