Question

key concepts
mining companies seek and gather valuable resources such as metals, nonmetallic minerals, and fuel sources.
mining companies have developed many techniques to access resources close to the surface of earth, deep underground, and even underwater.
after mining, ores and other extracted materials are processed to separate the desired materials, combine them with other materials, or alter their properties.

(table with columns term, definition, how i remember. rows: ore (empty definition and how i remember), strip mining (definition: a method of mining in which layers of surface soil and rock are removed from large areas to expose the resource; how i remember: when you strip something off, you pull away layers, just as strip mining pulls away layers of soil and rock), subsurface mining (empty definition and how i remember), open pit mining (empty definition and how i remember), mountaintop removal (empty definition and how i remember). another table row with term, definition, how i remember columns at the bottom.)

Explanation:

Answer:

Ore: A naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.
Subsurface mining: The extraction of minerals and ores from underground by digging shafts and tunnels deep into the earth.
Open pit mining: A surface mining technique that involves digging a large, deep hole in the ground to remove ore deposits near the surface.
Mountaintop removal: A form of surface mining where the summits or summit ridges of mountains are removed using explosives to expose coal seams.
