What is a compass north south east and west?
It is called a mariners compass, it is a instrument that shows the North, east, West and South, and is used by pilots and the sailors.
Which direction has a compass bearing of 22.5?
North north east
How does earth magnetic field affect a compass?
The earth's magnetic field acts upon the magnetic material of the compass needle, causing it to align to the field. Thus, the compass appears to point North, which is "magnetic north". Magnetic north and "true north" are about 300 miles apart.
When a compass rose indicates only one direction they use a compass rose indicates two directions usually indicates north and the opposite direction which is?
If the question is asking what is opposite north on a compass then the answer is south.
How do sailors navigate the ocean without a compass?
Since the needle on the compass is orient to due north the compass was used in concert with a sextant to prepare route maps. The compasses were used to make sure that north on the map was properly oriented.
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.
What is the angle between geographic north and the north to which a compass needle points?
The sum of variation and deviation. The angle of magnetic declination, or magnetic variation, is the angle between the local magnetic field lines with which a magnetic compass needle lines up and the direction of true north, the north axis point of Earth. In the U.S., that angle varies between 0 degrees and about 20 degrees and also varies over time.The difference between "true" north and "magnetic" north is called "magnetic variation", which is often abbreviated as "mag var".The north magnetic pole is in northern Canada, but is continually (although slowly) moving. Topographical or navigational maps are generally overprinted with "mag var" lines and the amount of correction.
A tool for mesuring the size of an angle?
A compass. This is not the same as a compass used to determine the direction of North.
Is the angle between geographic north and the north to which a compass needle points?

What is the purpose for a needle on a compass?
to point the right direction ***correction by cw - the needle always points north.
Does a compass point to the geographic north pole?
No. The compass needle points toward the magnetic north pole.
Why is it important to consider the angle of correction to the North Pole when setting up a sundial?
Assuming you are using a compass to align the sundial, it will point to the Magnetic North Pole. The Earth rotates about the True North Pole, which is not in the same location. By obtaining the magnetic variation for your locale, you can make the adjustment and have an accurate set up.
Does the magnetic compass always point in a northern direction when placed on the earth?
No. The true north pole and the magnetic north pole are in different locations. The compass will point at the magnetic north pole. If you happened to be somewhere between the two north poles, the compass will point exactly backwards!
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.
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.
A way to find the variation from true north?
To find the variation from true north, you can use a magnetic compass to determine the magnetic north and then calculate the angle between the magnetic north and the true north. This angle is known as the magnetic declination or variation. Many maps and GPS devices provide information about the current magnetic declination in a specific location.
