For sand to eventually become metamorphic rock, it first undergoes lithification, where sediment is compacted and cemented over time to form sandstone. Subsequently, increased pressure and temperature exerted on the sandstone over geological timescales lead to metamorphism, altering its mineral composition and structure to form metamorphic rock.
In two sentences, identify and describe the processes that must happen for sand to eventually become metamorphic rock.

Sand can turn into rock through a two-step process. First, the sand gets pressed together and glued over time to form a rock called sandstone, and then, when it is buried deeper and heated up, it changes into a different type of rock called metamorphic rock.

Sand can become rock in two main steps. First, the sand packs together to make sandstone, and then, when it gets buried and heated, it changes into metamorphic rock.
