魔法麻將少女你們耍百合也要有限度的啊
12集三校都不知道在百合個什麼勁..............
等一下副將戰時鶴賀也會來次百合。。。真是夠了你們！

出於我無聊的個人小興趣才寫的，沒興趣的略過。上次原本想放雲霄飛車的歷史來的忘記了。等下放。

Earth's atmosphere layers

Exosphere 外逸層，外大氣層  特徵：From 500–1,000 km (310–620 mi; 1,600,000–3,300,000 ft) up to 10,000 km (6,200 mi; 33,000,000 ft), contain free-moving particles that may migrate into and out of the magnetosphere or the solar wind.
Exobase aka. critical level , the lower boundary of the exosphere.

Ionosphere 電離層 特徵：The part of the atmosphere that is ionized by solar radiation stretches from 50 to 1,000 km (31 to 620 mi; 160,000 to 3,300,000 ft) and typically overlaps both the exosphere and the thermosphere. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. Because of its charged particles, it has practical importance because it influences, for example, radio propagation on the Earth. It is responsible for auroras.

Thermopause
Thermosphere 熱成層 特徵：From 80–85 km (50–53 mi; 260,000–280,000 ft) to over 640 km (400 mi; 2,100,000 ft), temperature increasing with height. The temperature of this layer can rise to 1,500 °C (2,730 °F). The International Space Station orbits in this layer, between 320 and 380 km (200 and 240 mi).

Mesopause
Mesosphere 中間層 特徵：From the Greek word "μέσος" meaning middle. The mesosphere extends from about 50 km (31 mi; 160,000 ft) to the range of 80–85 km (50–53 mi; 260,000–280,000 ft). Temperature decreases with height, reaching −100 °C (−148.0 °F; 173.1 K) in the upper mesosphere. This is also where most meteors burn up when entering the atmosphere.

Stratopause
Stratosphere 平流層 特徵：From the Latin word "stratus" meaning spreading out. The stratosphere extends from the troposphere's 7–17 km (4.3–11 mi; 23,000–56,000 ft) range to about 51 km (32 mi; 170,000 ft). Temperature increases with height. The stratosphere contains the ozone layer, the part of the Earth's atmosphere which contains relatively high concentrations of ozone. "Relatively high" means a few parts per million—much higher than the concentrations in the lower atmosphere but still small compared to the main components of the atmosphere. It is mainly located in the lower portion of the stratosphere from approximately 15–35 km (9.3–22 mi; 49,000–110,000 ft) above Earth's surface, though the thickness varies seasonally and geographically.

Ozone Layer 臭氧層 特徵：Though part of the Stratosphere, the ozone layer is considered as a layer of the Earth's atmosphere in itself because its physical and chemical composition is far different from the Stratosphere. Ozone (O₃) in the Earth's stratosphere is created by ultraviolet light striking oxygen molecules containing two oxygen atoms (O₂), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken O₂ to create O₃. O₃ is unstable (although, in the stratosphere, long-lived) and when ultraviolet light hits ozone it splits into a molecule of O₂ and an atom of atomic oxygen, a continuing process called the ozone-oxygen cycle. This occurs in the ozone layer, the region from about 10 to 50 km (33,000 to 160,000 ft) above Earth's surface. About 90% of the ozone in our atmosphere is contained in the stratosphere. Ozone concentrations are greatest between about 20 and 40 km (66,000 and 130,000 ft), where they range from about 2 to 8 parts per million.

Tropopause
Troposphere 對流層 特徵：From the Greek word "τρέπω" meaning to turn or change. The troposphere is the lowest layer of the atmosphere; it begins at the surface and extends to between 7 km (23,000 ft) at the poles and 17 km (56,000 ft) at the equator, with some variation due to weather factors. The troposphere has a great deal of vertical mixing because of solar heating at the area. This heating makes air masses less dense so they rise. When an air mass rises, the pressure upon it decreases so it expands, doing work against the opposing pressure of the surrounding air. To do work is to expend energy, so the temperature of the air mass decreases. As the temperature decreases, water vapor in the air mass may condense or solidify, releasing latent heat that further uplifts the air mass. This process determines the maximum rate of decline of temperature with height, called the adiabatic lapse rate. The troposphere contains roughly 80% of the total mass of the atmosphere. Fifty percent of the total mass of the atmosphere is located in the lower 5.6 km (18,000 ft) of the troposphere.

還沒完喔，接下來是海洋的，至於海洋stratification之類的就算了吧。

Aquatic Layers 基本上我的和wikipedia有點不同喔，雖然主要說明基本上都是wiki的。
一般人用的分類是我標綠色斜體的基礎三分法。但是詳細的來說，例如wiki的寫法將Mesopelagic視為Aphotic zone的一部份。。。所以有爭議....

Terminology : Pelagic  (The word pelagic comes from the Greek πέλαγος or pélagos, which means open sea. It can be thought of in terms of an imaginary cylinder or water column that goes from the surface of the sea almost to the bottom, like the diagram on the left. Conditions change as you go deeper down the water column; the pressure increases and there is less light. Depending on the depth, scientists further subdivide the water column, rather like the earth's atmosphere is divided into different layers.)

    Photic  透光層
          Epipelagic  =  Euphotic zone  光合作用帶、透光帶。簡單來說就是一般人見到的海平面那層。
    Mesopelagic (is a pelagic zone extending from 200 m (650 ft.) down to around 1000 m (3280 ft.) below sea level. It is located between the photic epipelagic and the aphotic bathypelagic, where there is no light at all. Although some light penetrates this deep, it is insufficient for photosynthesis. AKA. Disphotic zone 不透光帶）

     Aphotic  無光層

          Bathyalpelagic （這層就是比較一般對不透光層的認識。The bathyal zone or bathypelagic – from Greek βαθύς (bathýs), deep – is the pelagic zone that extends from a depth of 1000 to 4000 meters below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below. The average temperature hovers at about 4 °C (39 °F). Although larger by volume than the euphotic zone, the bathyal zone is less densely populated. Sunlight does not reach this zone, meaning there can be no primary production. It is known as the midnight zone because of this feature. Because of the lack of light, some species do not have eyes, but one of the species that does is the viperfish. Another is the frill shark. Many forms of nekton live in the bathyal zone, such as squid, large whales, and octopuses, but this zone is difficult for fish to live in. Sponges, brachiopods, sea stars, and echinoids are also common in the bathyal zone. The fish in this zone have become very energy efficient since it is especially hard to find nutrients. Many have slow metabolic rates, to conserve energy. The fish here have weak muscles, soft skin and slimy bodies. Animals in the bathyal zone aren't threatened by predators that can see them, so they do not have powerful muscles. There are few plants because of lack of sunlight, as they need sunlight to produce their food through photosynthesis. The bathyal zone holds some of the world's largest whales.）

          Abyssalpelagic  看名字大概也知道是啥

          Hadolpelagic = Hadal zone  海溝妖怪層 ( (Greek for "like Hades," in other words "unseen"), also known as trench zone or Hadopelagic zone, is the delineation for the deepest trenches in the ocean. This zone is found from a depth of around 6,000 meters (20,000 ft) to the bottom of the ocean.)
