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. The people who study geology are called geologists and they helped determine the age of the earth, which is estimated to be 4.5 billion years old, they showed that the earth’s crust was divided into moving tectonic plates and helped to find and manage the natural resources that exist on earth.
Understanding geology according to experts
Geology is the science that explores the geological layers of rocks in the earth’s crust.
Geology is the science of the earth that includes the origin, structure, composition and history of the earth (including the development of life), as well as the processes that led to the current state of the earth thus.
Geology is the study of planet Earth, especially its constituent materials, the processes that take place on it, the results of the processes, the history of planet Earth and the life forms from Earth.
Geology is a branch of science that studies all the phenomena related to the formation of the earth, the existence of the earth and other phenomena related to the physical forms.
Geology is the field of study of the earth and the earth as a whole a group of studies, origin, structure, composition, history (including the development of life) and natural processes that already exist and take 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 field of Mineralogy does not have a clear and agreed general definition, but the basics must be understood by every geologist.
Petrology is a branch of geology that studies rocks and the conditions under which they are formed. There are three branches of petrology related to the three types of rocks studied, namely igneous, metamorphic and sedimentary rocks.
Petrology uses 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, the 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, biostratography, and chronostratigraphy. Stratigraphy was studied to determine the extent of rock spread.
Historical geology is a branch of geology that studies the history of the earth and the history of events that have taken place on earth. To learn the history of the earth and these facts, scientists will focus on everything in the earth’s crust, some of the unique features of the earth’s crust can be used as a “record” to discover 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 in observing and collecting volcanic products. The goal of volcanology is to predict volcanic eruptions, although they are not entirely accurate, they can save many lives.
Economic geology is a branch of geology that deals with the materials of the earth and their use in economics or industry. These materials include precious metals, pure metals, non-metallic minerals, building stones, oil, coal, water and so on.
Economic geology is not only studied and applied by geologists, this branch of science is also a major concern for investors, stock experts, entrepreneurs and other workers such as technicians, scientists and environmentalists, because economic geology has long-term benefits for processing industry. for society., the economy and the environment.
