- The Longest Era of Earths History is Paleoproterozoic Era lasting 900 million years. The largest unit of time in relation to Earth's history is the super-eon. Super-eons are … divided into eons. Eons in turn are divided into eras, eras are divided into periods, periods into Epochs and Epochs in Ages.

Beetlejuice Beetlejuice is a 1988 American comedy-fantasy film directed by Tim Burton, produced by The Geffen Film Company and distributed by Warner Bros. The plot revolves around a recently deceased young couple who become ghosts haunting their former home, and an obnoxious, devious ghost named Betelgeuse from the Netherworld who tries to scare away the new inhabitants permanently. After the success of Pee-wee's Big Adventure, Burton was sent several scripts and became disheartened by their lack of imagina

Geologic time scale British geologists were also responsible for the grouping of periods into Eras and the subdivision of the Tertiary and Quaternary periods into epochs. In 1841 John Phillips published the first global geological time scale based on the types of fossils found in each era.

What is the largest unit of measurement for distance? exists and is an alternate of . The largest unit of distance that I'm aware of is the gigaparsec (Gpc) or 1 billion parsecs. Astronomers use a method called parallax to measure the distance to some stars, and an object with a parallax of one second is said to be 1 parsec away. This distance is 3.09x1016 meters, so a gigaparsec is 3.09x1025 meters.

Spirifer  [show article only]hover over links in text for more info About the geologic time scale divisions. The geologic history of the Earth is broken up into hierarchical chunks of time. From largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages. All of these are displayed in the portion of the geologic time scale shown below. The Phanerozoic Eon represents the time during which the majority of macroscopic organisms — algae, fungi, plants and animals — lived. When first proposed as a division of geologic time, the beginning of the Phanerozoic (542.0 million years ago)* was thought to coincide with the beginning of life.

Measuring the Size of an Earthquake These factors have led to the definition of a new magnitude scale M W, based on seismic moment, where M W = 2/3 log 10 (M O) - 10.7 . The two largest reported moments are 2.5 X 10 30 dyn·cm (dyne·centimeters) for the 1960 Chile earthquake (M S 8.5; M W 9.6) and 7.5 X 10 29 dyn·cm for the 1964 Alaska earthquake (M S 8.3; M W 9.2).

- It's not a brilliant question you haven't said what scale you're looking at - Cosmic, Geologic, etc, Geological time is divided as follows: 1  Hadean 800 million years. 2  Archean 1300 million years. 3  Proterozoic 1958 million years. 4  Phanerozoic 542 million years. 5  Paleozoic 291 million years.  Mesozoic 184.5 million years.

Geological Time Geological Time. The time scale at left is both a reference and a key to the display cases at the museum ­ click on a geologic period to go to that case. Note that in the United States it is common to break the Carboniferous into two periods, the Pennsylvanian and the Mississippian, as is done in our museum.

Geologic time scale The following four timelines show the geologic time scale. The first shows the entire time from the formation of the Earth to the present, but this compresses the most recent eon. Therefore, the second scale shows the most recent eon with an expanded scale. The second scale compresses the most recent era, so the most recent era is expanded in the third scale.

- The dates shown were compiled from several available sources. Table 1 shows some important events in Earth history, presented in the order in which they occurred. The data are also shown on the scale of a calendar year. When geologic time is compressed to the scale of a calendar year, 1 second equals about 146 years. At this scale, World War II began about 0.4 second before midnight on December 31; because of rounding, this is shown as midnight of the new year. On the back of this sheet is a chart showing the geologic eras, systems, and series; the oldest is at the bottom.

Is there a metric system unit of time? The International System of Units (SI) or the metric system defines a base unit of time as a second (s). The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom.

Physical Units The standard units are the Systeme Internationale or SI units. The primary SI units for mechanics are the kilogram (mass), the meter (length) and the second (time). However if the units for these quantities in any consistent set of units are denoted by M, L, and T, then the scheme of mechanical relationships can be sketched out.

- So let's recap about the geologic time scale and how its divisions fit together. Epochs are the smallest divisions. Many epochs make up a period, many periods make up an era, and many eras make up an eon.
