  • Q:

    What happens to rock fragments that get buried after a long time?

    A:

    Buried rock fragments may be further subjected to processes of weathering that cause them to break down into smaller particles or soil, or they may become new rocks through the sedimentary process. The sedimentary process requires time and pressure to create new rocks from rock fragments and sediment.
