As per the concept of plate tectonics, The continents are like rock plates moving on the magma underneath it and magnetism is a part of it.
As we know Earth spin on its axis, this interaction of Earth's spin and magnetic material inside the Earth creates a magnetic field from North to South pole.
When hot material inside the Earth cool, it solidify and the magnetic material form crystals which align themselves along the Earth's magnetic field.
Hence by this way Earth's magnetic pole reversal provide evidence for plate tectonics.
Newton's first law of motion states that an object at rest will remain at rest and an object in motion will remain in motion unless it is acted on by an unbalanced force. Using unbalanced forces to control the motion of a skateboard demonstrates Newton's first law of motion.
