Plate
Tectonic
Summary
The theory of plate tectonic is when the earth’s crust is broken into plates sections that pieces moves on top of the liquid mantle asthenosphere.This is also known as Theory of plate Tectonic. The Tectonic plates moves because of the rising and falling Convection Currents. Convection Current of hot and cold fluid going in a circular motion (the movement of the heat under crust as the heat move under crust it force plates to move away from other plates or to come toward it). The causes of the Tectonic plate as the plates move away the new Rift valley and Ridges formed and when the plates move toward each other it create Volcanoes, Mountains. Plates in our planet moves because of the intense in the earth’s core that causes molten rock in the mantle layer to move. This is called the convection currents.
Earth’s Interior
- Lithosphere: Solid part of the Earth
- Hydrosphere: liquid part of the Earth
- Atmosphere: Gases – Air
- Crust: Solid thin outer layer of the Earth (There are two type of crust)
- Oceanic Crust: Crust below the ocean
- Continental Crust: The thick part of the earth’s crust that forms the large land masses
- Mantle: Thick layer of the earth below the cust (Made up of Molten Rock)
- Asthenosphere: The lower layer of the crust
- Density: The amount per unit size
- Inner Core: Solid layer made up of Iron and Nickel (Hottest spot of the Earth)
- Outer Core: Out part of the earth which contain liquid
Summary
Earth has six core from inside to outside it is
surrounded by Thick rocky Mantle and
top with the thin Crust. The
liquid Ocean make up the Hydrosphere. The rocky upper
layer of the earth that makes up the plates is Lithosphere. Above the earth surface is Atmosphere. Earth center is extremely hot its temperature is
same as sun surface it called Inner
core. The liquid part of earth is Outer
core. The Asthenosphere
is the upper layer of the earth’s mantle with convection currents (which the
plates slide).
Faults
The
fractures (a break) in the earth’s crust.
Summary
Faults form when rock is put under so much stress that it can no longer bend but break. Plates slide past one another moving in opposite direction. There are three types of Faults.
Normal:
Rock
move down
Reverse/Thrust:
Rock
move down
Strike slip:
Rock
slide past one another in opposite direction
Plate Tectonic
Summary
The earth’s crust is broken into plates that float
on the part of the Mantle this is also known as Theory of Plate Tectonic. The Tectonic Plates move because of raising and falling Convection Currents in the
mantle it cause the slow movements in the plates. The plates move away from
each other or toward each other.
Critical Thinking Question:
I agree with the theory of plate’s tectonics
that the plates are divided into section (Broken into pieces). Many evidence proved this theory such as Earthquake,
Volcano’s & Mountain’s formation. The movement of these plate’s cause
earthquake and the volcanoes also form when plates move on top of mantle and it
allow magma to come out & and when these broken plate section move toward
each other more dense plate go under and one toward sky creating mountains.
Reflection
1. What did you enjoy most about this project and why?
One thing that I enjoyed was organizing all work for presentation and editing
video (Narrative Video)
2. What was most challenging for you during this project and why?
The most challenging during this project probably time management, because
since we began our internship, we had less time to work on our project at
school, and we was required to finish many thing at home.
3. What new skills did you learn from doing this project?
I learn time management
and it helped me to finish my work on time.
4. Is there anything that you could have done to improve any of your
work? Explain.
Yes there are plenty of things I can
improve such as Presentation and making my project more interesting. I had less
time to finish this project I tried to finish soon as I can so I didn’t want how
I did it because I was running out of time.
