Drift Wood:
Polar wandering differs from continent to continent. But the poles for a specific time in geological history can be aligned through the various continents by envisaging the continents in different positions from those they now occupy. It is in this way that the progress of continental drift wood can be plotted. The results of this technique agree fairly well with other drift wood indicators such as sea-floor spreading and evidence of ancient climates shown by the rocks and their fossils. Palaeomagnetism is a powerful tool in continental drift wood research.icing wood If the damaged area is greater than is practicable cut out and replace the damaged wood. Remove all the ed wood and shape the surrounding area so you can match it new wood. Apply wood hardener to any remaining soft fibers. ;at exposed wood with a clear wood preservative and, if you lanning to paint, use pretreated wood to fill the hole. Other-treat your shaped piece with clear wood preservative before 3 it in place. It is best to cut the repair piece slightly too high so you can plane or sand it flush with the surrounding wood.
The implications of sea-floor spreading for the theory of continental drift wood are obvious; the mid-ocean ridges could be the points away from which the continents migrate. Movement of the sea floor, however, is at present only an observed fact; it does not provide us with an explanation of how solid continents can drift wood apart.
