A geologist is a scientist who specializes in the study of the earth. Geologists analyze the materials that make up the earth, the structure of the earth, and the processes going on under and above the surface of the earth. Geology is also concerned with the history of the earth, how the materials, structures, processes and the organisms have changed over time. It is a field of science that attempts to understand the history of our planet through the examination of the earth’s crust, rocks, minerals, and fossil remains. Geologists need to a strong base in other sciences like physics, chemistry, biology and mathematics also to be able to explain the various phenomena that affect the earth. As compared to other scientists, they are required to spend more time outdoors though laboratory work is also essential to analyze the samples. Geologists try to understand why natural processes like earthquakes, landslides, floods, etc. occur and how man can take precautions to minimize damage from these disasters. They also study and help to locate various types of materials found in earth like petroleum, metals, underground water, etc. which are of use to human beings. Geologists analyze fossil remains of the ancient organisms that once inhabited the earth in order to determine the process of evolution and climate change.
