hey there i'm josh clark and in this
brainstuff i explain to you how the
tides work have you ever seen somebody
buried up to their neck and sand on the
beach and then the tide slowly comes in
and they drowned and wondered
I wonder how tides work well next time
you'll know and you can explain it to
that person as they wait to die
we need to be very careful here because
as French astronomer Francois arago once
said studying the tides is the tomb of
human curiosity which means it can break
your brain as you'll see there's a lot
of factors involved in creating the
tides here on earth but the big three
are the moon the Sun and the earth the
gravitational pull of all three of those
bodies interacting creates the tides the
biggest factor actually is the moon it
exerts about 2.2 times more power on the
tides than the Sun does so for once the
moon gets to one up the Sun it's kind of
a big deal to it imagine for our
purposes the earth is right here and the
moon is directly above it now they exert
a gravitational pull on one another and
since on the earth most things are
pinned down we have shoes buildings have
foundations stuff stays in place but the
oceans being literally fluid actually
can be pulled toward the moon and this
is what creates the tide the moon's here
it's pulling on the ocean at the top of
the earth creating a high tide on the
top and on the bottom another high tide
is created because the earth itself is
pulled toward the moon even though the
oceans down here have less gravitational
pull exerted on them being farthest away
from the moon so on the top and bottom
you have high tide because of the tidal
bulges and on the sides that are at
right angles to the moon you have low
tide because the oceans stretch thin
over the surface of the earth pretty
crazy huh so like I said the Sun also
exerts an influence on the tides but
it's less pronounced than the moon's see
it actually enhances or diminishes the
gravitational pull of the moon here on
earth when the Sun and the moon are in
alignment the Sun enhances the moon's
gravitational pull creating higher tides
than normal they're called spring tides
and they have
been on a full moon or a new moon now
when the Sun and the moon are at right
angles to one another with the earth
right about here the Sun diminishes the
gravitational pull of the moon on earth
creating lower than normal high tides
also called neap tides these happen on
the quarter moons because the earth and
the moon are constantly moving and
moving around one another there's a
constant movement from high tide to low
tide twice a day you get a high tide in
most places usually once every 12 hours
in 25 minutes
but this can vary and some places only
see a high tide once every 24 hours
those are called diurnal tides so this
is a daily occurrence actually twice
daily in most places but tidal waves
even though they have the word tide in
them pretty much but without the eat
they're not related to this
gravitational push and pull they're
usually the result of earthquakes
so that's tides hopefully we avoided
that a tomb of human curiosity and you
guys get it if not going back and
watching it again there's no shame in
that
it's pretty heavy stuff if you like this
