Earth's magnetic orientation is locked into the rock when the rock cools
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
There is nothing -_-

Earth's magnetic reversals are recorded in rocks that contain magnetized minerals, such as iron-bearing minerals like magnetite. When these minerals solidify and align with Earth's magnetic field, they preserve a record of the magnetic field at that time. Scientists can study these rocks to determine the timing and duration of past magnetic reversals.
Their evidence comes from rocks at earths surface.

Earth's magnetic pole reversals are recorded in rocks as they cool and solidify. When rocks form, they preserve the orientation of Earth's magnetic field at that time. By studying the magnetic alignment of rocks on the ocean floor, scientists have discovered patterns that support the theory of plate tectonics, such as the symmetrical magnetic striping on either side of mid-ocean ridges.
The Earth's magnetic reversals have been recorded in newly forming oceanic seafloor basalt by the orientation of magnetic minerals which become frozen in place as the magma hardens. When the next reversal occurs, it as well becomes part of the ocean floor magnetic record.
Paleomagnetism is the study of the Earth's magnetic field as recorded in rocks. When rocks form, they can lock in the orientation of the Earth's magnetic field at that time. By studying the magnetic orientation of rocks, scientists can determine the past positions of the Earth's magnetic poles, aiding in understanding continental drift and plate tectonics.

This is known as paleomagnetism.
intrusive rocks are formed within the earths surface from magma. extrusive rocks are formed from lava outside of earths surface
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
The magnetic orientation of rocks can be used to track the movement of continents by recording the direction and intensity of Earth's magnetic field at the time the rocks formed. When rocks solidify, they lock in the orientation of Earth's magnetic field. By comparing the magnetic orientation of rocks from different locations, geologists can determine how the continents have drifted over time.
