What is geology? Geology is the study of rocks and other surface materials and how they form and evolve over time. It is the scientific study of earth’s surface materials and their relationships to one another. It is a very important subject that has been studied for thousands of years. Geology has many subtopics including paleontology, archeology, and geodesystology.
Geology is the physical description of how the earth’s surface is laid out. Geologists can divide up their research into two broad categories: mineral and tectonic. Within each of these categories there is a division into what is geological and what is physical. Mineral geology is focused on the study of how different minerals form and how they interact with each other. Tectonic geology focuses on the study of earth’s movement and how it affects the surface. These two branches of geology will be discussed in more detail in this article.
Geologists study different types of rock and look for patterns and discontinuities in the rock that tell them about the past and what lies beneath. One type of test that is often done is the survey of landforms. By taking measurements of the elevations and surfaces of rocks and other landforms, geologists can determine what age a particular rock or formation is. They can also determine how solid it is and if it is moving around. This can help them determine if there are any hidden layers beneath the surface that have not yet been revealed. This can give clues as to what the Earth’s interior composition is like.
In addition to looking for evidence of the Earth’s age and movements, geologists must also look for clues about the history of sedimentation. Sedimentary rocks consist of layers of various thicknesses and structures that build up over time. Each layer has the potential to hold varying amounts of organic material, such as fossils and other minerals that made their way into the Earth’s crust. If there are layers that are missing, or if they are too thin to hold anything substantial, then the formation of that particular rock cannot be classified as geologically valid. However, what a scientist may see as normal erosion and migration can actually be evidence of large volcanic eruptions.
Unlike the environment, geology is controlled by the elements. The earth’s climate, magnetic fields, tectonic forces, and other aspects can all greatly influence the formation and movement of sediment. Geologists must study the sediment to determine what it contains, how old it is, and how it got here. For this reason, geology is considered to be very critical to the study of the Earth and all its natural mineral resources.
Today, geology is still very much part of how humans view and interpret the world around them. Because the Earth is constantly being bombarded with geogenic (geological) factors, including tectonic shifts, massive volcanic eruptions, and plate movements, humans can use geology to decipher what happened and where. Even when studying the past on a small level, we can learn a lot about what to expect in the future because of the way the Earth works. Without geology, our understanding of nature would likely be limited, as well as the mineral resources that have been found and utilized by man.
