| show | rapid, oxidative, endothermic, and exothermic
🗑
|
||||
| show | reactions: endothermic, exothermic. phases: preignition, ignition, and combustion
🗑
|
||||
| show | biomass is heated to ignition temperature. the goal is to dehydrate the fuel and raise the temperature to ignition. it is endothermic (making things "mushy mushy")
🗑

|
||||
| show | flaming and glowing/smoldering
🗑
|
||||
| flaming combusiton | show 🗑
|
||||
| show | surface oxidation, resulting in incomplete combustion of solid biomass. little to no visible flame, charring
🗑
|
||||
| show | due to water vapor, gases/volatile organic compounds, and carbon particles releasing to form smoke (aka this is what smoke indicates)
🗑
|
||||
| show | convection, radiation, and conduction
🗑
|
||||
| show | results from fast moving hot air moving upwards, carrying smoke and particles influenced by wind.

🗑
|
||||
| show | fuel type, wind speed, steepness of slow, and changes in fire intensity
🗑
|
||||
| show | longer heat exposure can cause soil organism death, change in soil properties (like aggregate structure, moisture content, and increase in Fe and Al oxides), nutrient loss and unavailable complexes of Ca and Mg, and organic matter decomposition
🗑
|
||||
| show | shows the degree of departure from historical conditions and the application of fire as a management tool
🗑
|
||||
| what are characteristics used to describe a fire regime for a given ecosystem type | show 🗑
