What is the best description of the origin of the solar system?
Would it have been possible for a large, Jupiter-like planet to form in the location of Mars?
In the early stages of the solar system's formation, a protoplanetary disk of gas and dust surrounded the young Sun. Within this disk, planets began to form through a process called accretion, where small particles collided and stuck together, gradually growing in size.
The location of a planet's formation is influenced by various factors, including the amount of material available and the temperature gradient in the protoplanetary disk. Jupiter, being a gas giant, formed further out from the Sun where the disk was cooler and contained more volatile elements.
On the other hand, Mars is a terrestrial planet and formed closer to the Sun where the disk was warmer and contained primarily rocky material.
Therefore, it would not have been possible for a Jupiter-like planet to form in the location of Mars due to the differences in the composition and conditions of the protoplanetary disk in those regions.
Which of the following observations does NOT provide information about the formation of the solar system?
Among the provided options, the observation that "most of the planets orbit the Sun in the same plano" does not provide information about the formation of the solar system.
While it is a characteristic of the planetary orbits, it does not directly contribute to our understanding of how the solar system formed.
Other observations mentioned in the options, such as the distances of Jovian planets from the Sun, the direction of planetary orbits, and the rotation of planets on their axes, provide valuable insights into the formation and dynamics of the solar system.
What statement best describes the origin of the solar system?
The best description of the origin of the solar system is that "the solar system formed from the collapse of a spinning cloud." This statement refers to the nebular hypothesis, which suggests that the solar system originated from a rotating cloud of gas and dust known as the solar nebula.
Over time, the gravitational collapse of the nebula led to the formation of the Sun at its center, while the remaining material in the disk-shaped cloud coalesced to form the planets, moons, asteroids, and other celestial bodies within the solar system.
This hypothesis is supported by various lines of evidence, including observations of other star-forming regions and the composition and characteristics of the solar system objects.
