paleomagnetism
/ˌpeɪ.li.əʊˈmæɡ.nə.tɪ.zəm/ IELTSAcademic
noun
the study of Earth's past magnetic field, as recorded in rocks, lava, and sediments. Scientists use it to learn about plate movement and Earth's history.
- Paleomagnetism helps scientists study ancient continents.
- The rock shows evidence of paleomagnetism.
- Paleomagnetism can reveal past changes in Earth's magnetic field.
Adinary Nuance
Paleomagnetism is not the same as magnetism in general. Magnetism is the force itself, while paleomagnetism is the study of ancient magnetic signals in rocks. It is also different from geomagnetism, which focuses on Earth’s magnetic field more broadly. Scientists use paleomagnetism to understand old field directions, not to describe everyday magnets.
