Evidence Paper

Name: Andy Cheung
Class: K
Subject: Earth Science

The formation of the Earth is a mysterious. However, Earth’s structure is a common knowledge. Plate tectonics is the theory that the outer layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface. The formation of earthquakes and tsunami is related to the Theory of Plate Tectonics. Tectonic plates map draws the general outline where the earthquakes and tsunami occur the most.  

Earthquake is one of the most destructive natural disaster. However, earthquakes are only occur in certain area with certain conditions. The area has to located either in between two tectonic plates or in fault zone. For the tectonic plates, earthquake is caused by transform boundary. When two tectonic plates slide along each other, It releases energy in waves. It also knowns as earthquake. Here is an example of transform boundary earthquake. The strongest and most famous earthquake along the San Andreas fault hit San Francisco in 1906. Many buildings were shaken to pieces by the quake, and much of the rest of the city was destroyed by the fires that followed. More than 600 people died as a result of the earthquake and fires.

On the other hand, earthquake is also caused by sudden slip on a fault. Stresses in the earth's outer layer push the sides of the fault together. When rocks slip suddenly, it releases a energy in waves that travels through the earth’s crust. Here is an example of normal fault earthquake. The earthquake that happened in the New Madrid area along the Mississippi River was a big earthquake in early 1800s. The magnitude of the earthquake ranged from 6.7-8.8. The number of lives lost from the earthquake remains unknown.

Tsunami is another form of earthquake. However, tsunamis are happened in the mid-ocean. Tsunamis are caused landslide. Rockfalls or icefalls landslides can generate displacement of water to create a tsunami. Landslide-induced tsunami is the example of landslide tsunami. It caused by the movement of a significant amount of earth for the construction of an airport, which resulted in destructive tsunami waves hitting the harbor of Thebes.

Seismic waves waves also known as earthquake waves. These waves caused earthquakes and tsunamis. These waves are P wave, S wave and L wave. P wave moves from side to side. S wave moves up and down. L wave moves in all directions. Scientists are used these waves to measure the magnitude(size) of earthquake based on Richter Scale. Seismograph is the tool to measure the magnitude of earthquake.   


In conclusion, the Theory of Plate Tectonics explains the causes of earthquakes and tsunami. The Theory of Plates Tectonics divided the Earth into couple plates. According to the evidence above, earthquakes and tsunami mostly occur between two plates. They are mostly caused by transform boundary. San Francisco is one of the city where earthquakes happen frequently because It is located close between two tectonic plates.

Fault is a movement of rocks break down. It has caused many features and wonders in the Earth. There are 3 major faults. The first fault is normal fault. Normal fault is happened when two blocks of crust pull apart from each other. Tucki Mountain is an example of normal fault. It is located in Death Valley National Park, California. It forms the tectonics boundary between Pacific Plate and the North American Plate. The second fault is reverse fault. Reverse fault is happened when one block of crust slides on top of the other. Sierra Madre is an example of reverse fault. It is located in southern california. It forms the tectonic boundary between the Farallon Plate and the North American Plate. The last fault is strike slip. Strike slip is happened when rocks slide along each other. San Andreas Fault is an example of Strike slip. It is located at California. It forms the tectonic boundary between the Pacific Plate and the North American Plate. In conclusion, fault has a major role in the Earth. It has created different landforms.

ROCK FORMATION
Rock cycle is rock formation from one type to another. There are Igneous Rock, Sedimentary Rock and Metamorphic Rock. In this case, magma is the start point of the rock cycle. Magma is molten rock inside a volcano. After volcano eruption, magma erupts from volcano. It becomes lava. Lava is cooling down for a while. It becomes Igneous Rock. Igneous Rock is weathering from wind and rain. These pieces of rocks is called sediments. During the process of erosion, sediments move to water. After the process of compaction and cementation, sediments hold and squeeze together. It forms Sedimentary Rock. Sedimentary Rock is the bottom layer of the Earth. Sedimentary Rock heats and presses by the top layer. It forms Metamorphic Rock. These rock closes to magma. Therefore, magma melts metamorphic rock.

Reflection
1) What did you enjoy most about this project and why?
I am enjoyed the research because it helped a lot to understand my cycle.

2)What was most challenging for you during this project and why?
The most challenging part is making movie because I had to deal with many issues in this videos. It had to put everything in order.

3) What new skills did you know from doing this project?
I learned to how to imovie to create video.

4) Is there anything that you could have done to improve any of your works?
If I can improve this work. I will take another pictures. As you can see, some of the backgrounds don't match.

Reflection



Reflection: Write a reflection about your Sleep & Learning PSA on your blog

1. How does sleep effect your learning? 
2. How much sleep do you get each night? Do you think this is enough? Do you feel tired in the morning?
3. Will you change what you do after reading about sleep and learning? Why or why not?

1) We are learning while we sleep. Brains practice what we have learned during the day when we are at sleep. 

2)I get 10 hours of sleep on each night. It is above the recommended hours (9.15hours). It is enough time of sleep. I have enough time for my brain to practice what I have learned. I feel energetic in the morning. 

3)I will sleep earlier than I did now because sleeping has positive effect on learning. In addition, teens need more sleep than other ages. Our bodies is growing during this age.

Final Reflection

1) I think energy drink increases energy in a short period of time. In addition, it is good for health. I
     wouldn't hurt my health.

2) NBC News states " Energy drinks are under studied, overused and can be dangerous for children.         Energy drinks contain mostly too much caffeine which cause stroke high blood pressure and even sudden death.  However, the drink makers will actually disagree with NBC News because it has a directly effect on the sale of their products.

3) I will not drink these energy drinks because it contains too much caffeine. It has a negative effect    on health. In addition, energy drinks often don't label the accurate ingredients list. Therefore, I have no idea what I have drink.

China has several natural characteristics of China. In this case, China is in tropical zone. Tropical temperature remains constant throughout the year. It has the annual average rainfall of 2847.3 mm. China has Gobi Desert, Plateau of Tibet and Lion Rock. Flood and earthquake are the major natural disasters in China. China's water sources come from South China Sea, Tai Lake and Hai River. These factors build up our environments, traditions and cultures. Therefore, we are different.



Reflection

1) I enjoy to find the information about China. It helps me to know better about China.
2) The challenging part of this video is when I gather everything into the video because I have to put          everything into a right sequence.
3) I learn how to use a new program, Animoto. It is an interesting way to present thing.
4) I can add my personal pictures into my video. It make the video looks interesting.
5) Everyone should have their own accounts. It prevents the case that happened now. It is more safety     for  everyone.
