About 1,800 miles beneath the surface, Earth's internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the ...

Our planet, Earth, is structurally composed of a series of concentric internal spherical layers that are divided into: crust, upper mantle, mantle, outer core and inner core. Every ...

In the absence of a 6,000 km-deep hole to conduct observations, scientists hoping to learn about the internal structure of the Earth presently have few options but to monitor seismic waves. However, ...

Earth, with its metallic core, semi-fluid mantle and outer crust, has a more clearly defined structure than Ceres. Artist's conception of Ceres’ internal structure, based on data from the Dawn ...
