Answer:
by developing more efficient methods of mining coal
Explanation:
Coal is a combustible black or brownish black sedimentary rock. Coal is produced by the dead plant matter. It is a fossil fuel that is used for generating electricity in the thermal power plants, used as cooking fuel, and fuel in automobiles. The burning of the coal results in the liberation of carbon dioxide, sulphur dioxide and carbon monoxide gases in the environment. These gases are responsible for causing the air pollution.
Developing more efficient methods of mining coal is not a conservation tactic related to coal consumption because the more the efficient mining will promote the excavation of the coal, which will further contribute to its extensive consumption and air pollution.
the point at which warm air begin to raise before colliding with cold air is 3
(C.) The layers of the Earth are uniform in thickness
This is untrue. The mantle is far large than the crust and there are other large size differences.
A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.The faces of the dodecahedron are pentagons.<span>A dodecahedron is a polyhedron with 12 faces . A dodecahedron is a three-dimensional shape having twelve plane faces. </span>
The correct answer is - the release of methane from thawed permafrost.
In the past decade it has been noticed that the levels of methane are increasing in the atmosphere, and the biggest ''producer'' of this methane is the melting permafrost. There's huge amounts of methane trapped underground bellow the permafrost. But the permafrost is melting because of the global worming, so the methane is free to come out and go up in the atmosphere.
