Transition (linguistics) A transition or linking word is a word or phrase that shows the relationship between paragraphs or sections of a text or speech. [1] Transitions provide greater cohesion by making it more explicit or signaling how ideas relate to one another. [1] Transitions are, in fact, "bridges" that "carry a reader from section to ...
A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group. [ 1] This is especially important where the descendant group is sharply differentiated by gross anatomy and mode of living from the ancestral group. These fossils serve as a reminder that ...
In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma.
An ecotone is a transition area between two biological communities, [ 1] where two communities meet and integrate. [ 2] It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems ). [ 3] An ecotone may appear on the ground as a gradual blending of the ...
For example, the cutting of the hair for a person who has just joined the army. He or she is "cutting away" the former self: the civilian. The transition (liminal) phase is the period between stages, during which one has left one place or state but has not yet entered or joined the next.

The English language underwent distinct variations and developments following the Old English period. Scholarly opinion varies, but the University of Valencia states the period when Middle ...
v. t. e. In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be ...
The major transitions generally involve the formation of new levels of units of selection, consisting of ensembles of pre-existing entities. Therefore, the evolution of the major transitions can also be seen as the framework for studying the evolution of the levels of complexity in biology. [ 9]
