Tsunami

Word	Native language	Definition
Tsunami	海啸	Tsu meaning harbor, and name meaning wave. Tsunami is a harbor wave.
Subduction zone	俯冲带	When oceanic and continental crash, the heavier one, which is oceanic plate go down.
Continental plate	陆地板块	Its a land top of the water.
Oceanic plate	海洋板块	Its a land under water.

Tsunami happens when there’s a violent disturbance deep below the ocean surface, like earthquake and volcanic eruption. Zone that two plate crash is a subduction zone. When oceanic plate and continental plate crash, the heavier oceanic plate slips under the lighter continental one and cause an earthquake.Tsunami is a series of water waves caused by the displacement of a large volume of a body of water.Tsunami waves move a lot of water and carry a lot of energy, so they can travel long distances.

1. Why does tsunami happen? Tsunami happens when there’s a violent disturbance deep below the ocean surface, like an earthquake or volcanic eruption.

2. What happen when oceanic and continental plate crash? The heavier oceanic plate slips under the lighter continental.

3. What create when oceanic and continental plate crash? It create mountains, trench, and volcanoes

4. What is tsunami? Tsunami is a harbor wave.

5. What create tsunami? A tsunami is usually caused by a powerful earthquake under the ocean floor.

Plate Tectonics

Word	Native Language	Definition
Plate Tectonics	板块构造	Sections of crusts
Pangaea	盘古	All lands together
Outer mantle	外地幔	Plates float around on a layer of molten rock called outer mantle.
Continental drift	大陆漂移	Continents moving apart slowly.
Boundary	边界	Between two plates.
Divergent Boundaries	分散	When two plates move away from each other.
Convergent Boundaries	会聚	When two plates come together.
Transform Boundaries	转换	Two plates move side by side.

Long time ago, the world is one big continent, which is Pangaea.  Tectonic plate, these 

plates float around on a layer of molten rock called outer mantle. As time went by, the 

continents are moving away from each other, which is continental drift. When the plates 

are moving, will occur different type of boundaries. Between two plates is boundary. 

Divergent boundaries are where plates are moving apart. Convergent boundaries are 

where plates are moving toward each other. Sometimes one plate will go under another 

and create mountains. Transform boundaries are two plates move side by side. 

1. What happen when two continental crust come together?  When two continent crash, the heavier one go under another.
2. What are three type of boundaries? Divergent boundaries, convergent boundaries, and transform boundaries.
3. What is the different between divergent and convergent boundaries? Divergent boundaries is two plates move away from each other, convergent boundaries is two plates come together.
4. What is Pangaea? Pangaea is a big continent, all the lands are together.
5.  What's create when two continent crash? Mountains.
