Earth after first form.
Now, I will discuss all the events that occurred on Earth from the beginning of the creation until now.
In the aftermath of the formation of the Earth, all life did not yet exist at all, there was only a fiery and hot rock planet. The first temperature created can equal the temperature of the Sun today, which is around 4,500-5,000°C. And at this time too, the Earth is often hit by rocks from space, some even up to the size of the size of the planet Mars. Want to know what the name of the rocks? And how it goes? Let us discuss.
Formation of the Earth. The Earth forms from a protoplanetary diak around a young Sun.
4,517 Ba:
Formation of the Moon. The Giant Impact Hypothesis postulates that a Mars-sized planet named Theia collided with the Earth in a glancing blow, depositing iron in the Earth while the debris coalesced to form the Moon. The Moon would stabilized Earth's rotation and Introduce tides to the oceans.
4,500 Ma:
Formation of the primordial soup. The oceans of the early Earth are thought to have contained many complex organic molecules, brought to the surface by meteorite impact.
4,410 Ma:
Latest appearance of water. By this time, water could be found Earth's
4,401 Ma:
Oldesr dated mineral. Zircon crystals found in the Narryer Gneiss Terrane in Australia are among some of the few remaining crystal material from the Hadean Eon.
4,280 Ma:
Earliest date of first life. Indirect evidance point to life appearing as soon as Earth becme habitable. Early life likely around undersea vents, using the material as a source for metabolism.
4,100 Ma:
Late Heavy Bombardment begins. Instability in the orbits of the outer planets causes a drastic shift in orbits, increasing thr amount of asteorid impacts through out the Solar System
4,030 Ma:
Oldest known intact crust. The Acasta Gneiss in Canada, the oldest knoen exposed rocks, form.
4,000 Ma:
Formation of the magnetic field. The magnetic field was active by this time, though about 10-50% of this strength today.
