What are the three types of surface mines?
The three types of surface mines are open-pit mines, strip mines, and mountaintop removal mines. Open-pit mines involve extracting minerals from a large, open excavation. Strip mines involve removing layers of soil and rock to expose the resource. Mountaintop removal mines involve removing the summit of a mountain to access the coal seams underneath.
What are the types of surface mines?
Strip mining, Open pit mining and Mountaintop removal mining
Where is coal dug?
Coal is primarily dug from underground mines. These mines are typically located in coal-rich regions and are accessed by tunnels and shafts. Surface mining methods, such as strip mining or mountaintop removal, may also be used in areas where the coal seam is close to the surface.
What were the 2 types of the mines before the industial revolution?
Before the Industrial Revolution, the two primary types of mines were surface mines and underground mines. Surface mining involved extracting minerals and ores from the earth's surface, often through open-pit or strip mining methods. In contrast, underground mining required digging tunnels and shafts to reach deeper deposits, which was more labor-intensive and dangerous. These methods laid the groundwork for the more mechanized processes that would emerge during and after the Industrial Revolution.

What provides the greatest surface area upon which a solvent can strip solute particles?
We can identify which solvent can strip solute particles with the greatest surface if we have the option to choose from. This statement is not a definition, it is an analogy question for a given situation.
