Convergent Plate Boundaries

1. An oceanic plate is a tectonic plate mainly underneath the ocean, and a continental plate is a tectonic plate mainly underneath a continent,

1.1. What are oceanic plates?

2. Group 10 - Aiman, Nabil, Yulin, Yi Qing

2.1. sorry for no slideshow cause its self service

3. Oceanic plates are heavier and thinner, so they are generally forced underneath the lighter, thicker continental plates

3.1. cold oceanic crust is forced down under the edge of a continental plate, it is heated by the underlying hot mantle. The heating is hastened by friction as the plates move against each other, causing earthquakes.

3.1.1. how does it happen ( referring to oceanic plates)

4. the oceanic plates go beneath the continental plates, the sediments are dragged down to the mantle where they are heated. They melt to create a new kind of magma that forms rocks called andesite

4.1. idk who wrote that <--- so yeaa

4.2. extra knowledge : Andesitic magma often escapes through cracks to the surface, causing volcanic eruptions. The melting sediments contain a lot of cold seawater, so these eruptions can be very dangerous. They are often associated with the release of superheated steam and other gases that can cause violent explosions.

5. What is convergent plate?

5.1. In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide

6. how does convergent plate work?

6.1. Convergent plate moves towards each other and become folded and subducted.

6.1.1. Just a FACT : volcanoes are commonly found near the subduction zone and as well as earth quakes due to the pressure and friction.

7. Definitions for difficult words

7.1. Trench: A long, steep-sided valley on the ocean floor.

7.1.1. volcano: im sure you know what it is by now :)

7.1.1.1. volcano

7.1.2. mariana trenc location

7.1.2.1. a trench looks like
