地球內部有些什麼東西壞了嗎？ 科學家s探索為什麼數千年久的進程已停頓下來
Something’s broken inside Earth? Scientists explore why millennia-old process has stalled

Scientists have diagnosed the Earth with a bizarre geological condition known as ‘stagnant slabs’, meaning tectonic rocks subducted into the fiery hot mantle mysteriously become wedged hundreds of miles below the surface.

But researchers from the University of Colorado Boulder believe they have discovered the reason for what appears to be a glitch in the Earth’s internal mechanism.

Using computer simulations of seismic activities under the Pacific Ocean scientists found that slabs of rocky tectonic plates may be temporarily obstructed from falling into seamlessly into the subduction, melting and convection current routine of the Earth’s mantle by a “thin, weak” layer of material.
