Petroleum and Coal are formed from fossilized trees in swampland, so it means that at some point in history, likely 300 million years ago since most of the world's coal is from that time period, Antarctica had a large swamp and forest. This supports plate tectonics, which indicate that prior to 50 million years ago, Antarctica was usually close to or on the Equator.
coal is a mineral found in the earth where as a volcano is a large 'tunnel like' land mass leading deep within the earth it is similar to a pipe but for lava.
probably quite deep :)

intrusive igneous
A surprising amount of water is found deep inside the earth. Some artesian wells are between 3,000 and 5,000 feet below the surface.
yes
because coal is deep inside the earth
as coal is made of pplant remains that have been buried long ago,it is so deep inside earth.
By mining deep inside the earth. simple!!

Yes. You can consider diamonds 'natural resources' much the same as trees in the forest or coal in the veins of geography. They are formed deep below the earth's surface and erupt to be found by humans via volcanic pipes.
probably quite deep :)
Surface mining can be used when the coal is buried less than 200 feet underground. ... is buried deep within the earth. Some underground ... mine shafts to run machines that dig out the coal. ... In one place, coal is crushed, mixed with water, ... industries use coal, too. Paper, brick, limestone, and
deep mining is how coal removed
deep mining is how coal removed
we dont say a fix depth of underground mine becoz that is depends on geological conditions of the area where we mined and also depends the property of mineral which have to be mined. Companies engaged in this industry extract coal that lies 200 to 1,000 feet below the earth's surface, though some mines are as deep as 2,000 feet.
