Geology is about describing the various types of sediment that makes up our earth. The information is gathered using coring and drilling techniques from geotechnical surveying and often combined with geophysical surveying and seismic techniques to obtain a complete image of not only the type of material but also its distribution. 

Geological surveys perform an important role in construction and engineering and land and water management but also in farming and conservation and mining & energy to determine the correct type of bottom.
