Geophysical waves are natural oscillations that occur within the Earth or its atmosphere. These waves can be generated by various phenomena, such as earthquakes, volcanic activity, or atmospheric disturbances. They travel through different mediums, including solid rock, water, and air, and can be classified into several types, such as seismic waves and ocean waves. Seismic waves, for example, are produced during an earthquake and can provide valuable information about the Earth's interior. Ocean waves, on the other hand, are generated by wind and can influence coastal erosion and marine ecosystems. Understanding geophysical waves is essential for fields like geology, oceanography, and meteorology.
