Some of the oldest rocks ever found have been estimated to be about 3.5 billion years old. Is it likely that these rocks were present when Earth was first formed?
No, rock material is constantly recycled on Earth as rock is melted into magma.
What era was earth first formed Cenozoic Mesozoic Paleozoic or Precambrian PLEASE HELP?
The earth first formed at the beginning of the Precambrian supereon which spans a very large period of time from 4,567 million years ago, through to 542 million years ago.The beginning of the Precambrian where Earth formed is known as the Hadean eon, stretching from 4.7 Ga (billion years ago) and ended roughly 3.8 billion years ago.
When earth formed?
4.5 billion years ago
Where was the first volcano in world?
There is no way of knowing. The first volcanoes would have formed when earth's crust first formed over 4 billion years ago. Apart from some small zircon crystals any features from that long ago have been destroed by geologic processes.
What do scientist believe that when the earth was first formed its crust was made of metamorphic rock?
Sorry, when the earth first formed it was entirely molten, so the first solid rock on earth was igneous.
Some of the oldest rocks ever found have been estimated to be about 3.9 billion years old Is it likely that these rocks were present when Earth was first formed?
No. The fact that some of the oldest Earth rocks are over 4 billion years old indicates that Earth was in a molten state for around 300 million years. The first rocks would have formed on Earth from this molten material.
When was the earth first formed?
The earth was first formed around 4.54 billion years ago. But lots of different people say lots of different things.
Where were the first organic compounds on earth probably formed?
Probably 4 billion years (out of 4.5 billion total), but the simplest ones don't leave much of a record. ------------------------------------------------------------------------------------------------------------- Simple organic compounds can be seen is space dust in distant nebulae, an are to be found in certain (contrite) meteorites which formed in the planetary nebular from which the earth condensed. Therefore they must have been present on earth as it formed.

No, rock material is constantly recycled on Earth as rock is melted into magma.
What came first the planets formed or the earth?
at present the theory is that all of the planets that make up the solar system were formed at the same time when the Solar System condensed out of a cloud of gas about 4.5-4.7 billion years ago.
Did earth first oceans form?
It was about 4 billion years ago, that the Earths oceans formed
When was planet Earth first found?
The earth, along with the rest of the solar system, was formed approximately 4.5 billion years ago.
Look earth after five billion years ago?
Earth did not exist 5 billion years ago. What would become Earth was part of a collapsing cloud of gas and dust that would eventually form the solar system. Earth itself formed about 4.55 billion years ago. When it first formed it was made largely of molten rock.
What came first the earth or everything else in the universe?
Not too sure about everything else, but the Universe was created about 13.73 billion years ago. Our Galaxy - the Milky Way was formed about 13.2 billion years ago. Our Solar System, which includes the Earth was formed about 4.6 billion years ago.
How many years were prokaryotes present on earth before the eukaryotes?
* 3.5 billion years ago the first life arose: prokaryotic bacteria * 1.5 billion years ago eukaryotic cells arose Therefore, prokaryotes were present on earth for 2 billion years prior to the emergence of eukaryotic life.
How long ago was the first form of earth?
We believe that our solar system, including the Sun, Earth and all the other planets, formed about 4.5 billion years ago
