Understanding Magnetic Declination
Magnetic declination, also known as magnetic variation, refers to the angle between magnetic north (the direction a compass points) and true north (the direction along the Earth's surface towards the geographic North Pole). This angle varies by location and changes over time due to shifts in the Earth's magnetic field.
The Isogon Explained
The line that connects points of equal magnetic declination is known as an **isogon**. Here’s why it’s significant:
Other Terms for Context
To clarify the other options in the question:
Conclusion
In summary, the correct answer to the question regarding the line connecting points of zero magnetic declination is indeed option **B**: isogon. This concept is essential for those in fields such as navigation, geology, and meteorology, as it aids in understanding and utilizing the Earth's magnetic properties effectively.

The Isogon Explained
The line that connects points of equal magnetic declination is known as an **isogon**. Here’s why it’s significant:
- Definition: An isogon is a contour line on a map representing locations where the magnetic declination is the same.
- Importance in Navigation: Understanding isogons is crucial for navigation, as they help navigators correct compass readings to account for declination.
- Mapping Magnetic Fields: Isogons are used in geomagnetic surveys and charts to visualize magnetic field variations across different geographical areas.
Other Terms for Context
To clarify the other options in the question:
- Isoneph: Lines connecting areas of equal cloudiness.
- Isohyet: Lines depicting areas of equal rainfall.
- Isotherm: Lines connecting points of equal temperature.
Conclusion
In summary, the correct answer to the question regarding the line connecting points of zero magnetic declination is indeed option **B**: isogon. This concept is essential for those in fields such as navigation, geology, and meteorology, as it aids in understanding and utilizing the Earth's magnetic properties effectively.
