托福阅读真题第216篇OriginoftheSolarSystem(答案文章最后) Origin of the Solar System Paragraph 1:The orderly nature of our solar system leads most astronomers to conclude that the planets formed at essentially the same time and from the same primordial (original) material as the Sun. This material...
1. According to paragraph 1, which of the following best describes the “nebular hypothesis”? O Our solar system formed from a large cloud consisting mostly of hydrogen and helium and of small amounts of other elements. O Our solar system formed from gases and heavier elements thrown off by...
Around the protostar, a large flat discof dust, rock, and ice, which would become the planets, moons, and asteroids in the solar system, collected.This initial stage in the formation of the solar system lasted approximately 100,000 years. Next,the planets formed through the process known as...
AThe solar system formed from a cloud of gas and dust. BThe solar nebula was massive compared to today's Sun. CThe planets formed from the less-dense parts of the solar nebula. DThe rotation of the solar nebula forced most of its mass to its outer edges. ...
(original) material as the Sun. This material formed a vast cloud of dust and gases called a nebula. The nebular hypothesis suggests that all bodies of the solar system formed from an enormous nebular cloud consisting mostly of hydrogen and helium as well as a small percent of all the ...
O Our solar system formed from a large cloud consisting mostly of hydrogen and helium and of small amounts of other elements. O Our solar system formed from gases and heavier elements thrown off by the Sun as it rotated in the center of the nebular cloud. ...

In this essay, we will discuss the two prevailing theories regarding the origin of the solar system: the nebular theory and the capture theory. The first and most widely accepted theory is the nebular theory, which suggests that our solar system formed from a rotating cloud of gas and dust ...
The solar system includes the Sun, planets, dwarf planets, moons, rings, asteroids, comets, and particles of dust.
