compositionModels of the internal structure of the Moon and Galilean satellites of Jupiter—Io, Europa, and Ganymede—based on the geophysical (the mass and moment of inertia from recent Lunar Prospector and Galileo gravity measurements, and seismic velocities for the Moon), geochemical (the ...
Earth's Core is thought to be composed mainly of an iron and nickel alloy. This composition is assumed based upon calculations of its density and upon the fact that many meteorites (which are thought to be portions of the interior of a planetary body) are iron-nickel alloys. The core is...
Earth’s Internal Structure The Earth is made up of a variety of materials. However, it is arranged into layers. The solid materials of the Earth are separated into layers according to composition and mechanical properties. Earth’s Internal Structure Earth can be divided into 3 main composition...

Internal Structure of the MoonThe moon has an internal structure similar to Earth's with crust, mantle and core.Republished from a January, 2011 press release by NASA.Moon's Internal Structure: An artist's rendering of the lunar core as identified in findings by a NASA-led research team. ...
But scientists are gaining a fuller understanding of Eris and its differences with Pluto thanks to research that discerns details about this frigid remote world's internal structure and composition based on its orbital relationship with its moon Dysnomia. Eris, the researchers said on ...
and occur at the edge of the Pacific large low-shear-velocity province. Geodynamic modelling demonstrates that these features are consistent with the presence of compositional heterogeneities within the ultralow-velocity zones that may be caused by the remnants of Earth’s early differentiation. We ...
Researchers from the University of Copenhagen have found that some zircons hold information about Mars’ deep interior. This provides insights into the planet’s inner structure. They made this discovery by studying the age and hafnium isotope composition of these crystals. ...
Earth Structure - Layers of Different Strengths The earth is layered with respect to physical properties. The crust and the upper part of the mantle is called the LITHOSPHERE and it is RIGID, BRITTLE and behaves ELASTICALLY. The part of the mantle directly below the lithosphere is termed the...
Uranus's complex internal structure★ 来自 科研支点 喜欢 0 阅读量: 1 作者:BA Neuenschwander,S Müller,R Helled 摘要: Context. Uranus's bulk composition remains unknown. Although there are clear indications that Uranus's interior is not fully convec-tive, and therefore has a non-adiabatic ...
