Glacial Deposits

During the ice age which occurred many million years ago, ice and glaciers were widely spread from the north and south poles. when a glacier moves past a smooth rock, it leaves behind deep scratches and deposits sediments that it has collected which can be identified, dated and traced to its original place.
300 million years ago, the Palaeozoic glaciation took place. The glaciers left scratches on rocks, which today are several continents and far away from eachother, the poles and are now positioned on the equator.
with the continents such great distances apart, it would have been impossible for this to happen unless they are all  realigned and moved towards the south pole. with this done, the glacial positions would be more reasonable.
