I think the answer is A because it is gravity that caused the planets to form and start orbiting around the nearest star which is the sun

Answer 2

Answer:

A. I and III only

Explanation:

Gravity is one of the four fundamental forces that exist in nature. The other fundamental quantities are the electromagnetic interaction force, the weak force and the strong force. In a simple way, gravity is the quantity responsible for defining the weight of a body, vertical and downward force that keeps us united to the planet. Gravity is extremely important for life and for the functioning of our planet in the solar system.

Among several moments when gravity was influential, we can mention:

• In the early stages of solar system formation, a fragment of an interstellar cloud of dust and gas collapsed and began rotating under the influence of gravity.
• Gravity caused small particles in the rotating solar nebula to stick together and form larger particles. This process repeated itself, forming larger and larger particles that eventually became planets.
