Answer:
The correct answer in order is: large cloud of gas and dust > contraction of solar nebula > condensation of solid particles > accretion of planetesimals > clearing the solar nebula.
Explanation:
The cloud of gas and dust is the “solar nebula”, made by mostly hydrogen and helium; next the contraction occurs when the cloud of gas and dust starts collapsing under its own gravity and compresses in the center. Then the solid particles are gas condensed into tiny dusts grains, these grains stick to each other forming larger particles, which forms the accretion of planetesimals. These larger particles grow and accumulate creating larger planetesimals until, after a billion years of clearing the nebula, we end up with planets.
