Sizes and levels of competition

Competition may also exist at dissimilar sizes; some competitions may be between two members of a species, while other competitions can involve entire species. In an example in economics, a competition between two local stores would be measured small compared to competition between several mega-giants. As a result, the consequences of the competition would also vary- the larger the competition, the larger the effect. In addition, the level of competition can also vary. At some levels, competition can be relaxed and be more for pride or fun. However, other competitions can be extreme and bitter; for example, some human wars have erupted because of the intense competition between two nations or nationalities.

A marriage is a relationship between or among individuals, usually recognized by civil authority and/or bound by the religious beliefs of the participants. The fact that marriage often has the dual nature of a binding legal contract plus a moral promise, can make it difficult to characterize.In one form or another, marriage is found in virtually every society. The very oldest records that refer to it speak of it as an established custom. Despite attempts by anthropologists to trace its origin , evidence is lacking.

In Western societies, marriage has traditionally been understood as a monogamous union, while in other parts of the world polygamy has been a common form of marriage. Usually this has taken the form of polygyny but a very few societies have permitted polyandry . Precise definitions vary historically and between and within cultures: modern understanding emphasizes the legitimacy of sexual relations in marriage, yet the universal and unique attribute of marriage is the creation of affinal ties . Traditionally, societies encourage one to marry "out" far enough to strengthen the ties, but "close" enough so that the in-laws are "one of us" or "our kind".

Sinkholes, also known as sinks, shakeholes or dolina, and cenotes, are formed by the collapse of cave roofs and are a feature of landscapes that are based on limestone bedrock. The result is a depression in the surface topography. This may range anywhere from a small, gentle earth-lined depression, to a large, cliff-lined chasm. Most often there is a small area of rock exposure near or at the bottom of a sinkhole, and a patent opening into the cave below may or may not be visible. In the case of exceptionally large sinkholes, such as Cedar Sink at Mammoth Cave National Park, there may actually be a stream or river flowing into the bottom of the sink from one side and out the other side.

Sinkholes often form in low areas where they form drainage outlets for a closed local surface drainage basin. They may also form in currently high and dry locations. Florida has been known for having frequent sinkholes, especially in the central part of the state.
