- Franklin D. Roosevelt (allthetropes.org)
Franklin Delano Roosevelt (1882-1945) was the longest serving President in US History, serving three full terms and starting his fourth when he died. No other President had even won a third term (a couple had tried — Grant and T.R. — but none were elected). And, thanks to the 22nd Amendment, no President since will be able to challenge his length of service (barring the very unlikely event of the 22nd being repealed).
- Geological formation (Wikipedia)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers.
