S-290 Intermediate Wildland Fire Behavior 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

True or False: Upward moving air contracts and warms.

True

False

The statement "Upward moving air contracts and warms" is false. In the atmosphere, when air rises, it typically expands due to lower pressure at higher altitudes. As the air expands, it cools rather than warms. This cooling occurs because the molecules in the expanding air spread out and lose energy, resulting in a decrease in temperature. The relationship between air movement and temperature change is essential in understanding fire behavior, especially in wildland fire dynamics, as rising warm air, or convection, plays a significant role in the development of fire.

The cooling of upward moving air also influences the formation of clouds and weather patterns. Hence, understanding the physical behavior of moving air is vital for interpreting fire behavior in wildland management.
