Earth's Inner Core May Take Reverse Direction!
By Tech Tudum
Earth's inner core
may have
temporarily stopped rotating
relative to the mantle and surface
The direction of the
inner core's rotation
may now be
reversing
This could be part of a
70-year-long cycle
that may influence the length of
Earth's days and its magnetic
field
Studies have suggested that the
inner core rotates within the liquid outer core
, compelled by the outer core's magnetic torque
The mantle's immense gravitational pull
may also apply an
erratic brake
on the inner core's rotation, causing it to
oscillate
Evidence for the
inner core's fluctuating
rotation first
emerged in 1996
Researchers have questioned previous conclusions and some suggest the
core spins slower or doesn't spin differently at all
The new study, using
global seismic data
from the
1990s
, made a
surprising observation
Some researchers are skeptical of these
findings and further research
is needed to confirm them.
