Geophysical data refers to information collected about the Earth's physical properties and processes. This data can include measurements of the Earth's magnetic field, gravity, seismic activity, and temperature variations. Scientists use various tools and techniques, such as satellites, seismographs, and ground-penetrating radar, to gather this information, which helps in understanding the Earth's structure and behavior. This type of data is crucial for various applications, including natural resource exploration, environmental monitoring, and earthquake prediction. By analyzing geophysical data, researchers can gain insights into geological formations, assess risks, and make informed decisions regarding land use and resource management.
