Flexi Says: Certain places on Earth are more likely to have certain ores. Geologists search for the places that might have ore deposits. For example, if you want copper, you need to look at regions with particular geology. Copper is often found where hot fluids came off of a magma intrusion. Aluminum is found in intensely weathered soils in tropical areas. Some of the valuable deposits may be hidden underground. Some may be at the surface.
