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 ...
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 (*).
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
In geology, a subaerial unconformity is a surface that displays signs of erosion by processes that commonly occur on the surface. [1] These processes generating the subaerial unconformity can include wind degradation, pedogenesis, dissolution processes such as karstification as well as fluvial processes such as fluvial erosion, bypass and river rejuvenation.
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);
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 ...
A word, phrase, clause, or utterance may be grammatically well-formed, meaning it obeys the rules of morphology and syntax. A semantically well-formed utterance or sentence is one that is meaningful. Grammatical well-formedness and semantic well-formedness do not always coincide.
