Which statement is true about dry environments compared to moist environments in relation to fire behavior?

Dry environments typically exhibit larger temperature ranges compared to moist environments, primarily due to the reduced capacity of water to moderate temperature. In such conditions, the absence of moisture leads to more significant fluctuations between day and night temperatures. This larger temperature variation can directly affect fire behavior by influencing fuel moisture content and the rate at which combustion occurs.

Higher temperatures can exacerbate the drying of fuels, making them more susceptible to ignition and flame spread. As a result, fire behavior is generally more intense and can spread more rapidly in dryer environments. This contrasts with moist environments, where higher humidity helps to stabilize temperatures and can slow down the drying of fuels, leading to decreased fire intensity and spread.

Understanding the impact of moisture on temperature ranges and fire behavior is crucial for predicting and managing wildfire risks effectively.
