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.

Answer 1

C.) Sandstone experiences intense heat and pressure.

Step-by-step explanation:

I jus got it right on edge.

Answer 2

The reason that causes the sandstone to turn into a metamorphic rock is that it experiences extreme heat and pressure.

Step-by-step explanation:

• When the process of sedimentation occurs due to the accumulation of sand for a "long period of time", the layers that were once at the top get buried deep under the overlaying layers of sand.

• This initially results in the sedimentary rocks formation at the bottom of this accumulation.

• Over time, the sedimentary rock at the bottom is subjected to extreme pressure and heat from above.

• The action of extreme pressure and heat on the sedimentary rock converts it into a metamorphic rock.
