Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic.
The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created
“planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
Answer:
The crust is thinner and less dense than the mantle.
Carbon Monoxide has 2 atoms total - one atom of carbon (C) and one atom of oxygen (O) chemical formula is CO
Ethylene has 6 atoms total, 2 atoms of carbon (C) and 4 atoms of hydrogen (H), chemical formula is C2H4.
Ethylene has four more atoms than carbon monoxide (6-2) = 4
