The order of units of geologic time from longest to shortest is: eon, era, period, epoch.
eon>era>period
Eon, epoch, period, era
The geologic time intervals from longest to shortest are eon, era, period, epoch, and age. This hierarchical sequence represents the largest divisions (eons) to the smallest subdivisions (ages) of Earth's history.
The geologic time scale is divided into four eons: Hadean, Archean, Proterozoic, and Phanerozoic. Phanerozoic eon is the most recent and divided into three eras: Paleozoic, Mesozoic, and Cenozoic. Each era is further divided into periods, epochs, and ages, with the ages being the shortest divisions of time on the geologic time scale.
The order of units of geologic time from longest to shortest is: eon, era, period, epoch.

Shortest: 7.995 m Longest: 8.005 m.
Eon, epoch, period, era
The geologic time intervals from longest to shortest are eon, era, period, epoch, and age. This hierarchical sequence represents the largest divisions (eons) to the smallest subdivisions (ages) of Earth's history.
The units of geologic time, from shortest to longest, are as follows: epoch, period, era, and eon. An epoch is the smallest unit, representing a subdivision of a period, which is a division of an era. Eras are then grouped into eons, the largest units of geologic time that encompass significant spans of Earth's history.
Summer solstice the days in the northern hemisphere are longest and the nights are shortest. But in the winter solstice in the northern hemisphere the days are shortest and the nights are longest.
Summer solstice the days in the northern hemisphere are longest and the nights are shortest. But in the winter solstice in the northern hemisphere the days are shortest and the nights are longest.
The shortest known gestation period is the Virginian opossum, which is 12 days. The longest period belongs to the Indian elephant, which has a gestation period of 22 months.
The sum of the squares of the lengths of the two shortest sides is equal to the square of the longest side.
Because the sum of the shortest sides is less than the longest side and in order to construct a triangle the sum of its shortest sides must be greater than its longest side.
The longest wavelength corresponds to long wave radio, I think the longest used is about 2000 meters. The shortest are gamma rays, which occur in radioactivity, these are from about 10-11 meters down.
