00:00why is the pacific ocean so vast and landlocked what's the mystery the pacific ocean is super big

00:10so big that it covers more space than all the continents put together it's so deep and wide

00:16that there are many secrets hiding under the water but there's one mystery about it that might

00:22surprise you to learn about this mystery you should look carefully at a world map have you

00:29ever looked closely at the world map if you did you might have wondered why is the pacific ocean so

00:36vast compared to the other oceans stretching almost halfway around the globe have you ever

00:42wondered why the pacific ocean is so different from the other oceans if you look at a world map

00:48you'll see lots of land called continents on one side but why isn't there a huge land mass covering

00:55the big pacific ocean have you thought about why the pacific ocean is the biggest and feels kind of

01:01empty or why can it be more dangerous than other oceans if you want to know the answers keep watching

01:08the video until the end let's start if you look at the world map you'll notice most of the continents

01:16are on one side and on the other side there's an enormous expanse of blue the pacific ocean taking

01:23up almost an entire hemisphere have you ever wondered why there's only the pacific ocean on

01:29one side of the earth and all the land with continents on the other side it might seem a

01:34little strange right the pacific ocean isn't just a small body of water it's huge and makes up about

01:4130 percent of everything on earth even if you put all seven continents together they wouldn't be as big

01:48as the pacific ocean a long time ago all the continents were joined together in one big landmass

01:55covering almost 200 million square kilometers that special time is called pangea a long time ago there

02:04was a big supercontinent called pangea and around it was a giant ocean named panthalassa it was like a

02:11huge water world but then something changed the shape of the earth's land this change happened

02:19because the pieces of the earth's crust called tectonic plates started to move very slowly

02:25as they moved pangea began to break apart into different land pieces

02:31in 1912 a scientist named alfred wegener from germany came up with an idea called the continental drift theory

02:38he said that all the continents used to be connected and then slowly drifted apart

02:44at first many scientists didn't believe him but over time they realized he was right and his idea

02:51became accepted as the truth imagine all the continents on earth are like big puzzle pieces

02:58a long long time ago all these puzzle pieces were stuck together to make one giant land called pangea

03:05over many millions of years the puzzle pieces slowly moved apart and now we have the continents we see

03:12today but this movement doesn't stop every few million years the continents might move closer again

03:19and join together or break apart into even smaller pieces so when i mention names like pangea or panthalassa

03:27while talking about the pacific ocean it's because a long time ago all the land and oceans were connected

03:33differently and the earth's surface keeps changing over time hi friends do you know why the biggest ocean

03:41in the world feels so lonely it's because the continents the giant land pieces are slowly moving away from

03:48each other a long time ago about 4.5 billion years ago the earth started changing and the continents began

03:57to drift apart and come back together again scientists say this has happened three times before and it will

04:04happen again someday you might wonder how these huge land pieces can move all by themselves a scientist

04:12named wegener explained how this happens through his theory of continental drift which says the continents

04:18slowly shift over earth's surface carried by movements in the planet's underlying layers he explained

04:24that the reason continents sometimes break apart and then come back together is because of big pieces

04:30of the earth's surface called tectonic plates these plates move because of heat deep inside the earth

04:37sometimes the plates move apart from each other which is called a divergent boundary when this happens

04:44the land separates and water can fill the space between them the way these plates move can change over time

04:51this big body of water can be a huge ocean or a small sea because a new layer of rock called oceanic crust

04:59was made about 200 million years ago because of this the one big ocean that used to cover everything

05:06called panthalassa changed into the five oceans we see today so all the oceans are still connected as one

05:14big ocean friends this change happens very slowly so slowly that we don't see it happening

05:22for example africa is slowly splitting into two parts but we hardly notice it happening

05:29maybe someday a new big ocean will form in africa and it will be called the earth's sixth ocean

05:36friends there's another way the earth's crust moves called a convergent boundary

05:41that's when two big pieces of the earth's crust push toward each other

05:46when they do this they can make huge mountains

05:49the tallest and most famous example is the himalayas these mountains formed because the indian land

05:56pushed into the eurasian land this pushing is still happening today so the himalayas are getting a

06:03little taller each year about two centimeters the big pieces of the earth's crust called plates are

06:10slowly moving by tiny amounts just centimeters you might wonder why i'm talking about these plates and

06:17how they relate to the pacific ocean being so empty the way these plates move affects everything on earth

06:24the emptiness and size of the pacific ocean are mostly due to these moving plates

06:30under the ocean there's a huge plate called the pacific plate and it's always pushing against

06:35other plates around it most of the time this pushing happens at the edges of the ocean which

06:42are called tectonic plate boundaries imagine the earth's outer layer is made up of big pieces

06:48called plates like giant puzzle pieces these plates move very slowly just a tiny bit at a time only a

06:56few centimeters you might wonder why i'm talking about these plates and how they make the pacific ocean

07:02so big and empty well the way these plates move changes the shape of the earth the pacific ocean is so

07:11big and open because of these moving plates under the ocean there's a large plate called the pacific

07:17plate and it's always pushing against other plates around it most of the time this pushing happens at

07:24the edges of the ocean which are called mid-ocean ridges imagine a big rocky circle all around the pacific

07:32ocean made up of mountains and volcanoes that's called the ring of fire it's like a giant wall made

07:39of hot bubbling volcanoes and tall mountains this circle is about 400 kilometers long and 500 kilometers

07:47wide and it goes all around the ocean because so many huge pieces of earth's crust called tectonic plates

07:55bump into each other there it's the most active place on earth for earthquakes and volcanoes

08:01about three out of four volcanic eruptions and earthquakes happen in the ring of fire

08:07since japan is right inside this circle it often feels earthquakes and sees volcanic eruptions

08:13you might wonder why the pacific ocean feels calm and empty even though the pieces of the earth's crust

08:19there are moving around a lot scientists say there are two main reasons for this the first reason is

08:26called the ring of fire it's like a big border around the pacific ocean so even though the plates are

08:33moving new land isn't forming there underneath the ocean is a really big part of the earth's crust

08:40called the pacific plate this huge plate is always moving and pushing against other smaller plates

08:46nearby because it's so big and heavy it puts pressure on the smaller plates around it no there isn't a

08:54continent there because of how the earth's plates are arranged the second reason is inside the pacific

09:01plate itself usually under oceans many different pieces of the earth's crust bump into each other

09:08which can help form continents but under the pacific ocean there's only one big piece

09:14so continents don't form there the small islands that appear along the edges of this big plate are

09:20usually tiny and don't last forever sometimes they sink or change over time because of movement in the

09:28earth's crust and there are other reasons too like erosion volcanic activity and changes in sea level that

09:35reshaped the ocean floor the islands in the pacific ocean are very small and far away from each other

09:43because they are so spread out it's hard for big cities or many people to live and work there

09:49this is why the pacific ocean feels like a lonely place so friends after watching this tell me in the
