What is the approximate magnetic declination in central Texas?

3 degrees west
7 degrees east
9 degrees west
5 degrees east

The correct answer is: 7 degrees east

The approximate magnetic declination in central Texas is indeed around 7 degrees east. Magnetic declination refers to the angle between magnetic north (the direction a magnetic compass points) and true north (the direction along the Earth's surface towards the geographic North Pole). In central Texas, the magnetic declination value indicates that magnetic north is located to the east of true north. This information is crucial for surveyors and navigators who need to correct for declination when using a compass for precise heading and location placements. When planning any surveying project or navigation in the area, it is vital to account for this declination, as failing to do so could lead to significant errors in measurement and placement. The value can change over time due to variations in the Earth's magnetic field, which is why it's important to consult updated sources for the most accurate declination when conducting surveys.
