Geology is the study of the earth, its constituents, the structure of its materials, and the processes that operate on it. An important part of geology is the study of how the earth's materials, structures, processes, and organisms change over time. Geologists study earth processes: Many processes, such as landslides, earthquakes, floods, and volcanic eruptions, can be dangerous to humans. Geologists try to better understand these processes to prevent the construction of important structures where they may be damaged. Geologists can map areas that have been flooded in the past, and they can map areas that may be affected by floods in the future. These maps can be used to guide the development of communities and determine the location of flood protection or flood insurance. Geologists study the earth's materials: People use earth materials every day. They use oil from wells, metals from mines, and water from streams or underground. Geologists conduct studies that identify rocks containing important metals, identify the minerals that produce them, and plan the methods used to extract metals from the rocks. They do similar things to find and produce oil, natural gas and groundwater. Geologists are those who study how the earth was formed, the features, the events that have taken place since the earth was created, the structure, the composition of rocks and minerals, and its history.
