Write everything that you can remember learning in the Earth’s History Unit. Use only your own words and add as much detail as you can. Remember to include what you learned about fossils, relative dating, absolute dating, and geological time.

To understand this little-known period, the following factors have to be considered: the age of formation at 4.6 billion years ago, the processes in operation until 4.3 billion years ago, the bombardment of Earth by meteorites, and the earliest zircon crystals.

Explanation:

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. ... While the Earth was in its earliest stage (Early Earth), a giant impact collision with a planet-sized body named Theia is thought to have formed the Moon.For example, the entire age of the earth is divided into four eons: the Hadean Eon, the Archean Eon, the Proterozoic Eon, and the Phanerozoic Eon. These four eons are further subdivided into eras
