The entire outermost part of Earth is able to wander over the rest of the planet, and now researchers say in a new study detailed in the Nov. 8 issue of the journal Nature that they can explain how it can mysteriously return back the way it was. The planet's solid exterior — its crust and most of its mantle layer — at times drifts over its core. To envision this, imagine that a peach's flesh somehow became detached from the fruit's pit and was free to move about over it. These shifts can prove rather extreme. A person sitting on the Earth could have seen the pole apparently wander up to 50 degrees and then return close to its original location, all in tens of millions of years. Science news from NBCNews.

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
