I dont know?check a better website! seriously!
it has been for 90%
The Earth never became round. It has always been round in shape since it was formed at the beginning of time.
A fissure I think, been a long time since I did geography though
The Hadean Eon, the earliest time interval, was when the Earth was cooling, and continents and oceans formed. Lifeforms are thought to have appeared in the following eon, the Archean Eon.(eras are a much smaller time interval, and the Hadean is not normally subdivided into these)
it was formed from extreme pressure for a long time under the earth.
no one knows exactly how the moon was formed for sure, but the most accepted theory is that the moon formed a long time ago from a collision between a `mars` sized body and the Earth. Around 4.5 billion years ago the solar system was in its infancy and there was still a lot of debris in orbit around the sun. Over time, this clumped together to form the planets and moons, through a lot of collisions. It is thought that a Mars sized body smashed into what would become the Earth (which would have been very unlike the Earth we know today). The object would have ripped apart, nearly ripping the Earth apart also, but over time the debris is thought to have recollected as it went into orbit around the Earth to become the moon.
The Solar System is about 4.6 billion years old; the Earth formed around that time, and has been orbiting the Sun, and rotating, since then.Note that Earth's rotation has been slowing down over time, due to tidal forces, mainly from the Moon.
Yes!!! It does it all the time; it is called 'light'.
The moon formed from the debris resulting from the impact of a Mars sized body with the nascent earth, a little more than 4.5 billion years ago. The moon would have formed quickly, within just a thousand years of that impact, and less than half the distance at which it currently is.
Yes
Geologists can't use rocks from Earth to determine the planet's age because those rocks have all been recycled through the rock cycle over time. This means that the original rocks from when Earth formed no longer exist. Instead, geologists use radiometric dating of rocks from Earth's surface to estimate its age.
When Earth formed, it was initially composed of gases such as hydrogen, helium, methane, and ammonia. Over time, these gases gradually dissipated into space or were absorbed into the planet's interior. The gases released from the Earth's interior during volcanic activity contributed to the formation of the early atmosphere.
