Earth's Core Has Stopped Spinning, What Now?

tell me the truth you probably think

that Earth's magnetic field is caused by

a big ball of solid iron in the middle

of the planet right yep I mean the inner

core but the problem here is that in the

inner core the temperatures are so high

that the very magnetism of iron itself

is changed once such a temperature which

is called the curry point is reached

atoms aren't able to align to a magnetic

point

anymore so in reality Earth's magnetic

field is created by the swirling outer

core and magnetism there is more than 50

times greater than it is on the surface

the liquid iron in the outer core

conducts electricity perfectly which

helps it create electrical currents

driving the magnetic

field without it our planet wouldn't be

able to hold onto its atmosphere as a

result we'd lose our main protection

from extremely dangerous space radiation

but it wasn't the outer core that

surprised us not so long ago scientists

say Earth's inner core has likely

stopped rotating relative to the mantle

and the surface of the planet even more

exciting it could even go into reverse

but let's look into the details Earth is

formed of the crust mantle and outer and

inner cores the solid inner core is

about 3,2 200 M below the crust it's

separated from the semisolid mantle by

the liquid outer core yep the one thanks

to which we have the magnetic field and

since this outer core is liquid it

allows the inner core to rotate at a

speed different from the speed of our

planet's rotation Earth's core has a

radius of 2,200 mil and is almost as

large as Mars it mostly consists of iron

and nickel and makes up around 1/3 of

Earth's mass the spin of the inner core

is powered by the outer core it turns

out that the slowing of the core started

in

2009 since that time seismic records

which had previously been changing

continuously have shown little

difference and it makes scientists

conclude that the inner cores rotation

has paused but we're nowhere near the

scenario of a disaster movie apparently

the inner core taking a temporary break

is part of its 70E long cycle during

this cycle the core switches directions

every 35 years or so this might

influence Earth's magnetic field and the

length of the day but some researchers

are skeptical about it and some

scientists even go as far to say that

the inner core isn't moving at all okay

but what would happen if Earth's core

indeed stopped rotating well if it was

was the solid inner core the answer

would be nothing dramatic even if it

didn't just reverse the direction of its

movement like it's doing at the moment

but stopped altogether it would just

impact the speed of Earth's rotation it

slow down making our days longer plus

with time it could probably degrade our

planet's magnetic field and it would be

bad news but not as bad as they would be

if the outer core stopped spinning as

you already know without this layer's

rotation Earth would have to kiss its

magnetic field goodbye and that's how

the downfall of the planet would begin

things would start getting shaky the

tectonic plates would begin to slam into

each other you know like when you're

going by bus and the driver suddenly

hits the brakes and you end up flying

into other unfortunate passengers yeah

like that the sudden Collision of

tectonic plates would trigger

destructive earthquakes along the plate

boundaries all all over the world they

would wipe buildings Bridges and Roads

off the face of the earth water systems

electricity and phone lines would also

be destroyed but the worst would be yet

to come without the protective magnetic

field Cosmic radiation would start

hitting the surface of our planet these

high energy particles coming from the

Sun would come in contact with oxygen

and nitrogen in our atmosphere

effectively destroying our ozone layer

this this would allow even more cosmic

rays to reach the surface of Earth the

radiation would damage all kinds of

electronic devices and disable power

grids and the consequences would be

disastrous not only for people but for

all forms of life on Earth the

stationary core would make navigating

the planet more difficult people would

have to start using trail maps again

since compasses would become useless it

would also make it harder if not

impossible for migratory animals to find

their way Birds would keep losing

directions and turtles would fail to

find beaches where they used to lay eggs

luckily we don't need to worry about

this kind of apocalyptic scenario the

planet's outer core is very unlikely to

stop anytime soon if ever now do you

want to find out something cool then

listen to this our planet's inner core

has a core of its own scientists have

made this discovery just recently

they've learned that this core in the

core could have developed around 500

million years ago as a result of some

dramatic geological changes what about

other planets do they have the same

cores as Earth let's look at Mars one of

our planet's closest neighbors its heart

is the size of the moon it's also almost

twice as dense scientists made this

conclusion after they got some data

about the first observed Mars quake and

meteorite in

impact both these events were captured

by NASA's Insight Lander which had been

monitoring seismic activity on the red

planet for 4 years the researchers also

estimated that Mars's core is probably

made mostly of a liquid iron alloy with

a smattering of hydrogen oxygen and

carbon one day Mars probably had a nice

rotating core that supported the

planet's magnetic field there could be

warm oceans swarming with life

but then something must have happened

and on one terrible day the red planet's

core froze in place it could have led to

the weakening of Mars's once strong

magnetic field its atmosphere was taken

away by powerful solar winds hitting the

planet at a speed of several hundred mph

and the red planet turned into a

lifeless dry desert now what about gas

giants let's take the largest and the

most massive planet in the Solar System

Jupiter it's twice as massive as all

other planets of the solar system

combined almost 1300 Earths could fit

into this huge thing Jupiter also has

the shortest day in the solar system it

lasts a mere 10 Earth hours at the same

time the gas giant needs 12 Earth years

to complete an orbit around the sun

Jupiter most likely appeared at the same

time when the rest of our solar system

formed about 4.5 billion years ago

probably the coolest thing about this

gas giant is that it has the same

ingredients as a star but unfortunately

or should I say luckily it hasn't grown

massive enough to ignite scientists

don't know for sure what Jupiter's core

looks like according to most theories

the gas giant has a dense core made up

of heavy elements during its formation

it was probably a collection of debris

icy material and other small objects

like comets and asteroids zipping around

thanks to their Mutual gravity these

bits of matter clumped together forming

larger chunks which later turned into

Jupiter's core at one point it became

massive enough to start attracting

hydrogen and helium more and more gases

accumulated around the core until what

we today know as Jupiter appeared

there's also a possibility that Jupiter

doesn't have a core at all or it might

have existed once but since then it's

eroded away hopefully we'll find out the

answers to these questions soon enough

since Juno NASA's space probe is

orbiting Jupiter collecting data about

its gravitational and magnetic

fields so what about the gas Giant's

magnetic field you may ask does it even

exist oh don't worry Jupiter is

surrounded by a ginor ormous magnetic

field called the

magnetosphere that's it for today so hey
