co2 and Plate Tectonics

At https://cosmosmagazine.com/geoscience/plate-tectonics-the-hidden-key-to-... ... Cosmos is an Australian mainstream science magazine which often has interesting articles on a variety of subjects. In this one it provides an overview of the Plate Tectonics theory - which is worth digesting. It begins with a quote from Carl Sagan, well known to people of a certain generation (the 1960s). Earth lies in the Goldilocks zone - that allows water to exist in a liquid form and the supposition form this is that water allows life to thrive.

Australia Shelf

At https://phys.org/print432201867.html ... the Southern Surveyor research vessal has been looking at the continental shelf system off New South Wales and they have discovered huge underwater landslides close to the shore. They date back hundreds of thousands of years ago (not sure how they arrived at the dates) but presumably earthquake activity was to blame.

    

Hummadruz

The hum has been a subject in Northern Earth magazine for several years - see for example page 25 issue 151, December 2017. At https://phys.org/print431859742.html ... it seems earthquakes can cause the Earth to vibrate for an extended time but in 1998 researchers found the Earth itself generates a low frequency vibrational signal even in the absence of earthquake activity. This has now been extended to the sea floor. Seismometers on land and under the sea have determined the ocean bottom naturally vibrates - a low hum like a wind turbine.

Loch Ness Monster

At https://phys.org/print431945566.html ... geomythology is back in the news. It is still an embryonic science we are told - and has to overcome prejudice and incredulity. It begins with a view over Mount Mazuna, a volcano in Oregon. Native Americans folk tales of its eruption go back 7000 years. Geologists Luigi Piccardi has suggested the Loch Ness monster has something to do with the unusual agitation of the lake's surface water during an earthquake.

Mid Continent Rift

At https://phys.org/print431943147.html ... geologists disprove theory about what stopped the formation of the Mid Continent Rift (in N America). This rift is generally thought responsible for the dramatic cliffs running along the shore of Lake Superior (where ice melt has scoured away sedimentary layers that once covered it ...

Plankton Bloomery

Donald Patten

William suggested looking at the book below after he had read the post at www.sis-group.org.uk/news/plate-tectonics-different.htm ... The book is by Donald Wesley Patten, 'The Biblical Flood and the Ice Epoch' (Seattle 1966) and in particular chapter V, 'Orogenesis: the Cause of Mountain Uplift' which proposed that a passing cosmic body was capable of causing the landscape of the Earth to rise up. In the news post we learnt that the central Anatolian plateau is detached from its roots in the lithosphere.

Plate Tectonics but different

At https://phys.org/print431099162.html ... geophysicists discover evidence for an alternative style of plate tectonics - although it doesn't really sound much like plate movements. J Tuzo Wilson made his reputation in the 1960s by introducing the geology world to the concept of plate tectonics - which is not so long ago. Since then the theory has never been seriously challenged - although heretics still exist.

Kaolin

Scientists claim to have created conditions similar to a so called subduction zone. The transport and release of water during subduction processes is thought to cause volcanic - see article in Nature Geoscience (November 2017) and go to https://phys.org/print430401008.html ... As a continental plate slides beneath oceanic crust (or vice versa) it moves into the Mantle - including various minerals and sediments from the ocean bottom. Over time these transform into different compounds but during the process sea water is released from the oceanic crust - inside the Mantle.

Expanding Earth - for and against

At www.xearththeory.com/expanding-earth-theory-debunked/  ... and www.xearththeory.com/ we have two sides of the argument - with links to papers debunking the idea, and opposite, links to papers enthusiastic of the concept. www.thunderbolts.info ... also had a tpod presentation on the expanding earth idea. However, it might be worth considering why plate tectonics does not exist on other planets (as visited by spacecraft recently). Why only the earth? Might it be that earth is occupied by humans and they are highly inventive.
