Which statement best describes an environmental consequence of unsealed landfills? Landfills can produce carbon dioxide that lea
k into the atmosphere. Long-term exposure to mercury and lead in landfills can cause cancers.
Heavy metals are released as leach ate into surrounding waterways.
Materials in landfills undergo decomposition for hundreds of years.
The correct statement describing environmental consequence of unsealed Landfills is : ( A ) Landfills can produce carbon dioxide that leak into the atmosphere
A landfill is composed of 4 essential components and some are ;
bottom linear
hydrogeologic component and
A cover ( seal )
Given that a landfill constitutes of about 40 to 60 percentof C0₂ the environmental consequence of not providing a proper seal for the landfill will be the leakage of C0₂ into the atmosphere. while
The release of Heavy metals as leach ate into the surrounding can be controlled with the provision of a system in the landfill, materials in landfill undergo decomposition for a long period of time.
Hence we can conclude that Landfills can produce carbon dioxide that leak into the atmosphere.
If you go on mc3.edu/admissions/applying-to-mccc/testing-and-assessment/assets/biology-placement-test.pdf page 11 it will tell you all the answers to your questions....
Mainly to make life easier. if one layer changes than scientists don't need to change all of their data. it also helps keep organized. hope this helped ebs02 :)
