According to the fossil record, life on Earth evolved 3.5-4.28 billion years ago in the form of what? Primitive bacteria that lived in rocks on the deep ocean floor. To investigate the origins of life on Earth, scientist Stanley Miller set up an experiment.
As the earth's history was formed by a collision that led to the formation of the moon that took place about some 4 billion years ago and the earth was a then a blob of molten rock with just a thin solid film on its outer surface.
<u>What can be inferred about the different density of the earth is the earth atmospheric at that time was warm and solar radiation with a relative density and the oceanic crust has relatively more dense matter settled down and in the process known as the planetary differentiation.</u>
As lake quail is a dammed river and lies directly over the San Andrea fault and transform boundary with the North American plate on the northward side and the pacific plate on the southern side and a stream rises in the Pine Valley Mountains and flows to the southeasterly direction.
The pacific plate is moving in the northwest direction due to the seafloor spreading from the eastern pacific rise. while the North America is being pushed to the southwest due to the spreading of the seafloor in the mid-Atlantic ridge.
