Since we know most about the astronomical objects close to Earth, we will focus on the events leading to the formation of our own Solar System. Any model of these events must explain a number of known facts about our Solar System, namely:#All of the planetary orbits lie in a single ...
【解析】题干问的是：根据第 2 段，下列关于十八世纪太阳系起源理论的说法，哪一个是正确的？根据题干the origin of the solar system定位到段首句：关于太阳系起源的一个关键证据是，所有的行星都在同一个方向和几乎同一个平面上绕太阳公转，对应A选项。
When you drop a ball, the gravitational attraction of Earth makes the ball travel faster and faster as it falls; in the same way, material falling inward toward the protosun would have gained speed.Asthis fast-moving material ran into the protosun, the energy of the collision was converted ...

SOLAR SYSTEM, FORMATIONSUPERNOVAE, GENERALIn the two previous chapters, the density and other physical quantities within the Earth were deduced with considerable precision. Next, we want to know what sort of material is there, i.e. what is the chemical composition of the Earth's interior, ...
By the 1960s, both analysis of meteorites and refinements of solar evolution models converged on an age for the solar system, and hence for Earth, of 4.5 billion years. 12/14 Which of the following can be inferred from paragraph 6 about the formation of the solar system? A The Sun ...
Formation of the Earth Earth is our home, and the only planet known to humankind to support life. Our home is located in our solar system, in the middle of one of the arms of the Milky Way Galaxy. The formation of Earth, along with the formation of the rest of the solar system, ...
This idea was revived by O.Yu.Schmidt in 1944 on the basis of geophysical and geochemical data. Schmidt pointed out that the planetary cosmogony should be based not only on scarce astronomical data about the planetary system but also on the whole evidence from all earth sciences. Though he ...
