Question

In 1 to 2 sentences identify and describe the processes that make happen for sand to eventually become metamorphic rock

Answer 1

Sand can become metamorphic rock through a process called lithification, where sediments are compacted and cemented under pressure, followed by metamorphism, which involves the alteration of the original sedimentary rock (like sandstone) due to increased heat and pressure, leading to changes in mineralogy and texture, ultimately transforming it into a metamorphic rock such as quartzite. This transformation includes recrystallization of quartz grains and the formation of new minerals.
