geofüsiikat

Geofysiikka is the study of the physical processes and phenomena of the Earth and its environment in space. It encompasses a wide range of scientific disciplines that apply the principles of physics to understand our planet. Geoscientists use geophysics to investigate the Earth's interior, its magnetic field, its atmosphere, and the oceans.

Key areas within geophysics include seismology, which studies earthquakes and seismic waves to map the Earth's internal structure. Geomagnetism investigates the Earth's magnetic field, its origins, and its effects. Gravity studies the Earth's gravitational field, providing insights into mass distribution within the planet. Other important branches include atmospheric physics, dealing with the physical processes in the atmosphere, and ocean physics, focusing on the physical properties and dynamics of the oceans.

Geophysical methods are crucial for resource exploration, such as oil, gas, and minerals, by detecting subsurface anomalies. They are also vital for understanding and predicting natural hazards like earthquakes, volcanic eruptions, and tsunamis. Furthermore, geophysics plays a significant role in climate research and understanding space weather, which can impact satellite operations and communication systems. The data gathered through geophysical surveys and instruments helps build comprehensive models of the Earth system, from its core to the exosphere.
