← GeographyWhich consequence often results when boreal forest permafrost thaws?
A)Methane hydrate destabilization and release✓
B)Increased atmospheric albedo and cooling
C)Rapid silicate weathering by acid rain
D)Formation of extensive dune fields
💡 Explanation
Methane release increases because the breakdown of organic matter due to microbial activity in the thawing permafrost generates methane. This process, known as methanogenesis, therefore destabilizes the hydrates rather than causing other climatological or geochemical effects.
