The branch of geology that studies Earth's rocks, minerals, and geological structures using aerial observation, photography, and surveys conducted from aircraft.
From aero- (air) and geology (study of Earth). Developed in the 20th century as aviation technology made systematic aerial geological surveys possible and practical.
Aerogeology revolutionized mining and oil exploration—geologists could now scan hundreds of square miles in a day, spotting rock formations and fault patterns that predicted where valuable resources might be hidden!
