Critical Thinking Question
Have you ever heard
about the theory of plate tectonics? Have you ever asked yourself what is it?
Is it important or not? Does it relate to our real life or is it just history?
The theory tectonics is the theory that tough
external layer of the Earth (the lithosphere) is divided into a couple of
plates. There are two kinds of crust, the oceanic and continental. Oceanic
crust is 5-10 km thick and 32-70 km for the continental. This thickness moves 3
inches per year. Convection currents are really important for this theory,
because it’s the movement of earth’s plates. Convection Currents moves the
crust of the earth. I agree with theory of plate tectonic because scientists
prove its right and all the natural disaster occurs because of the movement of
the earth crust.
Convection currents are
one evidence that scientist use to prove the movement of earth. Convection current
occurs in the mantle part of earth. The earth has four main layers. The outside
layer is called crust, which is where the two of earth plate, oceanic and
continental crust. Then the mantle, and it made of melted rock, it’s liquid
layer, and that’s where the convection currents occurs. Then, the outer core
and last the inner core. The hottest layer is the inner core. Convection
currents cause the movement of the crust. Convection currents process plays an
important rule to the movement of earth. Convection current moves the plate
slowly per year. Hot spot also prove the movement of earth. Hot spot is a place
where volcanoes are still active. For instance, Hawaii is an example of hot
spot place. Hawaii is in danger because their s a lot hot spot and volcanoes
may happen.
Continental drift also
used to prove the movement of earth. Continental drift theory is a theory that
Alfred Wegener thought about the Pangaea and that continent were together.
Pangaea was formed 300 million years ago, which broke up 250 million years ago.
Some evidence of the theory is fossils, rocks record, and mountain ranges. I
think this theory is agreeable because it show and prove the movement of earth.
Himalayan Mountain in China proves the movement of earth. Earth movement may be
dangerous because it may cause real and serious natural disaster such as
volcanoes, tsunami, mid-ocean ridges, rift valley, and more.
Plate boundaries are also
one of the evidence that prove that earth’s plates are moving. The three kinds
of boundaries are convergent boundary; it’s when two plates come toward each
other creating mountain and trenches. Divergent boundary is when two plates
pull apart from each other and mid-ocean ridges and rift valley is formed.
Finally, transform boundary, when two plates slide each other causing
earthquakes and tsunami. Earthquakes are also caused by faults, a crack in the
earth. Also subduction zone can cause trenches and volcanoes and it’s when
oceanic plate and continental plate comes together.
Scientist proves that earth’s
plates always move. The plate moves so slowly, it moves 3 inches per year. The
mantle part of earth is made up of melted rocks. Mountain building is also
example of earth’s plate movement. Plate Tectonic the curst layer on the land,
it has many effected the continent to move, when the milted rock goes up the
heat probably force the plate to move which called convection currents, a lot
of people ask about how does volcano happened, and tectonic plate has part of
causing that when the two land divergent from each other the heat begins to
lose and as it goes down like circle the subduction zone grate. I agree with
the theory because the world is facing a lot of earthquake and hurricane and
other natural disaster. I believe the earth’s plate move because of earthquake
and the shaking of the earth. The theory of plate tectonic claims that the
structure of earth’s crust shows us that the earth moves since 300 million
years ago. In the beginning of the earth were together in shape of Pangaea but
with time it moves. This shows us that earth’s plate had been moving all the
time.
Reflection About The Project
1) What did you enjoy most about
this project? Why?
The most things I enjoyed is doing
different topic and different lessons in a different ways, we do each project
in a different way such as, foldable, mini poster, videos, etc.
2) What was most challenging for you
during this project? Why?
The most difficult part of this project is
that I had to do 5 projects in a current time, so the time management was
a little challenging.
3) What new skills did you learn from doing this project?
During this project I learn a lot of new
skills, some skills I learn is making new video in a website. Before this
project, I always wanted to do video but I did not know any website or anything
but after doing this project, Ms.Kara teaches me the Animato.com, Imovie, and
etc.
4) Is there anything that you could have done to improve any of
your work?
I think if I have the chance to make this
project again, I would take my time making the project look better and to make
the work more thoughtful and using critical thinking strategies.
5) What would you change about this project?
If I have the opportunity to change
anything about this project, I would give more time in class to work on it and
to represent in front of the class.
