The Ring of Fire

Audio Transcript Auto-generated

• 00:01 - 00:01

  Hi, everybody.

• 00:02 - 00:04

  So today we're going to learn about the ring off

• 00:04 - 00:07

  fire. Now, do you know anything about the ring of

• 00:07 - 00:09

  Fire? Pause this video and have a discussion.

• 00:10 - 00:11

  What is the ring of fire?

• 00:12 - 00:12

  What do you think?

• 00:16 - 00:18

  Well, have a look.

• 00:19 - 00:23

  So? So the Ring of fire is a ship line

• 00:23 - 00:25

  that looks a little bit like horseshoe.

• 00:26 - 00:28

  Alright. On on this map, it is highlighted in red

• 00:30 - 00:30

  on Dhe.

• 00:30 - 00:34

  It is home to around 75% off the world's volcanoes.

• 00:35 - 00:37

  So along that red line that you can see on

• 00:37 - 00:40

  the map is home to 75% of the world's volcanoes.

• 00:41 - 00:44

  Now it is also home to 90% off the world's

• 00:45 - 00:49

  earthquakes. Now it's a bit off a coincidence that it's

• 00:49 - 00:52

  home. Tow the majority of the volcanoes that are in

• 00:52 - 00:52

  the world.

• 00:54 - 00:56

  Let's have a look as to why that is so

• 01:00 - 01:02

  So. The area is a 25,000 mine line of volcanoes,

• 01:03 - 01:06

  tremors and earthquakes around the edge off the Pacific Ocean.

• 01:06 - 01:08

  Now we've done a little bit of work on ocean,

• 01:08 - 01:11

  so hopefully you can pinpoint exactly where that is on

• 01:12 - 01:12

  them up.

• 01:12 - 01:15

  If you can't, I would Google the ring of Fire

• 01:15 - 01:18

  and see which countries are located near the Pacific Ocean.

• 01:20 - 01:20

  Have a look at the next video.

• 01:22 - 01:23

  Hi, everybody.

• 01:23 - 01:23

  Sorry about that.

• 01:24 - 01:26

  Mrs. Marshall was having a few technical difficulty, so I

• 01:26 - 01:27

  was needed next door.

• 01:27 - 01:29

  So let's get our slide back open.

• 01:29 - 01:33

  So tectonic plates are what are under the ground.

• 01:34 - 01:34

  All right.

• 01:34 - 01:38

  So along that red line that you can see the

• 01:38 - 01:38

  ring of fire underneath.

• 01:40 - 01:42

  All of the different surfaces that you have learned about

• 01:43 - 01:45

  the last couple of days are what's known as tectonic

• 01:45 - 01:49

  plates. All right, so if you imagine plea, it's together.

• 01:50 - 01:51

  Make no noise.

• 01:51 - 01:52

  All right.

• 01:52 - 01:53

  They're very quiet.

• 01:53 - 01:55

  But you imagine you put plates in the dishwasher.

• 01:56 - 01:58

  They will make a lot, a lot, a lot of

• 01:58 - 01:59

  noise. All right.

• 01:59 - 02:01

  And when tectonic plates, they bring it together.

• 02:02 - 02:05

  All right, I'm when the vibrations get to a certain

• 02:05 - 02:09

  level, that is what causes the different layers, then to

• 02:10 - 02:11

  erupt. All right.

• 02:11 - 02:15

  So the volcano eruption is caused by the tectonic plates

• 02:16 - 02:19

  which rubbed together and caused the rest off structure to

• 02:20 - 02:21

  collapse on explode.

• 02:21 - 02:22

  All right.

• 02:23 - 02:24

  Oh, why do earthquakes happen?

• 02:25 - 02:26

  Well, I just explained that a lot of a lot.

• 02:26 - 02:28

  So the earth's crust is made up in lots of

• 02:28 - 02:31

  pieces. The edge of the edges of these pieces rub

• 02:31 - 02:31

  against each other.

• 02:32 - 02:34

  And this can cause sudden movements which lead to earth

• 02:34 - 02:35

  tremors or earthquakes.

• 02:35 - 02:38

  These pieces of Earth's crossed or called tectonic plates, and

• 02:38 - 02:40

  they make a jigsaw covering earth.

• 02:40 - 02:43

  Now, if you look at that map, all right, the

• 02:43 - 02:45

  red lines, those like little jigsaw pieces.

• 02:46 - 02:46

  All right.

• 02:46 - 02:50

  And those air different tectonic plates that are underneath the

• 02:50 - 02:51

  ground surface.

• 02:51 - 02:54

  All right, on those volcanoes that are located near those

• 02:55 - 02:55

  tectonic plates.

• 02:56 - 03:00

  If the vibrations get too much, then the volcano that

• 03:00 - 03:03

  is near those tectonic plates underneath the ground that's going

• 03:03 - 03:04

  to cause that volcano to erupt.

• 03:04 - 03:10

  All right, so where earthquakes happen, So this is a

• 03:10 - 03:13

  map that shows the earthquake hotspots around the world.

• 03:14 - 03:16

  All right, so what do you notice about that map?

• 03:16 - 03:17

  All right.

• 03:17 - 03:18

  So we know where the ring of fire is.

• 03:18 - 03:19

  We can see the red lines.

• 03:21 - 03:26

  The volcanoes are located near the Ring of Fire.

• 03:27 - 03:29

  The majority off those volcanoes on earth.

• 03:30 - 03:32

  Quake hotspots that happen in the world.

• 03:32 - 03:35

  Majority of them that happened are located near the tectonic

• 03:35 - 03:36

  plates. Why do you reckon that is?

• 03:37 - 03:41

  Well, if there's a volcano near one of the tectonic

• 03:41 - 03:43

  plates that are underneath the ground, then that's going to

• 03:43 - 03:44

  cause it.

• 03:44 - 03:46

  If the plea, it's air vibrating too much, that's going

• 03:46 - 03:48

  to cause the volcano to erupt, or that's gonna cause

• 03:48 - 03:49

  an earthquake to happen.

• 03:50 - 03:51

  All right, so what I would like you to do

• 03:52 - 03:53

  in our guys is have a look at this slide.

• 03:54 - 03:55

  What makes the ring of fire so special?

• 03:56 - 03:58

  Well, one way that tectonic plates, mate and move is

• 03:59 - 04:01

  when one slides under the other, creating what is known

• 04:01 - 04:02

  as a subduction zone.

• 04:02 - 04:05

  All right, so rather than the tectonic plates next to

• 04:05 - 04:08

  each other vibrating, if one slides underneath than those vibrations

• 04:09 - 04:12

  are going to cause on eruption or earthquake.

• 04:14 - 04:15

  So the boundary off the ring of fire is mostly

• 04:16 - 04:18

  subduction zones, which are more likely to cause earthquakes.

• 04:18 - 04:21

  The subject subduction also leaves behind trenches.

• 04:21 - 04:23

  All right, so what I would like you doing are

• 04:23 - 04:25

  you guys I would like you to have a go

• 04:25 - 04:29

  at labeling the different volcanoes and earthquakes on the worksheet.

• 04:30 - 04:31

  All right, so you can save the ring of fire

• 04:32 - 04:34

  on Dhe, you will have toe research online.

• 04:35 - 04:38

  Where they're those volcanoes or those earthquakes.

• 04:39 - 04:39

  No more.

• 04:39 - 04:39

  That's asking.

• 04:40 - 04:41

  You are located.

• 04:41 - 04:43

  All right, So have a good that worksheet, guys.

• 04:43 - 04:45

  And hopefully you learn a bit more about what the

• 04:45 - 04:46

  ring of fire is on.

• 04:47 - 04:50

  How that plays a major part off volcanoes in the

• 04:51 - 04:52

  world. All right, bye for now, guys.
