How do you describe core Accretion theory?

Core Accretion theory posits that planets form through the gradual accumulation of solid materials, such as dust and ice, within a protoplanetary disk surrounding a young star. As these particles collide and stick together, they create larger bodies known as planetesimals, which eventually coalesce into protoplanets. Over time, these protoplanets can attract additional gas, leading to the formation of gas giants, while terrestrial planets remain primarily rocky. This theory contrasts with the alternative model of disk instability, emphasizing a more gradual and orderly process of planetary formation.
