Question
Explain how landfill sites can release methane from decomposition.
Answer
Landfill sites release methane as organic waste decomposes anaerobically, meaning without oxygen. This process occurs when bacteria break down the waste, producing methane gas as a byproduct, which can escape into the atmosphere.
Explanation
This question tests the understanding of the biological processes occurring in landfills and their environmental impact. It requires students to connect the decomposition of organic matter with methane production, highlighting the role of anaerobic bacteria.
Common mistake
Misunderstanding Methane Release
Students often think that landfill sites only produce carbon dioxide and do not realize that methane is also released during decomposition.
Emphasize that methane is produced as organic waste decomposes anaerobically in landfill sites, highlighting the role of decomposition in methane emissions.
