Geofysiisissä

Geofysiisissä is the Finnish term for geophysics. Geophysics is a broad scientific discipline that employs the principles of physics to study the Earth. It encompasses a wide range of investigations into the planet's physical properties and processes. Geoscientists in this field use various methods to probe the Earth's interior, its atmosphere, and its oceans without direct observation, relying on indirect measurements and mathematical modeling.

Key areas within geophysics include seismology, the study of earthquakes and seismic waves, which helps map the Earth's internal structure. Gravity is also studied to understand variations in mass distribution within the Earth, revealing features like subsurface density anomalies. Magnetism is another crucial aspect, investigating the Earth's magnetic field, its origin, and its historical variations, which is vital for navigation and understanding the planet's protective shield.

Other important sub-disciplines include geodesy, the science of measuring and understanding the Earth's geometric shape, orientation in space, and gravitational field. Geomagnetism focuses on the Earth's magnetic field, while paleomagnetism studies the record of Earth's magnetic field in rocks. Exploration geophysics is a practical application, using geophysical techniques to locate natural resources like oil, gas, and minerals, as well as for environmental and engineering studies. The ultimate goal of geophysics is to understand the dynamic processes that shape our planet, from its core to its surface and beyond.
