Where do rock and mineral fragments come from?

Answer 1

Rock and mineral fragments, known as sediments, originate from the weathering and erosion of pre-existing rocks. This process breaks down larger rocks into smaller particles through mechanical and chemical means, often aided by natural forces like wind, water, and ice. These fragments can accumulate in various environments, such as riverbeds, beaches, and deserts, and can eventually cement together to form sedimentary rock. Additionally, volcanic activity can also produce mineral fragments through explosive eruptions.
