INTERNAL structure of the EarthGEOMAGNETISMEARTH'S mantleEARTH temperatureHYDROSPHERE (Earth)The presence of a planetary magnetic field is an important ingredient for habitability. The coexistence of a solid and a liquid core can facilitate the maintenance of a compositionally driven dynamo; however, ...
The mission also will answer longstanding questions about Earth's moon and provide scientists a better understanding of the satellite from crust to core, revealing subsurface structures and, indirectly, its thermal history.The Research Team In addition to Weber, the team consisted of scientists from ...
Review Lecture: The Dynamical Properties and Internal Structures of the Earth, the Moon and the Planets The aim of this review is to bring together and relate recent progress in three subjects - the internal structure of the Earth, the behaviour of materials ... AH Cook - 《Proceedings of ...

The internal structures of type I spherules (melted micrometeorites rich in iron) have been investigated using synchrotron‐based computed microtomography. Variations from sphericity are small—the average ratio of the largest to the smallest semimajor axis is 1.07 ± 0.06. The X‐ray tomographs ...
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 conclude that small-scale structures that ...

Journal of Archaeological Science, Volume 46, 2014, pp. 96-106 Show abstract The Chalcolithic site of Marj Rabba, in the lower Galilee of Israel, features shallow limestone structures situated in a terra rossa matrix. Calcareous substrates such as terra rossa, common throughout the region, are...
Another notable example, on a larger scale and of some importance to the general circulation, is tidal mixing in the Indonesian seas. With strongtidal currentsand complex bathymetric structures the Indonesian seas are well known for large internal tides; the region has provided some now-classic exa...
Internal erosion by piping is one of the main causes responsible of accidents and failures of earth structures such as embankment dams and dykes. This phenomenon occurs when concentrated leak develop in pre-existing defects in the earth fill such cracks and micro fissures, discontinuities, hydraulic...
