In 3-5 sentences, describe how paleomagnetic evidence supports the theory that continents change position (drift) over time.(4 points)

Short Answer Rubric (4 points)

Answer 1

Paleomagnetic evidence supports the theory of continental drift by revealing the past positions and movements of continents. Through studying the magnetic properties of rocks, scientists have observed that the Earth's magnetic field has changed orientation over millions of years. This is reflected in the magnetic signatures recorded in rocks on different continents, which match up to form a continuous pattern when the continents are rearranged. This supports the idea that the continents were once joined together and have since moved apart.
