Mining
Some mining is done by scraping away the soil (dirt) from the top of the ground.  This is called surface mining.  Some mining is done by going deep underground into a mine shaft. This is called underground mining.  Some mining, such as gold mining, is done in other ways.  Gold can be mined by searching in the bed of a river or other stream of water to remove the flakes of gold.  This is called panning or placer mining.
