Question

Q. What do you understand by the theory of ‘continental drift'? Discuss the prominent evidences in its support.

Answer 1

Continental drift is the theory that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.Today, the theory of continental drift has been replaced by the science of plate tectonics.  modern proponents of continental drift have amassed impressive geologic evidence to support their views. Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia. If these continents were once united around the south polar region, this glaciation would become explicable as a unified sequence of events in time and space.
