Explain what paleomagnetism is and how it supports the theory of continental drift. *

the branch of geophysics concerned with the magnetism in rocks that was induced by the earth's magnetic field at the time of their form. The record of the strength and direction of Earth's magnetic field (paleomagnetism, or fossil magnetism) is an important source of our knowledge about the Earth's evolution throughout the entire geological history. This record is preserved by many rocks from the time of their formation.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
