Other techniques included sampling mud from the seafloor (China), analyzing the flight path of birds, and observing wind, sea debris, and sea state (Polynesia and elsewhere). Objects that have been understood as having been used for navigation by measuring the angles between celestial objects, were discovered in the Indus Valley site of Lothal. The Norse are believed to have used a type of sun compass to locate true north. On cloudy days, the Vikings may have used cordierite or some other birefringent crystal to determine the sun's direction and elevation from the polarization of daylight; their astronomical knowledge was sufficient to let them use this information to determine their proper heading. The invention of the compass made it possible to determine a heading when the sky was overcast or foggy, and when landmarks were not in sight. This enabled mariners to navigate safely far from land, increasing sea trade, and contributing to the Age of Discovery.

- The earth’s magnetic fields are essential to the operation of the compass, so it is important to understand the structure of the earth to know how they work.

Due to the pressure and resulting heat, these elements move in various direct…
