Ignition Component Ignition Component The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. The ignition component can range from 0 when conditions are cool and damp, to 100 on days when the weather is dry and windy. Theoretically, on a day when the ignition component registers a 60 approximately 60% of all fire brands that come into contact with wildland fuels will require suppression action. Ignition normally takes place in the dead component of the fine fuels. Three distinct steps must be considered in this ignition
Mesoamerican Archaic period differed regionally. Most Archaic sites are not very well preserved or visible, which hampers archaeologists' ability to discover and study Archaic period sites. As a result, not many Archaic sites have been identified, although major sites like Guilá Naquitz and Colha have been explored by archaeologists. Most known Archaic sites are in the Mesoamerican highlands or along the coasts, though there are sites throughout the region. During the Archaic period, Mesoamerican peoples slowly changed from being nomadic hunter-gatherers to semi-sedentary or sedentary foragers and farmers.
