The branch of science known as geology relates to the study of solid earth. That means that geologists study features of earth that are based on rocks and minerals. Some of the features that they study include mountains, volcanoes, canyons, and plate tectonics. Geologists study these features extensively because they want to investigate the gradual processes that form them and by studying the processes, they can help prevent devastation from future disasters (King, 2018). These processes include natural disasters like earthquakes. Geologists also study the composition of these formations by taking samples and analyzing them. These studies of the earth are collectively called geology.
