the earth rotates on an axis and deep under its crust so does its core however experts now say
00:09
their observations have revealed that the inner core is changing speed and it could actually
00:13
change the length of our days earth's inner core is located around 3 000 miles underground and is
00:19
around two-thirds the size of the moon it consists of molten nickel and iron and by looking at seismic
00:24
data which provides an insight into the reverberations that ripple through the core geoscientists
00:28
have been able to perceive the movement of the inner core finding it's slowing down they say the
00:33
slowing process began in 2010 likely caused by either the outer core's movement or some gravitational
00:39
forces with the researchers telling usa today when i first saw the seismograms that hinted at this
00:44
change i was stumped but when we found two dozen more observations signaling the same pattern the
00:49
result was inescapable so should we be worried probably not here's how the researchers explained
00:54
it to usc journalists it would be very hard to notice on the order of a thousandth of a second
00:59
almost lost in the noise of the turning oceans and atmosphere
