Shaking Our World of Plate Tectonics

Summary of Earthquakes, Volcanoes, Faults, Earth's interior, plate tectonic and Plate Boundaries


Earthquakes is a sudden shaking of the earth's surface that often causes a lot of damage. When earthquakes happen will be caused by many people of the injury. Earthquakes are has fast and slow, has P- waves , S- waves and L- waves. but P- waves is move faster. S- waves is move slowly, also quakes are measured and recorded using a machine call a seismographvolcanoes an opening in the earth that islands erupts gases, ash and lava. it escapes from below the surface. A volcanic eruption occurs, magma that has erupted is called lava. The plates are all moving in different directing and at different speeds. The theory explains why earthquakes and volcanoes are likely to occur in particular locations and how new crust forms along the ocean floor. Faults are surfaces along which rocks have fractured and been displaced, there are there major tectonic plate movement caused by pressure over time, eventually leading to a break in the Earth's crust along the rocks.
The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron and is so hot that the outer core is molten. Lithosphere is solid part of the earth.
There has different types of plate boundaries, between plates, volcanoes, earthquakes, mountains and trenches are all results of movement along plate boundaries. The Convergent Boundary is two plates that come together, to become oceanic and continental plate to create a mountain. Subduction Zone is when
1 plate goes under author plate, it is happening to volcanoes oceanic. The Divergent Boundary is mantle moves the plates is created by liquid rock pushing up from the mantle. Transform boundary are plates slide past each other and cause friction. Fault Zone is large fractures a break in the earth's crust to effect earthquakes. Earthquake effects damage to towns ad cities, Tsunami caused by an under water earthquake. Hot spot is unusually hot areas of the mantle core boundary effects volcanoes.

Do you agree with the theory of plate tectonics? Why or why not?
yes, I agree because the theory of plate tectonic say that earth's crust is broken up into pieces called plates, also is explain the continental drift theory and explain Earth's lithosphere is put together by the plate. The Earth;s internal structure of the outer most layer is divide into two parts, the outer layer of the lithosphere and the inner asthenoshpere. Therefore, Scientists have found seven major plates put in together.



Reflection
1. What did you enjoy most about this project and why?
I was enjoy about the video because I can put any song I like put in the I make the video.

2. What was most challenging for you during this project and why?
I most challenging about each topic should be take the test, because it is most difficult for me, I need learned more.

3. What new skills did you learn form doing this project?
I learn a lot information about plate this topic

4. Is there anything that you could have done to improve any of your work? Explain.
I think I need to improve the prediction map for the plate boundaries, because there was a lot information and evidence I don't understand need to learn more.
