What Does a Geologist Do?

Geologists work to understand many processes such as landslides, earthquakes, floods and volcanic eruptions. All of this processes can be hazardous to people. If geologists can prepare maps of areas that have flooded in the past they can prepare maps of areas that might be flooded in the future. These maps can be used to guide the development of communities and determine where flood protection or flood insurance is needed. 

We use earth materials every day. We use oil that is produced from wells, metals that are produced from mines, and water that has been drawn from streams or from underground. Geologists conduct studies that locate rocks that contain important metals, plan the mines that produce them and the methods used to remove the metals from the rocks. They do similar work to locate and produce oil, natural gas and ground water. 

Geologists also study of earth history. Nowadays, we are concerned about climate change, whether global warming or global cooling. Many geologists are working to understand about the past climate change and how its change across the time. The historical geology information helps geologist to understand how our current climate is changing.
