Answer:
Super position
Faunal Succession
Crosscutting Relationships
Inclusions
Explanation:
Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it. This law follows two basic assumptions: (1) the beds were originally deposited near horizontal, and (2) the beds were not overturned after their deposition.
Faunal Succession: Similar to the law of superposition is the law of faunal succession, which states that groups of fossil animals and plants occur throughout the geologic record in a distinct and identifiable order. Following this law, sedimentary rocks can be “dated” by their characteristic fossil content. Particularly useful are index fossils, geographically widespread fossils that evolved rapidly through time.
Crosscutting Relationships: Relative ages of rocks and events may also be determined using the law of crosscutting relationships, which states that geologic features such as igneous intrusions or faults are younger than the units they cut across.
Inclusions: Inclusions, which are fragments of older rock within a younger igneous rock or coarse-grained sedimentary rock, also facilitate relative dating. Inclusions are useful at contacts with igneous rock bodies where magma moving upward through the crust has dislodged and engulfed pieces of the older surrounding rock.
Answer:
Elections are a process by which a population elects one or more of its representatives to represent it in an institution. Elections are the most democratic means of representing and forming representative bodies at all levels of social grouping. There is usually talk of local and national elections. Elections are held at regular intervals, which are predetermined.
National and local elections are held in accordance with the applicable electoral law of each state and which is an organic law that cannot be repealed without being replaced by another newer one. The electoral law determines the manner, procedure and division of the country into constituencies. It can generally have either a majority or a proportional effect on the distribution of seats.
Answer:
Denver
Explanation:
Denver, Colorado, is the city from the list that has the least chances to have a tropical wet/dry climate. This city actually has summers that are considered as mild, with the temperatures being in the the lower 30's C degrees, while the night temperatures drop to twice less than the daily temperatures. The winters on the other hand, are cold and snowy, which is not a trait of the tropical climates, but instead of the continental climate types, with the temperatures regularly being bellow the freezing point throughout the winter months.
