Question

Using one to two sentences, explain how the movement of tectonic plates helps turn sedimentary rocks into metamorphic rocks.(2 points)

Answer 1

In one to two sentences, identify and describe the processes that must happen for sand to eventually become metamorphic rock.(2 points)

Answer 2

The movement of tectonic plates causes the sedimentary rocks to be buried deep within the Earth's crust, where they are subjected to high temperatures and pressures, resulting in their transformation into metamorphic rocks. Additionally, the friction and collision between plates can induce intense shearing forces, leading to the recrystallization and reorientation of minerals within the rocks, further contributing to their metamorphism.

Answer 3

The processes that must occur for sand to eventually become metamorphic rock include deposition and sedimentation of sand particles, followed by burial and compaction, which leads to the formation of sandstone. With further burial and the application of heat and pressure, the sandstone undergoes metamorphism, resulting in the conversion of the sand grains into new recrystallized minerals and the formation of a metamorphic rock.
