paleomagnetic उदाहरण वाक्य
उदाहरण वाक्य
- These may be paleomagnetic remnants of a former global magnetic field, or may be due to meteor impacts or other local phenomena.
- The pace of ancient convergence can be determined with paleomagnetic measurements, while the present rate of convergence can be measured with GPS.
- Paleomagnetic Euler rotations ( rotation poles and angles ) and the mantle structures, however, could provide clues to this longstanding challenge.
- Older than that we run out of seafloor, so other ways have to be used, like paleomagnetic poles and fit of geological observations.
- The goal of much paleomagnetic research is to assemble poles in APWPs for the different continental fragments, which is the first step in reconstructing the paleogeography.
- Although paleomagnetic evidence can be used to rule out the 1850s as the age of Cinder Cone, it does not provide an actual age for its eruption.
- For some time one of the blocks was believed to be the continent of Amazonia, but paleomagnetic evidence has now proven that this is not the case.
- Paleomagnetic studies showed that the earth's field reversed every half million years or so, but in a fairly random way and with early patterns more chaotic.
- In order to collect paleomagnetic data dating beyond 200 mya, scientists turn to magnetite-bearing samples on land to reconstruct the Earth's ancient field orientation.
- In the past four decades much paleomagnetic data about seafloor ages ( up to ~ ) has been collected and is useful in estimating the age of geologic sections.
