Question

Quizplus · Accepted Answer

Precambrian metamorphic rocks are typically found in continental interiors termed shields. These shields have been stable and have not been affected by the major tectonic events that have occurred along the margins of the continents. The rocks in these areas have been altered by heat and pressure over time, resulting in the formation of metamorphic rocks. These rocks can be exposed at the surface due to erosion and uplift.
