Paleomagnetism

Choose the Correct Answer

Correct Answer : Option b

Explanation
Statement 1 is correct: Paleomagnetism is the study of the Earth's magnetic field preserved in rocks. The discovery that some minerals, at the time of their formation, can become magnetized parallel to the Earth's magnetic field was made in the nineteenth century.

Statement 2 is correct: The record of the strength and direction of Earth’s magnetic field (paleomagnetism, or fossil magnetism) is an important source of our knowledge about the Earth’s evolution throughout the entire geological history. This record is preserved by many rocks from the time of their formation. The paleomagnetic data have played an instrumental role in deciphering the history of our planet including a decisive evidence for continental drift and global plate tectonics. The data have also been crucial for better understanding the problems of regional and local tectonics, geodynamics, and thermal history of our planet.

Statement 3 is not correct: Palaeomagnetism primarily deals with reconstructing past magnetic field orientations and geomagnetic reversals. While Paleomagnetic data can provide insights into the timing and patterns of past magnetic pole reversals, it does not offer a reliable method for predicting when or how future reversals might occur.
