I believe it is the outer crust but i will do more reaserch for you :)
Answer:
The F u k u s h i m a nuclear accident gave ''wind in the back'' to the opponents of the production of nuclear energy because of the dangers from it.
Explanation:
Nuclear energy is produced via nuclear reactors. They are very expensive to be constructed and maintained, but the expenses are balanced very quickly because the nuclear reactors produce much more energy than any other type of facility for this purpose. It is also the cleanest and most environmentally friendly from any major type of production of energy.
Unfortunately, the production of nuclear energy doesn't come without risks. Even though very rare, accidents do happen, and when they do they cause much more damage than any other facilities for the production of energy. A more recent example is the accident in F u k u s h i m a, Japan, which resulted in a large-scale movement of people out of the area, abandoning of everything in the surroundings, and the area will not be suitable for usage for a very, very long time because of the very high levels of radiation. The opponents of nuclear energy production used this accident to make a point, especially cause it was one that happened in one of the most advanced countries, and what kind of consequences it had there, let alone if it happened in other parts of the world.

2. Newton.
3. Kepler.
4. Brahe.
5. Refracting telescope.
6. Reflecting telescope.
7. Astrolabe
8. Camera.
9. Radio telescope.
Explanation:
1. Galileo: he discovered details of a lunar surface.
2. Newton: he invented first reflecting telescope.
3. Kepler: he found planets had elliptical orbits.
4. Brahe: he performed a systematic mapping of sky.
5. Refracting telescope: uses a large glass lens.
6. Reflecting telescope: uses a mirror to focus light.
7. Astrolabe: tool used to determine location of a star.
8. Camera: instrument that accumulates light from an object to show more detail.
9. Radio telescope: records sounds of stars.
Answer:
The spectral types and sub-classes represent a temperature sequence, from hotter (O stars) to cooler (M stars), and from hotter (subclass 0) to cooler (subclass 9). The temperature defines the star's "color" and surface brightness. ... Stars are also classified by luminosity class.
