Briefly describe how physical geology and historical geology are different

Physical geology is the branch of geology that is concerned with what is happening on Earth in the here and now. Physical geologists study rock and mineral formation, active erosion, volcanic eruptions, and earthquakes. They also look at land use and pollution issues and assist in the search for natural resources like oil and natural gas.

Physical geologists can work in a variety of capacities, ranging from environmental monitoring to agricultural soil analysis to water resources management.

Exploratory geologists who are on the hunt for fossil fuels often find it difficult to do their job if they don't completely understand the past history of the area they are working in, in terms of its geology. Historical geology is the branch of geology that looks at preserved evidence of geological events that occurred in the past. Historical geologists may use their knowledge to reconstruct past landforms such as Pangea, a 'supercontinent' that existed during the Paleozoic and Mesozoic eras. These researchers might also look for evidence of past flooding in an area.(Hope it helps <3)
