geomagnetic reversal उदाहरण वाक्य

Because the field has reversed directions at irregular intervals throughout its history, the pattern of geomagnetic reversals in the ocean crust can be used as an indicator of age.
Occurring at the same time as a geomagnetic reversal, the flares would be devastating to the planet, with the first wiping out North America and the second everything else.
What do you guys think of the dangers caused by solar weather ( we seem to only have a Solar wind article . ) Geomagnetic storms Geomagnetic reversal and Meteor showers.
In the last 50, 000 years there have been no geomagnetic reversals, and no known global polarity excursions . ( Local excursions would have had no significant effect on 14C production .)
Unlike geomagnetic reversals, which are easily detected by the change in field direction, the relatively short-lived excursions can be easily overlooked in long duration, coarsely resolved, records of past geomagnetic field intensity.

"' Antoine Joseph Bernard Brunhes "'( 3 July 1867 10 May 1910 ) was a geophysicist known for his pioneering work in paleomagnetism, in particular, his 1906 discovery of geomagnetic reversal.
In a geomagnetic reversal, the Earth's geomagnetic field weakens and stays weak for thousands of years during the transition to the opposite magnetic polarity and then regains strength as the reversal completes.
*first explain what geomagnetic reversals are, and then mention the two or three types ( I think Aitken mentions two types of global ones, but you could simplify to two-- global and polarity );
Geomagnetic reversal has been a useful method for timing events on a geologic time scale; events like Plate tectonics were only able to be put into a proper temporal relationship once Geomagnetic reversal was understood.
