<span>Paleomagnetism is the science of studying the magnetic properties of rocks, sediments, and artifacts which developed in the rocks due to the power and orientation of the earth’s magnetic field while the rocks, sediments and artifacts were being formed. By studying the rocks and sediments scientists can determine when the history of earth’s magnetic field reversed.</span>
Paleomagnetism is the study of the history of earths magnetic field in ancient rocks and minerals.
Explanation:
This concept was revealed by the French physicist Achilles Delesse in 1849, who detected that certain magnetic minerals in rocks were associated parallel to Earth’s magnetic field. The study of paleomagnetism started in the 1940s when the British physicist Patrick M.S. Blackett designed a device for calculating the magnetic fields linked with magnetic minerals.
Nowadays, two more devices are used to study paleomagnetic materials: the spinner magnetometer and the cryogenic magnetometer. Each of these devices signifies a noteworthy development in the aptitude of a researcher to perceive and measure the magnetic field linked with a mineral.
The ring of fie is also known the pacific ring f fire and this zone is a major of basin in the pacific and here the major earthquake and the major volcanic eruption takes place and this an active ring or zone of subduction as the pacific plate is getting subdued by the north American plate and this plate is heavy oceanic plate. The chain of volcanoes arc covers an area of 40,000 km square.
