02 Ｏｃｔｏｂｅｒ, Comments and Questions

1. I haven't recognized people as environment, but after listening the lecture, I understand the definition. In Japanese, there is only on word for environment. However, there are few ways to interpret.
2. 資料を見る限りでは，巨大大陸は時間がたつにつれて細分化されているが，なぜ合体することなく分割される一方だったんですか．
3. The story of the earth is big scale. You mentioned the deepest drill record is 12 km. So, I wonder how scientists could understand the earth's structure.
4. I learned that the earthquake are happened between hard areas but if the Earth would be made by only mantle not hard areas, do earthquakes happen? I think earthquakes may not happen, but people can't build buildings if the Earth would be made by only mantle.
5. I understand the earthquakes happen on the plate, but how the earthquakes happened at the places where it were not on the plate?
6. I want to know how fast each plates move.
7. I heard the meaning of "Dynamics" for the first time in this class, and I understood that "Dynamics" is related to the Earth's great evolution or movement.
8. I studied basic earth science in high school, but learning it in English is fresh for me, and it is interesting.
9. It's my first time to see the material of the Earth. There are different colors. I think it' amazing.
10. The crust where is hard can have the earthquakes the mantle.
11. I have had an image that core is very hard. But I learned outer core is liquid. I'm surprised.
12. In Japan, natural disasters happen frequently. So we Japanese often worry about that. But are the ways of thinking against natural disasters different between us and people who live in the area where is no natural disasters?
13. Thank you for your class. In fact, content of this class is different from my major, but it's good opportunity to learn new things. I enjoy taking this class.
14. マントルの外側がhardで地殻もhardならば，マントルと地殻の違いはどう決めたのか疑問に思った．

09 October, Comments and Questions

1. The squeezing between plates can cause volcanic eruptions and the earthquakes, so when do the volcanic eruptions happen and when do the earthquakes happen, what are the difference.
2. Thank you for using my drawing.
3. Last week, I had come to the cause and submitted this paper (without punching student card), and I just registed this course after last week's course, so I want to know if last time will be a absent and if it will impact the final score.
4. Thank you for good lecture!
5. I want to make it sure that Pangaea seemed to be diversing, however, on the opposite side of the earth, it's approaching. Is it right?
6. When mountains are made, does the plate move like or?
7. 津波が発生する地震と，しない地震とでは何が違うのか疑問に思いました．
8. In today's class, I know the contin can move on the seafloor and two types of tectonic plate. I think the cars example is easily for me to understand.
9. You mentioned that Pacific plate and Phil. plate slightly move per year, so someday do continents be bonded again? I agree with your opinion that geology is related with every fields because natural disasters are no longer problems which everyone should think about.
10. You said like this "Foreigners can enjoy earthquakes in Japan". However, I think that remark is rude to people who died because of disasters.
11. I understand why only continents flow but oceanic plates stay.
12. So continental tectonic plate means lithosphere? And you said lithosphere is hard, but oceanic plates are sinking into asthenosphere, so isn't it "really" hard?
13. I love the example of chocolate and biscuits. It was easy to understand.
14. When I was in high school, I didn't understand why oceanic plates sink into under the continent plate, but now I understand by seeing the example of water, paper, and the light thing.

23 October, Comments and Questions

1. Thanks to your drawing. I can understand easier. Thank you.
2. Plate motion will be more faster? You said the plate which have already more inside asthenosphere is faster. This means "Yes" or may question?
3. I know how the ocean shaped for the first time, and I have a question. Why the ocean could be on magma? I think the water (rain) is dewatered before it reaches to the ground.
4. Is the theory that the moon came from Earth officially accepted?
5. プレ−トが移動しているならば，移動している方の反対側にはその内すき間ができるのでは？
6. I learned the history of Earth and the most interesting thing I think is moon is a part of the Earth.
7. The figures you drew were easy to understand.
8. I can understand why tectonic plates move on the asthenosphere.
9. Why does not the African Plate move?

11. Sorry teacher, it's difficult for me to read the English you wrote. Could you write more clearly?
12. Thanks to your drawing, I can understand something quickly by seeing the draw.
13. Whether the Tohoku Earthquake is related to the collision of the Asia-Pacific Plate.
14. My hometown will be affected by Nankai Earthquake, so I hope the system for earthquake prediction develop better than it is now.

Comments and Questions (20 Nov. '19)

1. 日本海での津波は実際に地震から来る波と中国の大陸からの反射の波で，高い波が来るということだが，能登半島から反射した波が中国へ到達して波を高くすることはないのですか？(The tsunamis in the Sea of Japan are a combination of actual waves from the epicentre and a wave reflected from the continent of China, thus high waves will arrive. However, waves reflected from the Noto Peninsula will reach China and make it higher isn't it?)
2. ニュースなどを見ていると，ある地域ではひんぱんに火山の噴火が起きているようですが，そのような地域でも暮らしていけるのでしょうか．(Looking at the news, it seems that there are frequent volcanic eruptions in certain areas. Can local people manage their life in such areas?)
3. 日本海で起こる津波は反射や屈折のため複雑になるということでしたが，能登半島のようにとび出ている地形よりも富山湾のような入り込んだ地形のほうが被害は大きくなりやすいですか．(The tsunamis that occur in the Sea of Japan are complicated because of reflections and refractions. Is the damage high to occur in the bay areas such as Toyama Bay than the peninsula areas such as the Noto Peninsula?)
