what feature, marked with an a in figure 1, is responsible for creating the oceanic plateau? This is a topic that many people are looking for. amritsang.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, amritsang.org would like to introduce to you Science 10: Lesson 3 Processes that Occur Along the Plate Boundaries PART 1. Following along are instructions in the video below:
Students welcome to grade 10 science lessons and im your teacher mom. Marian soriano soriano music you have learned from our previous lesson that litospheric plates are slowly moving different directions music this movement of plates can be classified into three types of plate boundaries. Namely convergent plate boundary divergent plate boundary and transform fault plate boundary music along the plate margins earthquakes volcanoes and mountain ranges are being formed.
But what other geologic activities may be formed in the different types of plate boundaries. What will happen if two different lithospheric plates collide why do we need to study these different geologic processes. Lets find out in todays lesson applause processes that occur along the plate boundaries part 1 remember that there are two types of crust continental crust and oceanic crust though the oceanic crust is thinner than the continental crust oceanic crust is denser than the continental crust this idea about crust is very important to help you understand the geologic processes occurring along the different types of plate boundaries lets start with convergent plate boundary.
The geologic processes that will be formed along this type of plate boundary depends on the material of plates that are colliding. We have the convergence of oceanic to continental plates convergence of oceanic to oceanic plates and lastly convergence of continental to continental plates lets take a look on each type of convergent plate boundary music oceanic continental convergent plate boundaries music this figure shows the convergence between oceanic crustal plate and continental crustal as two different plates collide the leading edge of the oceanic plate bends towards the mantle since it is denser than the continental plate the bending of the denser plate towards the mantle is called subduction process since the mantle is hotter than the crust. The tendency of the subducted leading edge of the oceanic crust will be melted.
Forming magma. Addition of volatile materials. Such as water.

Will cause the magma to become less dense this allows the magma to rise and reach the edge of the continental crust plate. Forming volcanic art aside from volcanic art what other geologic events could be formed in convergence of oceanic continental crustal plates the continuous grinding of plates against each other will cause the occurrence of earthquakes. One important geological.
Feature form at oceanic crust is a trench or also known as submarine valleys. Ocean trenches are the deepest part of the ocean did you know one of the deepest trench of the world is the philippine trench with a depth of 10 540 meters oceanic oceanic convergent plate boundaries the second type of converging plate boundary involves the sinking of oceanic lithosphere beneath another plate of oceanic lithosphere converging oceanic blades will cause formation of trenches and these trenches will become sources of earthquakes underwater earthquakes especially the stronger ones can generate tsunamis or harbor waves. The leading edge of the subducted plate will eventually reach the metal causing it to melt and turn it into magma.
The molten material will rise to the surface. Creating a volcanic island art parallel to the trench. Did you know the western half of the pacific ring of fire is full of this volcanic island arcs including japan indonesia and philippines many parts of the philippines originated from oceanic oceanic convergence this resulted from the collision of two oceanic plates with one of the plates diving.
Under the other majority of the islands in the philippine archipelago are considered as part of the philippine mobile belt. These islands were formed 65 million years ago at the southern edge of the philippine seaplane and are considered as part of island arcs other parts of the philippines such as palawan mindoro and the zamboanga peninsula. Are all highland sections of the sundalan block of the eurasian plate the philippine mobile belt eventually collided with the sunderland block.

Which explains the presence of trenches such as manila. Necros cotabato trench system. And the solute trench on the eastern side of the philippines trenches like the philippine trench.
And isla zontrough. Are both products of subducting philippine seaplate beneath the archipelago aside from the formation of trenches and troughs chains of active volcanoes that stretches from taiwan to mindoro were created some of the known volcanoes in this chain. Are mount pinatubo and taal also the constant dipping movement of slabs induces frequent moderate to strong earthquakes at various depths gives rise to mountain ranges and develops the geologic character of the philippine archipelago continental continental converging plate boundaries when two continental plates converge a collision zone is formed unlike the other two types of convergent plate boundaries.
Subduction ceases for this type of convergence. What does it mean when we say subduction ceases. It means that no trench.
No volcano and no island arc are created in this type of convergent plate boundary. Instead it leads to the formation of large group of tall mountains called mountain range. Did you know about 40 to 50 million years ago.

Two large land masses india and eurasia collided to begin the formation of the most visible product of plate tectonics. The himalayas also collision of continental plates is associated with shallow earthquake activities. The second part of our lesson on processes that occur along the plate boundaries will be continued in the next video to summarize what you have learned there are three main types of convergent plate boundary.
And these are convergence of oceanic and continental crustal plates convergence of two oceanic crystal plates and converges of two continental crystal plates the convergence of oceanic and continental crystal plates can lead to the occurrence of subduction zone. That gives rise to the formation of volcanic art. Earthquakes and trenches.
The convergence of two oceanic crystal plates can lead also to the occurrence of subduction zone that gives rise to the formation of volcanic island art. Earthquakes and trenches music. If one of the leading edge of an oceanic plate suddenly flicks upward it can generate harbor waves or also known as tsunami.
The convergence of two continental crustal plates differ from the other two types of convergent plate boundary. Because it sees as subduction zone. Which means only mounting ranges and shallow earthquakes are created.
I hope you enjoyed and learned something from our lesson. This is my marian soriano. See you in our next lesson music music music you .
