When two objects, such as sticks, are rubbed together rapidly, the friction between their surfaces increases the temperature. If the temperature becomes high enough, it can ignite small, dry particles (like wood dust or dry leaves), starting a fire. Follow @thatisnewton ,All credits to respective creators/owners.
