Differentiation
The Earth did not have the interior structure described in the preceding section when it was formed.
differentiation Variation with depth in the density and composition of a body, such as Earth, with low-density material on the surface and higher density material in the core.
DIFFERENTIATION - Process by which an originally homogeneous planetary or asteroidal body separated into regions of different composition, such as core, mantle and crust.
Differentiation: Chemical zonation caused by differences in the densities of minerals; heavy materials sink, less dense materials float.
Differentiation
The separation of planetary material according to density.

Differentiation - The gravitational separation of the interior of a planet into layers according to density. When differentiation occurs inside a molten body, the heavier materials sink to the center and the light materials rise to the surface ...
Differentiation
In planets, a process whereby the primordial substances are separated, the heavier elements sinking to the center and the lighter ones rising to the surface.

Differentiation
The separation of heavy matter from light matter, thus causing a variation in density and composition.
differentiation - (n.)
The sinking of relatively heavy elements into the core of a planet or other body. Differentiation can occur only in fluid bodies, so any planet that has undergone this process must once have been at least partially molten.
The differentiation of objects into separate categories called "highly variable" versus "transient" is somewhat artificial and not always clear cut, although in general, ...
The differentiation among the jovians is also understood in this model.

The monochromaticity and brilliance of the laser light enables the differentiation between interfering beams of hundreds of meters, in contrast to a maximum of 20 centimeters for the classical interferometers.
differentiated when the interior of a large object has undergone differentiation so that denser material lies closer to the object's core.
The asteroids from which these meteorites were fragmented, though probably formed from a relatively cool solar nebula, experienced internal heating, core formation, and igneous differentiation within a few million years of the formation of the solar ...
But in some regions, there is not much differentiation between the seasons. Since different constellations are visible at different times of the year, you can use them to tell what month it is.
The crust, showing pronounced chemical differentiation, formed early. Subsequent impact of very large meteorites depressed the mare basins, at the same time thrusting up the surrounding crust to form the highlands.
What mechanism(s) are responsible for the differentiation of the asteroids into metallic and rocky types?
Why are there more Trojan asteroids in Jupiter's L4 point than its L5 point?

Surface evolution was characterized by differentiation, cratering, flooding, and surface erosion and uplift. The volatile elements H, He, C, and N are extremely depleted in the Earth.
This caused the differentiation into crust, mantle, and core, with the lighter silicates moving up and outward to form the mantle and crust and the heavier elements, mainly iron and nickel, ...
Each planet has a layered structure that developed through a process called differentiation.
The younger regions might have been produced by incomplete differentiation of the moon, a process in which upwelling of lighter material surfaced in limited areas.

Therefore, by ensuring the planting took place at the correct time the risk of a failed harvest was kept to a minimum, particularly in regions where the differentiation between the seasons was slight.
This is used to invert the rotation curve v(r) and thus by differentiation or modelling to obtain the mass distributions M(r), r (r) in disk galaxies.

that Titan's interior is rather mixed up, unlike the Earth for example, which has differentiated into distinct layers comprising a core, mantle and crust. In contrast, Titan's interior probably never heated up enough to cause differentiation - only ...
This melting may well have had an important role in the early differentiation of the Earth, in particular producing the earliest evolved crust which would then be available for recycling by nascent plate tectonic processes.
Later advances were the organization of chromosomes, DNA, and nuclei for passing on characteristics, greatly expanding the powers of natural selection through adaptation. When multicellular life brought the differentiation of body parts, ...
Putting a, b, c, d, for the constants, the general form of the solution will be x = fl (a,b,c,d,t) y = f2(a,b,c,d,t) From these may be derived by differentiation as to t the velocities dt =f '1(a,b,c,d,t) = x' ?
Mathematically, coriolis acceleration comes from the differentiation of terms containing the angular velocity in the expression for the absolute velocity of the particle.
