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.

Sandstone experiences intense heat and pressure.

Explanation:

Under the surface of the Earth, the temperature and pressure exerted on the rocks changes their composition and structure. The rock formed due to these changes are termed as metamorphic rocks. These changes in the structure of the rock transforms it to metamorphic rocks. Increase in temperature, change in pressure and increase in the level of fluidity helps in the formation of the metamorphic rocks.
