New findings suggest a series of current events are weakening the Earth’s magnetic field. Above the liquid outer core is the mantle; a solid rock composition which can be moldable due to the intense heat and high pressure. At the boundary between Earth’s core and mantle at a depth of 2900 km (1,802 miles), there is an intense heat exchange.
One ongoing process is the shifting of tectonic plates – especially at subduction zones such as Sumatra, Cascadia, and Puerto Rico. This sinking of tectonic plates (Earth’s crust) cools the mantle, which in-turn, speeds up the process of “convection”. (the transfer of heat by the circulation or movement). Simultaneously, super-heated liquid rocks from the Earth’s outer core form large bubbles called ‘mantle plumes’, which rise into the lithosphere, then continue further in producing seamounts. (Active seamounts are submarine volcanoes.)
Paradoxically, as the result of a cooling mantle due to tectonic plate influence, submarine and surface volcanoes, (along with other occurrences – coming in Part-II) an accelerated heat flow from the Earth’s hot core increases – until the mantle and outer core compensate to its “ambient” (equalized) temperature.
In a new study presented by geophysicists from Columbia University’s Lamont-Doherty Earth Observatory, the team has identify natural long and short-term cycles indicating an expansion and contraction in the development of seamount rifts. They have discovered a strong correlation to the Moon and Sun’s gravitational tugging. These shifting of cycles also correspond with Earth’s change in spinning dimensions as related to its geosynchronous and elliptical orbits.
