Geology it is a natural science that studies the Earth. From the Greek, the term geology is formed by the words “geo” (Earth) and “logy” (study or science). The geologist is the professional and specialist in geology.
Importance of Geology
Through Geology it is possible to identify the origin, the age of the planet, the transformations it has undergone over time and also its geological formation.
In addition, through the tools and technologies used, it can predict the possible earthquakes and earthquakes that will happen across the globe and also predict climate changes.
The knowledge developed by geology is used in civil construction (dams, tunnels and roads); in exploration and exploitation of ores; in obtaining geothermal energy (energy produced by heat from the Earth's interior).
With regard to constructions, the presence of a geologist is essential, as he analyzes the soil, rocks and even predicts the environmental impact. Therefore, a geological and geotechnical survey of the areas destined for construction is carried out.
It is important to highlight that geology studies are focused on knowledge of our planet, improving the quality of life and our relationship with nature.
Given the importance of Geology studies, currently there are many undergraduate and graduate courses in the area. They involve knowledge of geography, history, astronomy, biology, ecology, paleontology, physics, mathematics and chemistry.
Study areas
Geology is a very broad area, and the main areas of study are:
- structural geology: study of the structure of the Earth.
- Historical Geology: study of geological ages, periods and ages.
- economic geology: study of mineral wealth.
- environmental geology: study of environmental impacts and ecological risks.
- Geophysics: study of the composition and physical properties of the elements.
- Geochemistry: study of the Earth's chemical composition and properties.
- Geomorphology: study of the forms of the earth's surface (relief).
- Petroleum Geology: study of the composition and properties of oil.
- Hydrogeology: study of underground water courses.
- Crystallography: study of crystals and solid structures formed by atoms.
- speleology: study of the geological formation of caves and natural cavities.
- Stratigraphy: study of the composition and structure of stratified rocks.
- sedimentology: studies of sediments accumulated on Earth derived from erosion.
- Topography: studies the geographic accidents present on the planet.
- astrogeology (Planetary Geology): Study of the various celestial bodies
- Seismology: study of earthquakes and movements of tectonic plates on the planet.
- volcanology: study of volcanoes and volcanic eruptions.
- Pedology: study of the formation and structure of soils.
- Petrography: study of rock analysis.
- Mineralogy: study of the composition and properties of minerals.
Geology Concepts
The main concepts developed by geology are related to the themes:
- Formation of Planet Earth
- Earth Structure and Layers
- Relief and geological formations
- tectonic plate movements
- Volcanoes, earthquakes, tsunamis
- Mineral Kingdom and Study of Fossils
- Oil, coal and natural gas
- The formation of soil and rocks
- Underground water deposits (groundwater and aquifers)
- The process of erosion, desertification and weathering
- Study of geological ages, periods and ages
