Not only does Earth produce neutrinos, it also provides a medium for neutrinos to pass through. This has already led to the discovery of neutrino oscillations, and hence of neutrino masses. Further, Earth affects the oscillations of neutrinos propagating through it, a phenomenon that has been instrumental for precision measurements of neutrino mixing parameters. Future experiments...
Seismology uses energy from earthquakes and other seismic events to provide direct observations of Earth’s interior, and constraints on its physical parameters. Seismic data are sensitive to velocity and attenuation properties, as well as density, anisotropy, and scattering. These measurements are employed in combination with output from geodynamical simulations and mineral physics experiments...
The bulk silicate Earth’s (BSE) composition is the product of planetary accretion, core differentiation, and Moon formation. Given the BSE’s composition one can determine the composition of the bulk Earth and by subtraction calculate the core’s composition. The BSE represents the bulk Earth minus the core, which in today’s terms equals the modern mantle, the continental crust, and the...
