Hadean Era

Hadean Era

The Moon

During the earths formation 4.5 billion years ago, other smaller plantary bodies were also growing. One of these hit earth late in earths growing process. A small piece of the debris started to orbiting the earth. The earth has a large iron core because, by the time the collison happened, the iron had already drained to the earths core. Therefore during the blast, the debris was rocky mantles without iron.

Earth

Nebular Theory

The Moon

There have been many evidences found from the hadean era, one is the trace of Carbon minerals were found in 4.1 billion year old rocks, also the finding of zircon crystals from western Australia.

Earth is the thrid planet from the sun, and the densest planet in the solar system. It is also the only known planet in the milky way galaxy to harbour life. Earth is dated back to being formed in the Hadean eon, about 4.6 billion years ago.

One more theory is that the moon is a sisterworld to the earth, and formed when the earth did but this theory lacks explaination of lack of Iron.

Another one is that the moon formed somewhere else in the solar system but this fails because the lunar rocks have the same isotopes as Earth

It has been theorized that 4.6 Billion years ago, after the big Bang had receded a large cloud full of dust and gas collidied with planetesmals( small rocks) which later formed planets. This explained how the earth is today, because of the hot cloud colliding creating heat and energy, which is now seen in the inner core of the earth, also as it collided with circular objects it created for a circular planet.

Evidence

The Moon has exactly the same oxygen isotope composition as the earth, whereas other parts of the solar system have different oxygen isotopes. This shows how composition of earth and the moon occured similar times.

Earth during the Hadean era was going through a process of birth, as it was starting to develop like an evolution of the human person. It became together because of the joining of particles of different elements. After the big bang had proceded. The earths structure was really hot, and filled with lava and at that time, earth did not have developed an atmosphere to protect it from asteriods , as outside objects constructed earths atmosphere due to clashes resulting in heat expansion. This can be connected today as a infant does not have much of a defensive system or intelligence compared to an adolescence . To add on, this paragraph explained the condition of earth's atmosphere and surface, the precence of water during that time was sustained, because of the exponentially growing heat, liquid water was precence but to some consent.

Late Heavy Bombardment

The Moon

The "Late Heavy Bomberdment" as seen in many sifi movies to illustrate danger. LHB happened about 3. 8 Billion years ago. It was when a large series of asteriods were colliding with the planets in the milky way galaxy. This is connected with the nebular theory, as it is theorized that about 4.6 billion years ago, a large cloud of dust and gas collided with small terrestial planets(Asteriod) which are now known as Earth, mars etc.

The origin of the moon can also be explained as during the hadean eon, because the tides were about 300m, and this proves the moon, because it has been theorized the the universe is expanding and so is the moon, because the moon controls the tides because of the gravitational attraction between the moon and the earth.

The Moon

Another proof of the origin of the moon is that, since the moon was formed. Earth's rotation has been slowing down due to the tidal effects of the moon. Also, the expanding distance between the moon and earth according to Hubble's law explains the origin of the moon

During this period there was no known precence of life as it was very hot for life. Also the days were about 6 hrs, and it was very hot aswell because of the lack of coating in the atmosphere
