The statements which describe the processes involved in the accretion of planetesimals and protoplanets are:

II. Both involve the formation of solid particles from nebular materials.

IV. Both involve the trapping of gases and the clumping of masses of matter.

Accretion can be defined as the accumulation of coastal sediment, sand or land mass on a tectonic plate at a subduction zone over time.

Planetesimals refers to the small celestial bodies of a combination of dust, rock and gas which combines to form the planets, after the solar system begin to form.

Protoplanets can be defined as a large collection of matter within a giant cloud of gas and dust in orbit around the sun and developing into a planet. Thus, a protoplanet is a large planetary embryo in its early stages of evolution through accretion.

Basically, the processes involved in the accretion of planetesimals and protoplanets are;

  • The formation of solid particles from nebular materials.
  • The trapping of dusts, gases and the clumping of masses of matter such as rocks.
