Fire

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.

Fire is hot because conversion of the weak double bond in molecular oxygen, O₂, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O₂); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.

Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes. The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover.

Combat

Combat or fighting is a purposeful violent conflict meant to weaken, establish dominance over, or kill the opposition, or to drive the opposition away from a location where it is not wanted or needed.

The term combat (French for fight) typically refers to armed conflict between opposing military forces in warfare, whereas the more general term "fighting" can refer to any physical or verbal conflict between individuals or nations. Combat violence can be unilateral, whereas fighting implies at least a defensive reaction. A large-scale fight is known as a battle. A verbal fight is commonly known as an argument.

Background

Combat may take place under a specific set of rules or be unregulated. Examples of rules include the Geneva Conventions (covering the treatment of people in war), medieval chivalry, the Marquess of Queensberry rules (covering boxing) and several forms of combat sports.

Combat in warfare involves two or more opposing military organizations, usually fighting for nations at war (although guerrilla warfare and suppression of insurgencies can fall outside this definition). Warfare falls under the laws of war, which govern its purposes and conduct, and protect the rights of combatants and non-combatants.

Mexico City

Mexico City (Spanish: Ciudad de México  audio  American Spanish: [sjuˈða(ð) ðe ˈméxiko]; abbreviated as "CDMX") is the capital of Mexico. Mexico City is the country's largest city as well as its most important political, cultural, educational and financial center.

As an "alpha" global city Mexico City is one of the most important financial centers in the Americas. It is located in the Valley of Mexico (Valle de México), a large valley in the high plateaus at the center of Mexico, at an altitude of 2,240 metres (7,350 ft). The city consists of sixteen municipalities (previously called boroughs).

The 2009 estimated population for the city proper was around 8.84 million people, with a land area of 1,485 square kilometres (573 sq mi). According to the most recent definition agreed upon by the federal and state governments, the Greater Mexico City population is 21.2 million people, making it the largest metropolitan area in the western hemisphere, the eleventh-largest agglomeration, and the largest Spanish-speaking city in the world.
