Tell me what's the difference between ‘soft' rock and ‘hard' rock geology?

Submitted by: Muhammad
‘Hard' rock geology focuses mainly on igneous and metamorphic rocks. Hard rock geologists work mostly with mineral deposits, mine development and bedrock mapping. Soft rock geology deals with sedimentary rocks where ‘sediment' was formed through long exposure to the elements or glaciers. Soft rock geologists quite often work in the petroleum industry.
