Scientists have discovered that the acceleration of seismic waves at the Earth's core-mantle boundary is caused by the alignment of post-perovskite crystals due to convective motions deep within the mantle, providing new insights into Earth's interior dynamics.
Scientists have discovered that the acceleration of seismic waves in Earth's D'' layer is caused by the alignment of post-perovskite crystals, which is driven by mantle convection, providing new insights into Earth's inner dynamics.
Scientists have experimentally confirmed that solid rock in the Earth's D'' layer flows due to convection, with crystal alignment affecting seismic wave speeds, providing new insights into Earth's deep interior dynamics.
Scientists at ETH Zurich have solved the long-standing mystery of the Earth's D” layer by discovering that solid rock flows slowly inside the mantle, aligning minerals like post-perovskite, which accelerates seismic waves and confirms mantle convection at extreme depths, revealing dynamic processes deep within Earth.
Scientists at ETH Zurich have confirmed that solid rock flows horizontally deep inside Earth, around 2700-3000 km beneath the surface, solving a 50-year-old mystery about the D” layer by demonstrating that mantle convection occurs in solid rock, not just liquid.
