Discontinuities of earths interior
WebStudents examine seismic evidence to determine that the Earth must have a layered internal structure and to estimate the size of Earth's core. Using an inquiry approach, students are divided into two teams (theoreticians and seismologists) to test the simplest hypothesis for what is inside of Earth; that the Earth is homogeneous throughout.

WebUpper Mantle Discontinuities. Cutaway of the Earth’s interior. The abundance of seismic data from numerous seismometers around the globe allows us to investigate detailed structure of the interior. A key seismic … WebThese discontinuities are comparatively weak, however, and the related seismic data are often somewhat controversial due, primarily, to the lateral heterogeneity of the Earth's interior. In general, the mantle discontinuities present a fascinating and challenging subject in seismology.
WebDiscontinuities: A 3D Fourth-Order Staggered-Grid Finite-Difference Modeling by Jozef Kristek and Peter Moczo Abstract We address the basic theoretical and algorithmic aspects of memory-efficient implementation of realistic attenuation in the staggered-gridfinite-difference modeling of seismic-wave propagation in media with material ... WebOur research brings together results from both new and established seismic techniques, providing an integrated and detailed image of discontinuity structure beneath well …
WebThe internal structure of Earth is the solid portion of the Earth, [clarification needed] excluding its atmosphere and hydrosphere. The structure consists of an outer silicate … Earth’s crust is divided in upper and lower layers. What separates these layers is Conrad discontinuity. Upper crust is mostly composed of granite (SIAL), while lower crust is mostly made of basalt (SIMA). Conrad discontinuity is only found on continents. SIMA layer, or oceanic crust, also are in the deep sea. See more Mohorovičić discontinuity or Moho is between crust and upper mantle. How Moho was discovered? An earthquake produces seismic waves, are vibratory movements of rock particles which spread through surface and … See more Divides mantle in upper and lower, it is approximately between 660 and 700 km deep. Passing through this discontinuity, seismic waves increase it’s speed. As explained in post about tectonic plates, lower mantle … See more It is at 5150 km deep, separates external and internal core. P-waves increase speed in internal core region, suggesting it is solid. See more It is between mantle and external core at 2900 km deep, was discovered in 1914. S-waves can’t pass through core because it is liquid. P-waves don’t appear in shadow zone (between 105º … See more
