LancangKuning – Geology is a field of science that studies the earth and everything that happens on earth. Geology studies the composition, structure, physical properties, and history of the formation of the earth. People who study geology are called geologists, and they have helped determine the age of the earth, which is estimated to be 4.5 billion years old, showed that the earth’s crust was split into moving tectonic plates, and helped find and manage the natural resources that exist on earth.
Understanding geology according to experts
Geology is the science that investigates the geological rock layers in the earth’s crust.
Geology is the science of earth which includes the origin, structure, composition and history of the earth (including the development of life) as well as the processes that have led to the current state of the earth like this.
Geology is the study of planet earth, especially regarding its constituent materials, the processes that occur in it, the results of the processes, the history of the planet Earth and the forms of life since the earth was formed.
Geology is a branch of science that studies all phenomena associated with the formation of the earth, the existence of the earth, and other phenomena related to natural forms.
Geology is the field of study of the earth and the earth as a whole group of studies, origin, structure, composition, history (including the development of life) and natural processes that already exist and are taking place, which made the state of the earth as it is today.
Branches of Geology
Mineralogy is a branch of geology that studies non-organic chemical compounds called minerals, studying their physical properties, chemical properties, location, how they are formed and their uses. The Mineralogy branch does not have a clear and agreed-upon general definition, but the basics should be understood by every geologist.
Petrology is a branch of geology that studies rocks and the conditions in which they are formed. There are three branches of petrology related to the three rock types studied, namely igneous, metamorphic and sedimentary rocks.
Petrology makes use of the fields of mineralogy, microscopic petrography, and chemical analysis to describe the texture, composition, structure and origin of rocks. Modern petrologists use the principles of geochemistry, geophysics, geochemical cycles, use of thermodynamic data and experiments to better understand the origin and composition of rocks.
Stratigraphy is a branch of geology that studies the history, composition, distribution and relative age of rocks and the interpretation of rock layers to explain the history of the earth. From the results of comparisons between different rock layers, Stratigraphy can be further developed into lithostratigraphy, biostratigraphy, and chronostratigraphy. Stratigraphy was studied to determine the extent of the spread of rock layers.
Historical geology is a branch of geology that studies the history of the earth and the history of events that have occurred on earth. To find out the history of the earth and these events, scientists will focus on everything that is in the earth’s crust, some of the unique features in the earth’s crust can be used as a ‘record’ in finding out about events in the past.
Volcanology is the branch of geology that studies the history and composition of volcanoes and their eruptions, magma, lava and related geological events. Volcanologists often visit volcanoes especially those that are active to observe and collect volcanological products. The purpose of volcanology is to predict volcanic eruptions, although not completely accurate, they can save the lives of many people.
Economic geology is a branch of geology that deals with earth materials and their use in economics or industry. These materials include precious metals, pure metals, non-metal minerals, stones for construction, petroleum, coal, water and so on.
Economic geology is not only studied and implemented by geologists, this branch of science is also an important concern for investors, stock experts, business people and other workers such as technicians, scientists and environmental conservators because economic geology has long-term benefits for the processing industry for society. , the economy and the environment.
