[edit]Article Title: Inner Core Super-Rotation (New article)
Introduction:
- Inner core specs
- Basic description of compostion
- Size
- State
- Rotation of the Earth
- Rotation of the inner core with respect to the Earth
- Mention that it affects geodynamo and cycling
Evidence for inner core super rotation
- History of the discovery of inner core rotation
- Unitl 15 years ago, it was not thought the inner core was rotating at a different speed
- Geodynamo
- Convection
Seismic velocity data support
- Quantiative support
- Eastern vs western velocity discrepancies
- Why this suggests slower speed of rotation than before
Specific Facts
- Specific speed
- Unknowns in determining speed
- Other facts that can be known through determing the speed
Current Scientific Conclusion
- Slower than thought before
- Could be large changes in speed
- Could be more dynamic, in speed and structure
- Must likely be rotating to keep current models previously mentioned (geodynamo and convection)

Article Selection and Comments
[edit]Article: Inner Core, adding information about inner core super rotation
- Current information: three sentances about the inner core rotation
- Very little cited material listed about it
- Options
- Add to/edit paragraphs (2)
- New subsection (1) - enough information to do this I think
- New Section (3)
Alternative Article: Earth's Rotation
- Has no mention of inner core rotation
- Would have to create a whole sub-section
- Much more difficult and harder to tie together

Article evaluation
[edit]- Looks good
- Accurate
- More depth? Other subsections?
- Article is neurtral
- Not biased
- A few of the sources are questionable
- Only a few people have written about the topic
- Critical of the article
