 Epicenter and focues is a visual   effects in the surface







Seismic
in the lithophere exist three types of seismic waves

L wave
the L waves and S wave its a curve wave

L wave

S wave



P wave
its a wave with follow the same direction




A earthquake could be happend in anywhere include under the water the earthquake its called Tsunami

Tsunami






Volcanos

the volcano its a elevation of the plates movements diverge boundaties create most of the volcanos, in the lithophere exist three types of volcanos composite volcano, cinder volcano and shiled volcano. inside the volcano the liquid rock its called magna and outside the volcano the liquid rock its called lava

Shield volcano

shield volcano its a big type of volcano exist in the lithophre, this volcano have may frament of lava inside and when this volcano erupt cancreate a island like is hawaii



Composite volcano

its a medium volcano can erupt too but this volcano have some framents of lava inside

its a smaller volcano of the lithophere some of this volcanos do not have lava inside

Rotation and Revolution 



Vocabulary words
Rotation (rotacion): its when the earth
move around the axis
Revolution (revolucion de la tierra ): its when the earth move around the sun
Earth axis ( ejes de la tierra ) : imaginary line through the earth
Tilt ( inclinacion): not straight 23.5 degrees
Times zones ( horario o hora mundial ) :the counries have different times  by hours
Eliipse (orbita): shape of the orbit around the sun
Seasons ( estaciones ): caused by the earth revolution the earth have 4 diifferent types of climate called seasons : winter,summer,fall and spring .

Rotation


Rotation and Revolution

In the heilocentric model is the theory to support the idea abouth the sun its a center of the universe. rotation and revoltuion it's a important evidence  we can see about this cosmo model. Revolution  Is the time period the earth take to move aroud the sun during 365 days the earth always points the polarys star  the effects during the earth revolutions it's the seasons is a change of the climate, 4 seansons such are winter, fall, summer and spring ,the earth are divided by two hemispheres; north and sourth.  during of change of season every country have different time like if  in colombia its 9 pm in china its 4 am that called times zones. Rotation is when the earth move himself during 24 hours evidence of this process it's day and night .

how is earth affeted by movement (revolution) ?
the effects of the earth revoluttion in the earth is though the season the change of the climate
winter, summer, fall and spring , the tides in the earth the water levels and the phaces of the moon all this process its dependent of the revolution and rotation and also affected the life of organisms  in the earth .

Reflection:

What did you enjoy most about this project and why ?

I like this project , I think was funny learn about the earth in this way and share with my classmates.

What was most challeging for you during this project and why?

I think the most more challenging part was when my group must to prepare and practices forthe video will be ok but practices and draw the project by myself was a difficult.... but fine .

What new skills did you learn from doing this project?

besides to learn all about rotation, revolution, tides,seasons and everything I learn also to make more funny pictures inthe project and be more creative .

Is there anything that you could done to improve any of you work ? explain

Well its important when you work in a group to finish of the stuff on time and be clear , but I think the this project help to improve to do be more creative and original .
