As it turns out, the Moon is truly a whole new world, with rocks and surface features that provide a record of events that occurred during the first billion years of the solar system.
This record is not preserved on Earth because all rocks formed during the first 800 million years of Earth's history were recycled back into the interior.
Nevertheless, the original terminology to distinguish Precambrian rocks from all younger rocks is still used for subdividing within 50 degrees.
Most fossil carbonates, evaporites, phosphorites, and red beds of Phanerozoic age dating back to the Cambrian have a similar bimodal distribution with respect to their paleoequators.
Earth's spin or rotation is a relic of its origin as a hot, spinning mass when it was first formed.
Earth science or geology is the science of the Earth.
During the long course of Precambrian time, the climatic conditions of the Earth changed considerably.
Evidence of this can be seen in the sedimentary record, which documents appreciable changes in the composition of the atmosphere and oceans over time.
Thus, it can be inferred that the extensive evaporites dating to 3.5 billion years ago from the Pilbara region of Western Australia could not have been formed within or near the poles.When the star that we call our Sun condensed out of a swirling cloud of hot interstellar gas, some material remained in orbit around the newly forming star.That orbiting material consisted of hot chunks of rock and frozen liquids called "planetisimals".From these were gradually formed several (nine that we know of) planets including Earth.The planets - including Earth - still move in relatively stable orbits around the sun.
