Physics - Geophysics
Geo-physics is a specialized branch of Earth science that studies the physical properties and physical process of the Earth.
Geophysicists use some quantitative methods and advance technology to analyze the Earth’s properties and process.
Technology of geophysics is used to locate mineral resources, mitigate natural hazards, and protection of the environment.
Geophysics has been carved out as an independent discipline from different subjects, such as, geology, physical geography, astronomy, meteorology, and physics.
Elements of Geophysics
Major elements those are studied under the geophysics are −
Shape of the Earth
Gravitational force of the Earth
Magnetic Fields of the Earth
Internal structure of the Earth
Composition of the Earth
Movement of the Earth’s plate (plate tectonics)
Fluid dynamics, etc.
Problems that Geophysicists Address
Following are the problem areas that geophysicists address −
Building highways and bridges
Mapping and exploration of mineral resources
Mapping and exploration of water
Mapping the earthquake and volcanic regions
Construction of dam and its safety
Forensic discovery (finding the buried dead bodies)
Techniques and Technology of Geophysics
Following are the major techniques and technology of geophysics −
Ground penetrating radar (GPR), etc.
Benefits of Geophysics
Following are the major benefits of geophysics −
Researching and studying archeological sites without destroying them
Designing environmental friendly urban architecture
Locating and judiciously exploiting natural resources
Helping in mitigation of natural hazards such as landslide, earthquake, etc
