The Daily Galaxy: Earth’s Hidden Ocean of Fire: The Untold Story Shaping Our Planet’s Core…
New simulations reveal a hidden “ocean of fire” that once existed above Earth’s core, influencing the planet’s internal landscape. These ancient molten seas, known as the basal magma ocean, were a product of Earth’s chaotic beginnings, and they continue to impact the planet’s underground dynamics today... #earthscience #geography #platetectonics
Hired as technician "she had a hard time convincing [her superior, PhD student] Heezen, who initially dismissed her ideas as "old wives’ tale". In fact, it took #Tharp a whole year to persuade her male colleague that she was right, by showing the correlation between her #bathymetricMaps and that of earthquakes in the Atlantic"
"Being a #woman, she wasn't at that time allowed to embark on oceanographic vessels, or earn a PhD"

... a thought experiment, let's reduce the geographical reach for a moment, b/c "thinking globally" never solves any real-world problems:
The American north east, the area b/W #CAN and #DK (#Greenland.)
I have no idea about water depths and #PlateTectonics in that region, but wouldn't a #WaterPipeline be feasible?
#CAN will need increasing amounts of water for #ForestFire fighting, and more and more...

"The only way we could chart the seafloor was by throwing heavy things downward. Everything that lay beneath a few miles of water might as well have been on the moon."

Earth's internal heat budget (Earth 
)
Earth's internal heat budget is fundamental to the thermal history of the Earth. The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantl...

"What did Earth look like a billion years ago? Before Pangea, before dinosaurs—even before oxygen filled the air—continents were on the move. In this Howtown episode, we travel billions of years into the past to explore a groundbreaking new plate tectonic model. Discover how scientists trace ancient continents using zircon crystals, magnetic minerals, glacial scars, and more. From massive dike swarms to lost supercontinents like Rodinia and Nuna, we unravel the clues that reveal Earth's epic tectonic story.
Featuring: Paleomagnetism, zircon dating, cratons, and the surprising history of plate tectonics
NASA satellites, moon rocks, and ancient Canadian crust
With special guest Joe Hanson.

In 1929, Motonori Matuyama showed evidence that the earth’s magnetic field had reversed polarity in the distant past. Scientists say that we might be on the verge of another reversal. #Poetry #Science #History #PlateTectonics #MagneticField #Matuyama (https://sharpgiving.com/thebookofscience/items/p1929a.html)

Volcanic belt (Volcanology 
)
A volcanic belt is a large volcanically active region. Other terms are used for smaller areas of activity, such as volcanic fields or volcanic systems. Volcanic belts are found above zones of unusually high temperature ) where magma is created by partial melting of solid material in the Earth's crust and upper mantle. These areas usually form along tectonic pl...
My Plate Tectonics Android app is now available to anyone who is willing to take part in initial closed testing and has an Android phone. To get it onto Google Play Store apparently I need at least 12 participants. Instructions to take part:
1. Click on this link to join the Google Group which I had to set up for this process:
https://groups.google.com/g/fineartofscienceapps
2. Click:
https://play.google.com/apps/testing/com.companyname.tectonicplatesmaui
If this system works you should then be able to try out the app and leave feedback.
