The history of the Earth can be organized chronologically according to the geologic time scale, which is split into intervals based on stratigraphic analysis. [2] [21] The following five timelines show the geologic time scale to scale. The first shows the entire time from the formation of the Earth to the present, but this gives little space ...
The Clean Air Act is passed in the United States, with subsequent amendments in 1970, 1977 and 1990. 1974 World population reached 4 billion. [23] 1970s 2010s Deindustrialization occurs in the Midwest and then much of the United States, as manufacturing industries (and their pollution) move to China and other Asian countries. 1980
The Earth is destroyed by the Sun at "high noon", though animals and plants come to an end by 5:00 am, meaning that the time that Earth can remain habitable to animals is very short, lasting only just 1 billion years, with the present day being the halfway point through that relatively short time.
So to understand how we came to exist on planet Earth, we'll need to know how Earth managed to stay fit for life for billions of years. Earth has been habitable for billions of years ...

The earliest Earth crust probably forms similarly out of similar material. On Earth the pluvial period starts, in which the Earth's crust cools enough to let oceans form. c. 4,404 Ma – First known mineral, found at Jack Hills in Western Australia. Detrital zircons show presence of a solid crust and liquid water.
These timelines of world history detail recorded events since the creation of writing roughly 5000 years ago to the present day. For events from c. 3200 BC – c. 500 see: Timeline of ancient history; For events from c. 500 – c. 1499, see: Timeline of post-classical history; For events from c. 1500, see: Timelines of modern history
In 50 billion years, if the Earth and Moon are not engulfed by the Sun, they will become tidelocked into a larger, stable orbit, with each showing only one face to the other. [ 105 ] [ 106 ] [ 107 ] Thereafter, the tidal action of the Sun will extract angular momentum from the system, causing the orbit of the Moon to decay and the Earth's ...
