Start studying Earth Differentiation. Cell Differentiation Definition. The geological process by which the Earth came to have its present interiorstructure is called differentiation, and is illustrated in thefollowing figure. See more. The Moon's density is substantially less than that of Earth, due to its lack of a large iron core. The process of cell differentiation allows multi-cellular organisms to create uniquely functional cell types and body plans. It led to the formation of a core, a crust, and eventually continents. The earliest thin crust was probably unstable and so foundered and collapsed to depth. Definition The Earth’s differentiation describes its formation into layers, which include its iron-rich solid inner core, its molten outer core, its solid mantle and its crust on which we live. Cellular differentiation, or simply cell differentiation, is the process through which a cell undergoes changes in gene expression to become a more specific type of cell. Differentiate definition, to form or mark differently from other such things; distinguish. Such a process tends to create a core, crust, and mantle. The assessment of genetic differentiation is based on how the spatial distribution and relative frequencies of alleles at polymorphic loci differ between populations. Cell Differentiation Definition. Define differentiation. How areas of the earth's surface differ; a study of the way human and physical phenomena vary over the earth's surface.

The differentiation, or organization, of the Earth into layers is perhaps the most significant event in its history. (2007) Science 318:1907–1910].
n. 1. a. A variety of techniques have been employed for this purpose, including analysis of allozymes, mitochondrial DNA, randomly amplified polymorphic DNA, and microsatellite loci (Bilton et al. Differentiation. For example, outgassing of a fraction of volatile substances that had been trapped in small amounts within the accreting planet probably formed the earliest atmosphere.
1. As an approach to geography, areal differentiation has come in and out of favour (R. Hartshorn1939; D. Cosgrove1998; D. Massey2005). The Moon's density is substantially less than that of Earth, due to its lack of a large iron core. 2001).
