Using one to two sentences, explain how the movement of tectonic plates helps turn sedimentary rocks into metamorphic rocks.

Answer 1

The movement of tectonic plates subjects sedimentary rocks to high pressure and temperature conditions, causing them to undergo recrystallization and eventually transform into metamorphic rocks.

Answer 2

In one to two sentences, identify and describe the processes that must happen for sand to eventually become metamorphic rock.

Answer 3

The sand must first undergo compaction and cementation to form sedimentary rock, and then be subjected to intense heat and pressure during tectonic activity, causing the minerals within the rock to recrystallize and transform it into metamorphic rock.
