0:00 [Applause] [Music] the next question is related with the Ring of Fire so with reference to Ring
0:11 of Fire kinds of the following statements and we have been given here three statements right and let's take a look at what is Ring of Fire
0:17 from the term itself Ring of Fire I mean it's related with the volcanoes right the largest distribution of volcanoes in the world is there in this region in the
0:28 Pacific Ocean and that we call it as remove fire not only the case of the volcanoes rather than like say earthquakes plus the tsunamis their
0:36 distribution is Lars are there in this region ok now let's take a look at why this region is having large number of volcanoes or earthquake or tsunami right
0:45 now it's related with the plate boundaries and the the entire world is divided in the different plates and we are having three main types of plate
0:54 boundaries namely divergent plate boundary convergent plate boundary and transform plate boundary right from the term itself divergent means the plates
1:02 are diverging apart and the conversion means the plates are converging together right and transfer means they are slipping past each other right they are
1:10 not converging they are not diverging rather than they're slipping past each other anyway one of the one of the major plates in the world is Pacific plate
1:18 right and another major plate is Eurasian Plate then North American plate South American plate African plate and in those villains played as well as and
1:27 the second place plate these are regarded as the major plate right and we are also adding various minor plates namely Nazca plate Cosco plate and
1:36 Philippine plate plate inhale right in this region right in this Pacific plate region what happens is that the Pacific plate is converging with the eurasian
1:45 plate as well as the North American plate and the South American plate and also through in the case of endorsed syndrome plate
1:51 so what happens is that the Pacific plate is moving towards north and it's converging with the other plate boundary I mean other plates right now
2:00 let's take a look at the convergent plate boundaries now when we are having when the plates are converging the densest plate will always get subjected
2:10 right if you're comparing two plates one core dental plate oceanic plate the oceanic plate right the oceanic floor or the coastal region
2:18 the oceanic crust on region they are having largest I mean they're having more density than the continental crust all regions or can generally say the
2:25 continental plate so if you are having two plates converging together always the oceanic plate will be subjecting so in the Pacific plate like you know this
2:35 region the Pacific plate is an oceanic plate and these plates are can be regarded as the continental plate so what happens is that in these regions
2:43 the Pacific plate will get subjected right and Pacific plate will be moving I mean going under the the under the continental plate so what happens is
2:53 that like you know this subducting plate will get converted into a magma and it can rise up towards the surface creating volcanoes for that reason right in the
3:02 ring more fire region since we are having convergent plate boundary the Pacific plate is getting destroyed in the sense you know it's getting
3:09 subjected and it's getting converted into magma they're rising up towards the surface and resulting in the distribution of volcanoes Plus this
3:17 region right since it's an unstable region where they are colliding in this region the energy from the interior can get released in the form of earthquake
3:25 and for that recently this region is also prone to large number of earthquakes right now another specific property of this region where the plates
3:34 are subjecting under another plate is a formation of trenches and trenches they're kind of oceanic relief features and in this particular big picture you
3:42 can see the trench what happens is that or I mean like you know when d-sub when the plate are subjecting like that narrow grooves will be created will be
3:51 having a narrow basins with steep sides right and that we call it as trench so trenches they're generally associated with those regions where the oceanic
4:00 plate is subjecting under thee like the continental plate okay now coming back to the question with reference to Ring of Fire
4:07 control the following statement and we have been given here three statements right and there's none which of these statements given about we four are not
4:14 correct so this is a nod correct based question right so going to the first changement it is a sawn-off convergent plate boundary as you have seen earlier
4:22 right the Pacific plate is converging with different plates that Eurasian Plate North American plate South American plate as well as no
4:29 indoor seventh grade so the first statement is true and it cannot be the answer right so we can eliminate all the options with one in it right we can
4:37 eliminate a Pharisee so answer would be either B or it can be B right now going through the third one right since B is having three only going to the third one
4:47 it is associated with deep trenches again which is true right in the ring more fire regions we are having the conversion plate boundary so the oceanic
4:56 plate of the Pacific plate is getting destroyed or it is getting subjected right it is getting converted of magma those regions will be having deep
5:04 trenches so again the third one is correct right so B cannot be the answer and here answer comes out as D which is none of
5:11 the above that means all the three statements given here there too right going to the second one it is an active seismic and
5:18 volcanic zone which is again true plus we are also having large number of tsunamis taking place in this region right so here the answer comes out as D
5:26 which is none none of people [Music]
