Magnetic Anomalies
Magnetic anomalies are variations in the Earth's magnetic field strength that differ from the expected normal values. They can occur due to geological features like mineral deposits, volcanic activity, or changes in the Earth's crust. Scientists study these anomalies to understand Earth's structure and processes, track changes over time, and locate resources like oil or minerals. By using instruments that measure magnetic fields, researchers can create maps that reveal these hidden geological features, enhancing our knowledge of the planet's history and composition.

Magnetic anomalies refer to areas where the Earth's magnetic field is different from what is expected based on standard models. These variations can be caused by differences in the Earth's crust, such as the presence of minerals or geological formations. For instance, certain rocks can be magnetized or influence magnetic fields, leading to stronger or weaker readings. Scientists study these anomalies to learn more about the Earth's structure, its history, and even to search for resources like minerals or oil. Essentially, they reveal hidden details about our planet's geological features through magnetic measurements.
