An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. In general, the older layer was exposed to erosion for an interval of time before deposition of the younger layer, but the term is used to describe any break in the ...
Insubordination, the act of willfully disobeying an order of one's superior; Dissent, a sentiment or philosophy of non-agreement or opposition to a prevailing idea or entity
Cross-cutting relationships can be used to determine the relative ages of rock strata and other structures. Explanations: A – folded rock strata cut by a thrust fault; B – large intrusion (cutting through A); C – erosional angular unconformity (cutting off A & B) on which rock strata were deposited; D – volcanic dike (cutting through A, B & C); E – even younger rock strata (overlying ...
In an experiment by Cairns et al., preschool children aged 4–6 were presented sentences such as (14) and (15) orally. (To make sure that the meaning of the sentences was clear to the children, sentences were enacted with toys.) While sentence (14) is well-formed in the adult grammar, sentence (15) is not, as indicated by the asterisk (*).
Hutton's Unconformity is a name given to various notable geological sites in Scotland identified by the 18th-century Scottish geologist James Hutton as places where the junction between two types of rock formations can be seen. This geological phenomenon marks the location where rock formations created at different times and by different ...
A major sentence is a regular sentence; it has a subject and a predicate, e.g. "I have a ball." In this sentence, one can change the persons, e.g. "We have a ball." However, a minor sentence is an irregular type of sentence that does not contain a main clause, e.g. "Mary!", "Precisely so.", "Next Tuesday evening after it gets dark."
In elliptical sentences (see below), inversion takes place after so (meaning "also") as well as after the negative neither: so do I, neither does she. Inversion can also be used to form conditional clauses, beginning with should, were (subjunctive), or had, in the following ways: should I win the race (equivalent to if I win the race);
Hutton's Unconformity at Jedburgh. Above: John Clerk of Eldin's 1787 illustration. Below: 2003 photograph. Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, [1] is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the ...
