I agree plate tectonic, because the evidence of the continental and fossils to proof this idea.
The plate tectonic is the theory that earth sections. Earth is made of many different pieces, the convection currents in mantle to cause the land move.
The earth made of 4 layers, the firs layer is called the asthenosphere or the crust, it is the soild part. The second part is called the mantle, where the convection currents take place. it is the liquid part. Third layer is called the outer core, the liquid part. The middle is called the inner core, soild part.
The continental drift is how the continental form. Earth is a big continental before many years, called the Pangea. After many years, it separate through many years it become the continentals now. This theory is thought Alfred Wegener in 1912. it can be trust because the evidence of fossils, rock and puzzle.
The earth has 3 spheres, Atmosphere( air), hydrosphere(water) and lithosphere( rock). we live in the lithosphere.
The continental move by plate boundaries. divergent boundary is when land separate, which create mid- ocean ridge /rift valley/seafloor spreading. The convergent boundary is two land connect together, it create the subduction zone/ mountains. The transform boundary is the plate move side by side, it create the earthquake/ fault/ tsunami.
The volcaneos create by magma shot up. 3 type of volcaneos, shield volcano is made up form thin lava, it has gentle slope. The cinder cone volcaneo is create by magma pressure release cause explode. The hot spot is in the ocean, cause by seafloor spreading.
The fault is a break in the earth crust,cause by transform bounday. The normal fault is the land break goes down. The reverse fault is the land break goes up. The strike-slip fault is thland move opposite direction.
The fault will cause earthquake, earthquake is the separate vibrates. Epicenter is the place the first shake effect by earthquake. the focus is the start point of earthquake in the plate.earthquake cause the seismic waves. P-wave is move front and back. S-wave is move up and down. L-wave is move all the direction. The thing that we use to test the eave is called the magnitude. Tsunami is the earthquake in the ocean.
The mountain is create by convergent boundary. we decide a mountain type according to its shape. The dome is create by magma push up to cause land goes up. The fold mountain is create by magma push land from both side together. The fault block is the earthquake cause cruck goes up and down.Volcanic mountain is the when volcaneo die.
The convergent boundary of oceanic plate and continental plate will cause subduction zone.most density part goes underneath the earth. It create trench, mountain building, and volcainc arc.
Those movement to cause the earth look like now.

REFLECTION
1)what did you enjoy most about this project and why?
I enjoy the activity of this project, because we learn how to create Manual, video
2)what was the most challenging for you during this project and why?
The most challenging is to do the lab, because it has a lot question.
3)what the skills did you learn from doing this project?
I learn how to make a video.
4)Is there anything that you could have done to improve any of your work? explain.
I think i need to add more detail in my work.
5)what would you change about this project?
none, this project is good.

PHOTOGRAPHIC EVIDENCE VIDEO EARTH MOVEMENT
SUMMARY:
The Earth Movement through many thousand years to form the world now. The mountain of Himalayas in India is one of the result of convergent boundary. Convergent boundary is when two plate connect together to goes up become mountains. Another type of convergent is Subduction Zone, this is connect of continental and oceanic crust. The oceanic have most density to goes underneath of the earth. As a result trench. And volcanic Arc also because the magma pressure release to shot up. The Africa valley is cause by divergent boundary, which is two plate separate. When it take place in oceanic, the mid- ocean ridge form. Somerset, UK the break part that we see is called fault. Three main type of fault: Normal fault(land break one goes down), Reverse fault(land break one goes up), and strike-slip fault( land break goes slide each other). The Hawaiian Islands formed as a result of hot spots. Hot spot is when oceanic crust move to cause magma shout up, after it turn cool become the islands. The earthquake and Tsunami in Haiti 2013 is cause by transform boundary, because two plates slide by each other to cause shake in the plate Tsunami is transform boundary in oceanic crust. Where have most earthquake and tsunami happen is called Ring of Fire. The Earth Movement will taking the disasters to our lives, like earthquake and tsunami, but also because of earth movement we have so much beautiful place in our Earth and tourist attractions to travel.
