Answer;
B. United States and Russia
Explanation;
-Coal reserves refer to large deposits of coal which, based on geological surveys and engineering studies, are thought to exist to a very high degree of certainty.
-Coal is the most widespread and most abundant fossil fuels. Since so much coal exists, this means that the Earth has significant coal reserves. These reserves are spread all over the globe and mined in every continent except Antarctica. Although the reserves are spread widely, some countries have much more coal than others.
-The United States has more than one-fourth of the worlds known coal reserves, while other major reserves are located in Russia, China, Australia, and India. Most of the worlds coal is buried deep underground and is extracted with traditional mining methods.
The United States and Russia are the two countries that have nearly 50% of global coal reserves. The United States owns 477 billion tons of palpable reserves whereas Russia owns 263 billion tons of coal reserves.
EXPLANATION:
Coal reserves mean the large sediments of coal which are believed to occur to a very high degree of sureness based on geological and engineering studies. Along with the knowledge of their presence, these reserves are also reachable and coal can be created from them cost-effectively.
Coal is the most extensive and most lavish fossil fuels. Since there are many coals exist, it means that the Earth has hefty coal reserves. These reserves are broadened all over the world and excavated in every continent but Antarctica. Although the reserves are broadened extensively, many countries have more coal than others. The explanations of the coal reserves in the United States and Russia are described below:
• The United States owns more than one-fourth of the world's recognized coal reserves, while other major reserves are situated in Russia, Australia, China, and India. Many of the world's coal is deeply buried underground and is mined with traditional mining methods. Where this coal is nearby to the surface, strip mining is employed to uncover coal seams.
Deep mining is expended for deeper buried coal seams. There are over 90% of coal is used for electricity generation in the United States and their coal reserves have an R/P ratio of above 200 years. Most of the coal in the west here is strip-mined, while more than half comes from deep mines in the east.
• Russia also generates and exports a large amount of coal, although these values have drastically fallen as the effect of natural gas just like an alternative fuel. Even though Russia owns 19% of the world's coal reserves and an R/P ratio of above 500 years, many reserves are placed in remote areas of Serbia, which makes transport and production pricey.
