In Simpson's (Simpson, G.C. [1927]. Mem. R. Meteorol. Soc. II (16), 69–95) classical derivation of the temperature of the Earth in the semi-gray model, the surface temperature diverges as the fourth root of the thermal radiation's optical depth. No resolution to this apparent parad...
We introduce a novel Earth-like planet surface temperature model (ESTM) for habitability studies based on the spatial-temporal distribution of planetary surface temperatures. The ESTM adopts a surface Energy Balance Model complemented by: radiative-convective atmospheric column calculations, a set of ...
relatively small size选项对应第三段第二句，应该属于类地行星的； contain选项对应第四段最后一句，属于类木行星的；temperatures选项对应第五段第三句，温度越高，逃逸速度越小，聚集气体的能力越差，所以应该属于类地行星的；density选项有一定迷惑性，原文第四段说类地行星密度大类木行星密度小，说的是类木行星...
Earth is the third planet from the Sun, and so far is the only planet that we know of that is capable of supporting life. The average surface temperature here is about 14 °C, but it varies due to a number of factors. For one, our world’s axis is tilted, which means that one h...
Inner planets are the four planets closest to the Sun: Mercury, Venus, Earth and Mars. They are collectively characterized by a solid surface and small size relative to the outer gas giants. Featured Moon experienced more large impacts than we currently see on its surface ...
model to simulate Earth's climate at obliquities up to 90°. We show that Earth's climate would become regionally severe in such circumstances, with large seasonal cycles and accompanying temperature extremes on middle- and high-latitude continents which might be damaging to many forms of life....
Both the very high surface temperature and massive atmosphere of Venus may be the result of the solar flux being a factor of two higher at its orbit than at the Earth's orbit. This difference may have led to a runaway greenhouse effect on Venus, i.e., the emplacement of volatiles ...
The Earth has been formed by a huge mini-planet collision forming our Earth surface and our Moon today. Such a central collision hit was statistically rare. A much probable skimming or nearby encounter by other moons or planets had to occur. Indeed Recent observations suggest that many planetary...
阅读理解AThe earth is the only planet that scientists think haslife. Why does the earth have life while the other planets(行星) don't? For one thing, the earth has just the rightemperature. As the third planet from the sun, the earthseems to be just the right distance away. The plane...
