The stratosphere is the second major layer in the Earth's atmosphere. It is located above the troposphere and below the mesosphere. An interesting characteristic of this layer is that heat increases with altitude due to ultraviolet light being absorbed from the sun within the ozone layer.
One meter is 100 cm which implies 30 meters is 30*100 cm which is 3000 cm. So the continent has moved 3000 cm in 1000 years. So the distance traveled in one year will be 3000 cm divided by 1000 that is 3000/1000 which is 3cm/year So the rate at which a continent is traveling is 3 cm/year.

The correct answer is - D. It is impossible to dig through the ice on Antarctica.
Even though the technology is much more advanced nowadays than in the past, the extraction of the numerous natural resources from Antarctica is still pretty much impossible because of the ice cover over the continent.
On average, the ice is around 2 km thick on top of the landmass. Considering the fact that in order to get to the resources, the people will have to dig even more into the ground after they manage to break through the ice, makes it almost impossible, and not to mention economically unjustifiable.
