In 3-5 sentences, describe how paleomagnetic evidence supports the theory that continents change position (drift) over time.(4 points)
Answered by GPT 3.5
They were found in glacial deposits. This indicates that the plants were once in a different location, as glaciers are formed when ice accumulates on land and moves slowly over time. The presence of plant fossils in these glacial deposits suggests that the plants originated elsewhere and were transported to Svalbard as the continents drifted.

Paleomagnetic evidence supports the theory of continental drift by showing the movement of continents over time. Rocks contain tiny magnetic minerals that align themselves with the Earth's magnetic field at the time of their formation. As these rocks solidify and become part of the Earth's crust, their magnetic orientations are preserved. By studying the magnetic properties of rocks from different continents, scientists have found that magnetic patterns match across continents, providing evidence that they were once connected. This supports the idea that continents have moved from their original positions, supporting the theory of continental drift.
