Question

as streams flow through stone mountain, layers of sand build up. over time, the sand particles form a sedimentary rock called sandstone. what causes sandstone to change into metamorphic rock at stone mountain? sandstone is reshaped by erosion from a stream. sandstone builds up layers of sand at the mountain. sandstone experiences intense heat and pressure. sandstone has more sand particles compacted on top of it.

Explanation:

Metamorphic rocks form when existing rocks are subjected to high - heat and high - pressure conditions. Sandstone, a sedimentary rock, changes into a metamorphic rock through intense heat and pressure. Erosion reshapes rocks but doesn't turn them into metamorphic rocks. Building up sand layers or more sand particle compaction just affects sedimentary processes, not the transformation to metamorphic rock.

Answer:

Sandstone experiences intense heat and pressure.
