Since the continents are moving about 2cm a year, what would happen in 1 million year?

Question

Basically all i want to know is where the continents will be, and how life would change in 1 million years, from the continents moving.

Answer 1

In a million years it wouldn't be a major change, something like a dozen miles movement. Here is an animation that takes the average plate motion observed over the past one million years and projects it 100 million years into the future in 10 million year increments. The model does not account for continental collisions, subduction, or sea-floor spreading; it simply shows where continents would end up if they were to keep moving in their current directions at their current rates.

Answer 2

Well you would have to observe the direction that the continents and the oceanic plates are currently moving. Of course, that is subject to change at anytime during 1 million years. So it would be difficult to accurately predict their placement. It can be done but its not perfect. Also, if directions can change, so can rates of movement. So really its nothing more than an educated guess. Prior continental arrangements are educated guesses but we have fossil and rock evidence to help us reconstruct things.
