Plate tectonic 

      The earth is made up of plates and in the pass million years all the continental land stay together call Pangaea, when the time go on broken into peace and those peace move call 
plate tectonic theory. I agree with this theory accourding to the Theory of continental drift Is discovered  by AlfredWegener in 1915. After discovering the idea of tectonic plates. Through this discovery he perfected an image of Pangaea when the worlds tectonic plates had not moved use the same species animal to compare which land are together in the pass million years.
There were 3 boundaries during the plate tectonic move: convergent boundaries, Transform 
boundaries and divergent boundaries, it cause many many effect to the world.

    

Evidence one if the plate tectonic never move, can’t cause the Convergent boundaries 
which mean when two plate come together, force the mountain, trenches, earthquake and volcanoes. most of the earthquake and volcano happen in the north overriding plate/ sub 
ducting plate, because most of overriding plate is in the north so the most earthquake 
and volcano happen in the north. Few of the earthquakes and volcano happen in the south. The Ring of Fire is an area located under the surface of the Pacific Ocean. As it surrounds a tectonic plate it is prone to frequent earthquakes, as well as volcanic activity. As about 75%
 of the volcanoes are located within that area,  In many countaries the earthquake 
ususally happen because the convergent boundaries it create the seismic wave during the earthquake.

Evidence two if the plate tectonic never move there should be no earthquake and tsunami in the world, but in the 2013 the Hurricane candy was coming is fall the cafiteria in
 International hight school at Lafayette .it cause by the transform boundaries slide each 
other.

 Evidence three if the plate tectonic never mover there should be no seafloor separating and rift valley is cause by convection currents happen in the mantle ,it heating the hot heat up force divergent boundaries, two plate tectonic separate.

 i agree with the theory of continental drift in the pass million years all the land stay to gether when the time go on all the land move cause by transform, divergent and convergent, 
they star move in to peace with those boundaries movement and force many natural 
environment.

  Reflection:

1: i joy the movie most in this project because is very nice showing in the film when the 
student present.

2: the most challenging in this project was doing the lab by label the map it so hard to
 label.

3: i learn a lot in this project about the tectonic movement.

4; i want to improve my presentation make more insteresting and with using the model.

5:the one thing change in the project is i want to to the film is more great then the 
mini-poster.

    

lunar revolutions

                          lunar revolutions

月球革命  Lunar revolution-moon movement around the earth.
月球革命长度 Lunar revolution length- the orbit length by the moon around 27days per one time.
月相 Phases of the moon- the step of the moon change waning to waxing.
月全食total lunar eclipse- the sun and moon at same orbit cause moon cover the sun.
半影penumbra- an area with light shadow during the total lunar revolutions
本影umbra- an outside area with the dark shadow during the total lunar revolutions.

 summary:
    at the center of universe the moon keeping change the size by the movement of
the earth.which call:LUNAR REVOLUTION" the moon depend on its position to the sun and earth, the reason why we only see part of moon because surface at different angle. call:PHASE OF THE MOON" it takes 27 days around the earth per one time, which mean lunar revolution length. moon are change the type of the size during the phase of the moon, from the waxing(moon getting bigger)to waning(moon getting smaller).when the total lunar eclipse happen the sun and moon at the same orbit cause moon cover the sun. during total lunar eclipse, there are two parts of the shadow-umbra and penumbra,the umbra is the darkest part of the shadow at the center.the penumbra is the lighter part of the shadow on the outside.


 how is earth affected by movement.
   when the earth star rotation at the orbit cause we have four season. orbit just like the shape of oval. when the earth is close to the sun, we getting summer,when is faraway from the sun we getting winter.


  what did you enjoy most about this project and why?
   i'm enjoy with the topic is interesting to know how the moon getting bigger and smaller cause by the rotation.

 Science is fun.
 i like sleep.
 light less is scare me.
McDoland is my favorite food.
i will be an makeup when i grow up.
 i have 1 siblings.
 my favorite color is any light color.
my favorite thing to do is sleep.
watch out of playground.
i wish my English well.
