Question

question 8 of 10
what begins the process of solar system formation?
a. a nebula is spread apart by antigravity.
b. an accretion disk spins and increases in temperature.
c. gas and dust in a nebula is disturbed by an outside force.
d. gravity pulls matter in close together.

Explanation:

The solar system forms from a nebula of gas and dust. The initiating event is a disturbance (like a supernova shockwave) to this nebula, which makes gravity begin collapsing the material. Option A is incorrect as antigravity does not drive this. Option B is a later step, not the start. Option D is part of the process but requires an initial disturbance to begin acting on the concentrated material.

Answer:

C. Gas and dust in a nebula is disturbed by an outside force.
