When looking for non renewable resources to extract, geologists look for (3)....
location, lustre and fragmentation of the resource
depth, quality and loose pieces of the resource
location, spatial extent and quality of the resource
core samples, vegetation and amount of the resource
The 3 categories of techniques used to identify the location, spatial extent of the deposit and quality of the resource are..
literature records/historic records, remote sensing techniques, direct sampling geophysical techniques
existing mining, remote sensing techniques, direct sampling geophysical techniques

The 3 remote sensing techniques include:
satellite and aerial imaging, hyperspectral imaging, and radioactive testing
satellite and aerial imaging, magnetic and radioactive testing
satellite and aerial imaging, radiometric imaging, and geophysical datasets for magnetic, gravitational and radioactive testing
satellite and aerial imaging, hyperspectral imaging, and geophysical datasets for magnetic, gravitational and radioactive testing
A potential mine discovery site engages a contractor to fly above their site and take photos. This is an example of: satellite and aerial imaging
wasted money

magnetic, gravitational and radioactive
Remote sensing techniques are those.. (select the MOST correct)
undertaken without actually touching the object
that are often done from a satellite
that are often done from a plane
can use the earth's magnetic field
Usually used with petroleum exploration as ore bodies are too small to produce much of an effect. Relies on dense masses modifying the gravitational field.
electromagnetic surveys
gravitational testing
magnetic testing
seismic surveys
Geophysical techniques measure the variations in the physical properties of rocks such as..
density, magnetism, electrical conductivity, radioactivity
positive charge, negative charge, electrical conductivity
electrical conductivity, elemental composition
density, magnetism, electrical conductivity, chemical reactivity
These surveys are good for detecting metals eg iron ores and rely on rocks being magnetised thus changing the magnetic field
