Origin stuff from 50 million years after the solar system formation 4.5 billion years ago, is still being extruded, exploded (or created, transformed) on our planets surface.
Earth's mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth's early history long ago. But a new study of volcanic rocks that recently erupted from volcanoes in Hawaii and Samoa reveals surprising geochemical anomalies - the 'fingerprints' of conditions that existed shortly after the planet formed.

With relatively near genesis material still found to be coming out from the surface is less and less of the planets inner material recycled and regurgitated?
Ptolemy and Johannes Kepler appeared to have recorded the wrong latitude and longitude for various ancient cities. Or did they?
Edmund Halley, he of the comet fame, suggested this was due to changes in the Earths/Moons rotation properties. Has relatively recent movement of the Earth's continents moved the locations of ancient cities?
Edmund Halley (1695, p. 174), as part of a discussion of the identity and location of ancient cities relative to the geography of his time, explained discrepancies in recorded latitudes as a "change in the axis of the Earth" and longitudes (based on lunar positions) as evidence that "the Moon's motion does accelerate".
The latitude discrepancies were probably errors, and the longitude discrepancies are more correctly interpreted as an equivalent deceleration of Earth spin rate, but Halley clearly did raise
the possibility that Earth - Sun - Moon relationships need not be fixed as had formerly been supposed.

Another painful blow and bite for plate tectonics theory and especially the very visually bizarre and seemingly impossible ultra rapid movement of the Indian Plate? Also for the idea of the supercontinent Gondwana and its breakup?
And all this trouble for and evidence against plate tectonics from one of the smallest and most annoying insects on the planet, the dreaded swarming biting midge?
India gradually drifted away from Africa and Madagascar towards the north and collided with the Eurasian plate. Scientists assumed for a long time that the subcontinent was largely isolated during its long journey through the ocean and unique species of plants and animals were therefore able to develop on it. However, paleontologists at the University of Bonn are now showing using tiny midges encased in amber that there must have been a connection between the apparently cut off India and Europe and Asia around 54 million years ago that enabled the creatures to move around.

Is there a possibility that an expanding Earth may have caused a dramatic climate change in our past?
Especially if there was an accelerated period of a growing planet?
Such as H G Owen slow expansion hypothesis or even an or multiple rapid and catastrophic planet expansions that would perhaps also explain Darwin's Dilemma and mysterious periods of relatively ultra quick orogeny (mountain building)?
What would be the effects of an Expanding Earth or a Growing Earth? What changes would it create?
What physical differences would an expanding in size planet have? How would it effect the flora and fauna on our planet?
Would a globe growing in weight/mass have a measurable and observable impact on human life on Earth?
How would our environment change if the planet did change its physical data set due to increases in stuff? Continue reading
The surface of our planet is going to mapped in much finer detail as scientists look to find warping of the crustal rock.
The aim of the Sentinel/COMET project is to detect earthquake and volcano movements.
But could the data be used as evidence to prove or deny the Growing Earth and Expanding Earth theories? Or will it always depend on your interpretation of the data?
To be really effective, the team's maps need to be sensitive to movements of about 1mm per year over 100km ... As a proof of principle - and to give an example of what the new system can do - the COMET group showed off its maps of Turkey at AGU.
These capture the 20-25mm/year westwards march of the Anatolian plateau relative to Eurasia.

The new winner of the oldest fossils on Earth have been discovered and dated but their survival is a real issue for plate tectonics.
The Greenland Isua stromatolites, microbe communities that lived on the sea floor, have been found in Greenland's Isua greenstone belt and these microbes are being dated as 3700 million years old. Our planet in theory being 4500 million years old.
This also suggests that life forms were already thriving only 500 million years after the planet was formed.
Are the North American mountain building periods (orogeny) evidence that sections of the planets surface can grow upwards?
The Laramide orogeny, a mountain building period mainly in the North America continent, has puzzling geological features including upward thrusts, wedges and intrusions. The Nevadan orogeny was an even bigger event.
It is now suggested that these events of parts of the Earth growing upwards were actually multiple events and not just a one of period.
Why do you seem to get hill and mountain ranges that abruptly rise out of the ground, yet do not seem to effect the level ground close to them?
Some scientists have suggested, due to the totally geology theory surprising visual evidence that was not predicted, that Pluto may be expanding.
Similar cracks, fissures, rifts, cliffs, escarpments, geological features on Mercury, due to pre existing theories, have scientists suggesting that planet Mercury is shrinking. Mercury is a tiny planet and was considered geological dead before recent findings.
Planet Earth, one of the most geological active, energetic, electromagnetically active planets in our solar system is absolutely stable. If you suggest the idea that similar geological features on our planet means it has or is expanding or then you are a crackpot dealing in pseudoscience. Fact - the geology is settled.
If planet Earth (and others) have expanded could they have periods of expansion spurts with reduced or non growth episodes between?
Planets do not have to grow continuously. If there is such a thing as an expanding Earth and expanding planets this goes against standard science.
A start/stop expansion cycle is an acceptable proposal for those interested in exploring all the possibilities of why the continental plates appear to fit together on a smaller globe.
A recent proposal by a planetary scientist after a new plate tectonics simulation suggests that in their model the movement of the plates can suddenly start and stop depending on how internally hot a planet is.
