Convection Current Effects




Asthenosphere Layer 
Plate movements
Part of the lithosphere moves around of the earth caused by movement of the mantle, this create the three types of boundaries Convergent boundaries, Divergent boundaries, and Transform boundaries. Convergent boundaries it’s the boundaries where two plates come together, Divergent boundaries it’s when two plates move away each other and Transform boundaries it’s when two plates slide each other. those are a effects caused by plate movements, visual effects of this boundaries could be subduction zone when the continental crust and oceanic crust come together and the dense crust(oceanic) move under the continental crust another visual effect it's hot plots create volcanos and islands in the continental crust another effects could be the sea floor spreading where the oceanic plates move away through divergent boundaries, a the consequence of this movement create a mid ocean ridge , in the continental crust divergent boundaries create rift valleys and mountains and finally the deep sea threch it’s a big hole between oceanic crust and continental crust under the seas
Lithosphere Layer 
Disaster caused by boundaries
Earthquakes
It’s a strong vibrations through the ground its call to the seismic waves.
Types of wave
S and L waves it’s a curve waves through the earth but L waves its they must dangerous waves. P waves it’s a wave moves around back and forth.
Tsunami
It’s an earthquake or fault under the seas where spread a big waves through the water.
Faults:It’s a big crack through the ground this are three types of faults Normal fault when part of the ground moves down, Reverse fault it’s when part of the ground move up and Transform fault it’s when the ground moves in every places. 
Mantle layer 
Volcanos rift valleys and mountains 





Critical thinking question 
Do you agree with the theory of plate tectonics? 
I total agree with this theory because we can see evidence to prove this theory like convection currents caused the boundaries and through this movements this create mountains, islands ,volcanos faults, earthquakes and Tsunami are clear evidence of this theory  the lithosphere are in constantly movement this make part our life's .


Reflection 
1) What did you enjoy most about this project and why ? 
Well this project that most thing I really enjoy was drawing the mini posters and make the video and the labs
2) What was most challenging for you during this project and why ? 
The most challenging part of this project for me was the volcano model and part of the lab   
3)What new skills did you learn from doing this project ? 
use animoto videos organized my blog and make fordable 
4) Is there anything that you could have done nto improve any of your work ? Explain .
be responsible and  efficient help me to do my work on time and make extra  work and improve my grades
