The Physics of Fire
"On average, about 8 million acres of land burns each year from wildfires. Big fires can reduce forests and grasslands to ash and can destroy homes and lives. Sadly, up to 90 percent of wildland fires in the United States are caused by humans’ carelessness, like unattended campfires, burning trash or waste, tossed-out cigarettes, and arson. The remaining 10 percent are usually started by lightning. Controlling and fighting fires isn’t easy. But knowing the science behind a burning blaze helps firefighters tackle the heat and flames to help save property, land and lives. Did you know wildfires often want to move uphill? It’s all part of the physics of how fires start and spread."
