In the early Paleozoic,the majority of continental landmass was found in the southern hemisphere,and now the majority of continental landmass is found in the northern hemisphere.Why might this be?
A) rotation of the poles of the Earth's axis
B) the subduction of the former southern hemispheric supercontinent and igneous and tectonic construction of the newer northern hemisphere landmasses
C) conservation of energy, following the collision of an approximate 8-km-wide meteorite with Earth at the K-T boundary event
D) mantle convection, which rifted apart the southern supercontinent and caused most pieces of it to migrate northward
