How would you date a sample rock that you suspect as being one of the earliest on earth?
You would use a radioactive isotope with a long half life. Good luck!
What else can I help you with?
Which gas did Earth's earliest atmosphere lack?
Earth's earliest atmosphere lacked oxygen, and was primarily composed of gases like carbon dioxide, water vapor, nitrogen, and methane.
Why pieces of earth's earliest crust do not exist today?
Earth's earliest crust, which formed over 4 billion years ago, has been recycled through processes like subduction, where it is pulled back into the mantle. This constant recycling of Earth's crust, along with the effects of erosion and weathering, means that no original pieces of the earliest crust remain intact today.

What gases was most like present in Earth's earliest atmosphere?

Which geologic event occurred first?
The formation of the Earth is the earliest geologic event.
How would you date a sample of rock that you suspect being one of the earliest on Earth?
You would use a radioactive isotope with a long half life. Good luck!
What is measured by the pulling of gravity on a sample of matter?
The gravitational forces in each direction between the Earth and a sample of matterare equal. The force exerted on the sample by the Earth is what we call the "weight"of the sample. The force exerted by the sample on the Earth is the one that nobodyever mentions, but it's also equal to the weight of the sample. In other words, theweight of the sample on Earth is equal to the weight of the Earth on the sample.
When did the earliest organisims appear on Earth?
Nobody really knows when the earliest organisms were on Earth. It was definitely more than a million years ago.
When is the earliest trace of humans on earth?
The earliest traces of humans on Earth date back to about 2.8 million years ago, with the discovery of hominin fossils in Ethiopia being some of the earliest evidence of human ancestors. These early hominins were part of the genus Australopithecus, such as "Lucy" (Australopithecus afarensis), and represent our early evolutionary history.
