Geological Science is a broad area of study which focuses on a knowledge of the present Earth in order to interpret its history and origin. Geologists study the structure and composition of the Earth in order to locate natural resources, to give warnings of natural disasters, to ensure the placement of buildings on firm foundation, and simply to learn more about our natural environment. Other geologists are involved in preserving and cleaning up the environment.

Field geologists spend most of their time exploring. Other geologists work in laboratories, museums and computer centers analyzing specimens and data. Many geologists work in areas where there are large oil or mineral deposits (Texas, California, Louisiana, Colorado, Oklahoma or overseas). Construction and engineering firms employ geologists to measure the depth of bedrock and predict the stability, strength, and permanency of rock formation.
