Which of the following describes a role of gravity, in the information of our solar system?

Question

One-in the early stages of a solar system formation a fragment of an ender cloud of dust and gas collapse, and began rotating under the influence of gravity
2-the eight planets were originally orbiting a nearby star in the Sun of gravity, pulled those planets into orbit around the sun
3-gravity causes small particles in the rotating cellar new Luca to stick together and form larger particles. This process repeated itself, forming larger and larger particles that eventually became planets.
4-the combined gravity of the planets, pulls the sun away from a nearby star cluster into the center of the solar system
A.) 1, 2,and4 only
B.) 1,2,3,and4
C.) 1and 3 only
D.) 1,2,and 3 only

Answer 1

The correct answer is C.) 1 and 3 only.

Here's the reasoning for each statement:

1. True: In the early stages of solar system formation, a fragment of a molecular cloud (or nebula) collapsed under its own gravity, leading to rotation and eventually forming a protostar at the center (the Sun).

2. False: The eight planets did not originally orbit a nearby star; they formed from the same protoplanetary disk around the Sun and did not come from another star system.

3. True: Gravity plays a crucial role in the process of accretion, where small particles collide and stick together, forming larger particles and eventually leading to the formation of planets.

4. False: The Sun is not pulled away from a nearby star cluster by the combined gravity of the planets; rather, it formed in isolation from a local region of a molecular cloud.

So, the correct statements are 1 and 3, leading to the answer C.
