The strike of a rock unit is the compass direction of a horizontal line on the rock surface, while the dip is the angle at which the rock unit is inclined from the horizontal plane. Together, strike and dip describe the orientation and slope of rock layers in relation to the Earth's surface.

To measure dip using a brunton compass, hold the compass horizontally, align the short leg with the dip direction on the rock surface, and read the dip angle from the compass dial. To measure strike, place the compass on the rock surface with the long edge pointing in the direction of maximum slope, and note the strike direction indicated by the compass needle.
The dip of the Earth's magnetic field varies because the field is not perfectly uniform and is influenced by the local geology of each region. Changes in the magnetic properties of the Earth's crust, as well as the distribution of magnetic minerals, can cause variations in the magnetic field strength and direction, resulting in different dip angles at different locations around the world.
