Geology is the study of the earth. This is a very simple definition for something so complex. Geology involves studying the materials that make up the earth, the features and structures found on Earth as well as the processes that act upon them. Geology also deals with the study of the history of all life that’s ever lived on or is living on the earth now. Studying how life and our planet have changed over time is an important part of geology. An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Joint, in geology, a brittle-fracture surface in rocks along which little or no displacement has occurred. Present in nearly all surface rocks, joints extend in various directions, generally more toward the vertical than to the horizontal. Joints may have smooth. In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur as single isolated folds or in periodic sets (known as fold trains). Synsedimentary folds are those formed during sedimentary deposition. Investigations of the physical properties and internal processes are called geophysics, those that concern chemical processes are geochemistry, and those that deal with ancient biology are paleontology. Geology has powerful tools of its own, primarily geologic mapping, but in large part it draws upon its sister sciences in investigating the origin and history of the earth.
