Earth's outer core is a fluid layer about 2,260 km (1,400 mi) in height (i.e. distance from the highest point to the lowest point at the edge of the inner core) [36% of the Earth's radius, 15.6% of the volume] and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

The preliminary reference Earth model (PREM) plots the average of Earth's properties by depth. [1] It includes a table of Earth properties, including elastic properties, attenuation, density, pressure, and gravity. PREM has been widely used as the basis for seismic tomography and related global geophysical models. [2]

A diagram of the internal structure of Earth. The lithosphere consists of the crust and upper solid mantle (lithospheric mantle). The green dashed line marks the LAB. The lithosphere–asthenosphere boundary (referred to as the LAB by geophysicists) represents a mechanical difference between layers in Earth's inner structure.
Geological perspective correlation is a theory in geology describing geometrical regularities in the layering of sediments. Seventy percent of the Earth's surface are occupied by sedimentary basins [1] – volumes consisted of sediments accumulated during million years, and alternated by long interruptions in sedimentation (hiatuses).
The layer cake like appearance of concordant strata laid down over hundreds of thousands of years (in northern Spain) Strata turned sideways by orogenic forces near San Sebastián, Spain. The geologic record in stratigraphy, paleontology and other natural sciences refers to the entirety of the layers of rock strata.
For example, The GeoPad project describes the combination of technology, teaching field geology, and geologic mapping in programs such as Bowling Green State University’s geology field camp. At Urbino University (Italy) it:Università di Urbino , Field Digital Mapping Techniques are integrated in Earth and Environmental Sciences courses since ...
