How does the continental drift hypothesis account for the apparent wandering of the poles?
The magnetic poles do move a bit, but stay mainly near the north and south geographic poles. As the continents move, though, different areas of crust overlay the magnetic poles, and the paleomagnetic markers (such as iron granules) point to where the pole WAS when they were deposited and then solidified into position. These "polar" crustal regions later move and the poles appear to have moved; actually, the crust has moved instead. For example, the north magnetic pole now is on an arctic island. In 100 milliion years that island may have been moved by plate tectonics to the equator, and the lava deposited in Yellowstone will point to that area.
Where can volcanoes occur?
most volcanoes are located along the boundaries of plate tectonics.They may form at divergant boundaries and convergant boundaries.May form below plate tectonicsMost volcanoes are created by destructive plate tectonics at the convergence of the boundaries of two continental plates. As the plates collide and rise together they form a mountain over a hot spot (a place where underground lava-"magma"- collects), the volcano will erupt once the pressure rises to a certain level. The eruption can take the form of a small vent where smoke and steam are released, or it can be a huge eruption where lava is released along with soot, ash, and poisonous gases. These other products of an eruption often are what cause more harm to people than the lava.A common location of these types of convergent/destructive plate boundaries is the "Pacific Ring of Fire", where about 75% of Earth's volcanoes are found.Volcanoes can also occur at hot spots, such as at the areas of the Hawaiian islands and Yellowstone in America. This type of volcano forms when magma from the mantle rises to Earth's surface through a certain spot in the middle of the plate (i.e., the Pacific Plate for the Hawaiian Islands). This hot spot is situated beneath the center of the plate, and the volcano above moves with the plate as it moves, but the hot spot stays in place. This causes the original volcano to become extinct as its move cuts it off from its magma source. A new volcano will then form above the hot spot again. This process repeats as the plate moves and a string of volcanoes will dot the surface of the plate as the movement continues away from the hot spot.Volcanoes usually occur where there are collision of the tectonic plates. There are 52 tectonic plates which either pull (gap and crack) or push (volcano). Volcanoes are actually tectonic plates which have magmas beneath their outer surface.between two plate boundariesVolcanoes typically are found at convergent boundaries and divergent boundaries, like the Ring of Fire around the Pacific Plate. Hot spots around the world account for the third place where volcanoes can occur.

How do hot spots and the plate tectonics theory account for the different ages of the Hawaiian Islands?
because
How do hot spot and the plate tectonics theory account for the different ages of the Hawaiian island?
it is because every island is formed at a different time when a volcano erupts so in theory if everything stayed the same except for the island in a million years or so the Hawaiian islands could in fact reach all the way to Japan or south America
