List three evidences you have that continental drift actually is occurring?

Answer 1

There is a phenomenon called 'magnetic banding' where rock preserves the orientation of the earth's magnetic field at the time it's created at constructive plate boundaries. The earth's magnetic field flips every so often in geological history, so we see bands of rock in the sea floor with alternating magnetic signatures. This indicates that the seafloor has spread and made new rock over time, and so the continents associated must have spread (and met in the middle at some point in the past.) Similarly, we see volcanism and earthquakes happen at destructive plate boundaries, suggesting plates are drifting and being pushed under one another, indicating that overall the plates are moving. Now we can put GPS markers all over the world and use satellites to accurately show how much certain plates have moved in a particular timeframe.

Answer 2

1. The matching shapes of Coastlines on opposite sides of the Atlantic Ocean, such as the fit between the coastlines of Africa and South America.
2. The distribution of similar fossils and rock formations on continents that are currently separated by oceans, suggesting that they were once connected.
3. Geological evidence, such as the alignment of mountain ranges and the presence of ancient glacial deposits found in regions that are now far apart.
