A new hypothesis about the Earth’s internal dynamics suggests that Unbalanced Forces and Torques in the Earth-Moon-Sun System Drive circulation throughout the mantle.
The analysis, led by geophysicist Anne M. Hofmeister of Washington University in St. Louis, is presented by An alternative to the hypothesis that the movement of tectonic plates is related to convection currents in the Earth’s mantle. Convection involves increasing the buoyancy of hot liquids, which Hofmeister and colleagues argue does not hold true for solid rock. They argue that force, not heat, moves large objects. The new research was published in a special article in the newspaper American Geological Society.
The inner workings of the Earth are generally modeled as scattering heat from internal radioactivity and by residual energy created during collisions when our planet formed. But even proponents of mantle convection admit that this amount of internal thermal energy is insufficient to drive large-scale tectonic movement. There are other problems with the use of convection to explain the observed plate motions.
Alternatively, the floor plates can change Because the Sun exerts such strong gravitational force on the Moon that it causes the Moon’s orbit around the Earth to lengthen.
Over time, Hoffmeister said, the position of the parietal center, which is the center of mass between the orbiting bodies of the Earth and the Moon, has moved closer to the Earth’s surface and is now oscillating 600 km per month relative to the Earth’s center. This generates internal tensions, as the Earth continues to spin.
“Because the oscillating Bari center is about 4,600 km away from the geographic center, the Earth’s orbital latitudinal acceleration and solar clouds are unbalanced except at the Alpari center,” Hoffmeister said. It’s a statement. “The planet’s warm, thick, and strong inner layers can withstand these pressures, but the thin, cold, and brittle lithosphere responds by fracturing.”
Daily rotation flattens the Earth from a perfect spherical shape, contributing to this fragile rifting of the lithosphere. The authors suggest that these two independent ancestors create the observed mosaic of panels in the outer shell. The diversity of plate motions comes from changes in the magnitude and direction of unbalanced gravitational forces over time.
But how do you test this alternative? Hofmeister suggested: “One of the tests will be a detailed examination of Pluto’s tectonics, It’s too small and too cold for convection, but it has a giant moon and a surprisingly young surface.”
The study includes a comparison between rocky planets, showing that the presence and longevity of volcanoes and tectonics depends on the particular composition of the size of the moon, the orbital orientation of the moon, the proximity to the sun, and the rates of rotation and cooling of the body.
Hofmeister noted that Earth is the only rocky planet that contains all the factors needed for plate tectonics.
“Our exceptionally large moon and special distance from the sun are essential,” He said.
