Where is methane most likely to be found?

Methane is less dense than air, which means it tends to rise and accumulate in higher areas. However, the most likely scenario for methane accumulation is in low, closed spaces, such as mines, where gases can become trapped due to limited ventilation. In these confined environments, the concentration of methane can increase significantly, posing a serious risk of explosion or asphyxiation. Understanding the behavior of gases in different surroundings is crucial for safety in mining operations, as adequate ventilation is essential to minimize risks associated with methane.

In contrast, well-aerated areas would typically disperse methane quickly, reducing any potential hazard, while ground level and high places do not provide the same risk factors for methane accumulation as closed spaces do.
