General Information about:
What is Geology?
The word geology comes from the Greek "geo" meaning earth and "logos" treaty or knowledge; therefore it’s defined as the science of earth and aims at understanding the evolution of the planet and its inhabitants, from ancient times to the present through the analysis of rocks.
What is Geophysics?
Geophysics is a science that derives from geology and deals with the study of the physical properties of the Earth. It Includes aspects such as the research of the internal composition of the planet, the heat flow from the inside of the Earth, the force of gravity that forms the gravitational field, the attraction magnetic force exerted by an ideal magnet inside the Earth creates the geomagnetic field, and propagation of seismic waves through the rocks of earth’s crust.
What is Geochemistry?
Geochemistry studies the origin, evolution and distribution of chemical elements on Earth which are contained in the rock-forming minerals and the products derived from it, as well as in living beings, water and atmosphere.
What is Environmental geology?
Environmental geology is the application of geological knowledge to environment research. It supports diagnosis and mitigation of pollution problems, minimizing possible environment degradation or maximizing the possibility of correct use of natural or modified environment. Also deals with natural phenomenon dangers and risks (geologic and hydrometeorological) and anthropogenic (caused by human).
What is Hydrogeology?
It is the comprehensive study of groundwater, its distribution and evolution through time and space, under regional geology.
Danger and risk
- Danger or threat: they refer to the probability of potentially harmful phenomenon occurrence in a period of time. Danger potential is measured with intensity and return time.
- Exposure: it is the number of people, possessions, wealth and infrastructure susceptible of being damaged.
- Vulnerability: it refers to the systems exposed proclivity (human settlements, infrastructure) of being damaged by a disturbing phenomenon effect.
- Risk: it concerns with the probability of a danger to become a disaster. Possibility combination that an event occurs and its negative consequences. Factors that composed it are threat and vulnerability.
What is Geotechnics?
It is the branch of geology that deals with the application of geological principles in the research of natural materials –such as rocks- that form the earth crust involved in the design, construction and operation of civil engineering projects, as highways, railways, bridges, dams, pipelines, aqueducts, dwelling units, confinement sites and buildings in general.
Remote sensing
Mexican Geological Survey (SGM), is in charged of explore country’s mineral resources to achieve their optimal use. Remote sensing is used to satellite images interpretation as this let us visualize large areas jointly, instantly and synoptically.
What is Coal?
It is a black sedimentary rock, carbon-rich, and variable amounts of elements such as hydrogen, sulfur, oxygen and nitrogen. It can be easily burn and it is one of the most used fossil fuels.
