Geophysicists are scientists who study the Earth using principles of physics. They investigate various physical properties of the Earth, such as its magnetic and gravitational fields, seismic activity, and heat flow. Their work helps us understand natural phenomena like earthquakes, volcanic eruptions, and the structure of the Earth's interior. These scientists often use advanced technology and tools, including seismographs and satellite imagery, to collect data. Their research is crucial for resource exploration, environmental protection, and understanding climate change. By analyzing the Earth's processes, geophysicists contribute to safer construction practices and better disaster preparedness.
