Plate tectonics project

Critical thinking question
　　Plate tectonics is the theory than found out by Alfred Wegener, he say than all the Continental is together in one, and call it Pangaea. There is three evidence can prove it. They are fossil, puzzle and mantle.    

　　If we look at the world map, we can see seven Continent is like piece of puzzle. If we try to put it together, it will be work and we can see some Continent is match with other Continent, they both have same natural resource and geography.
　　
　　Geographer found out many fossil in the world. The important thing is the found out same fossil in different continent. It means that those fossil are live in same place and prove that Alfred Wegener theory is true.
　　
　　The last reason is mantle. Mantle is in under the crust, mantle risk when it reach the outer cone, because it is hot so it risk up. When it reach to the top it will fall down because the crust is cold. So mantle is like a wheel than makes crust to move, it explain why the continent is moving.
　　
　　 I agree what Alfred Wegener’s theory. Because it prove by those three evidence and it explain why geographer found out fossil in different continent.
　　
Reflection

　　I enjoy the most in this project is we can chose the stage, because we can chose the one we like to do. The most challenging part is that we must quiz on it, because we need to expert on it. The new skill I learn in this project is work together is easy than work by one. I can improve my by take more time to do in home because it is not enough time in class. I will like to change the quiz because it take a lot of time.

Rock Types

1.Rock cycle- rock cycle is the endless change of rocks and magma. First the magma get cool in the outside of volcanic, the lava get cold down and become igneous rock. Cool inside the volcanic is call intrusive rock, the outside is call extrusive rock. When the wind and waves keep and keep hit the igneous rock, this process is call erosion and weathering. This process keep and keep doing, igneous rock will broke into sediment and sediments cement together is call sedimentary rock. When the sedimentary rock get heat and pressure, it will become metamorphic rock. When metamorphic get heat again, it will become magma again.

2.Rocks-vocabulary
Metamorphic rock-Rock change by pressure and heat.

Magma/lava- molten rock found inside the volcano.

Solidification- magma became solid by cooling.

Igneous rock- magma get cool down.

Weathiering-breaking rock into pieces.

Erosion-pieces rock get transported.

Sediment- sand.

Compaction-compress

Cementation-combine.

sedimentary rock- many sand combine together.

3.Rock types
igneous intrusive- cool inside the volcano with big crystals.

igneous extrusive- cool outside the volcano with small crystals.

sedimentary/clastic-dirty rock.

sedimentary/crystalline-formed under water.

sedimentary/bioclastic- form dead animal and plant.

metamorphic/foliated-with layer in the surface.

metamorphic/non-foliated -with no layer in the surface.

Crystals & Minerals

1.crystals

In the Crystal Growth Lab, we learned how mineral become crystals. We learned how minerals evaporating and crystallized. We also learned the properites of the mineral, like cleavage and fracture. 
   
2.mineral properties
Metallic luster: the mineral looks like metal.

Non-metallic luster: the mineral not looks like metal.  

Color: what the rock is likes like.

Streak: a color form mineral powdered.

Hardness: how hard the mineral is.

Cleavage: a mineral that breaks evenly.

Fracture: a mineral that breaks not evenly.

Composition: what the rock is contain.

3.Mineral identification

BIoitte mica

Color: black to dark brown

Nonmetallic luster: Not looks like metal.

Fracture: breaks unevenly

Hardness: 2.5-3

Steak: white

Composition: Basic fluoro potassium, magnesium, iron aluminum silicate

Quartz

Color:Colorless or variable

Nonmetallic luster: Not looks like metal.

Cleavage: breaks evenly

Hardness: 7

Steak: white

Composition:SiO2
