The term which names a metamorphic change in rocks over a wide area from tectonic forces in Earth's crust and mantle is: B. regional metamorphism

A rock refers to a solid naturally occurring landform that comprises minerals.

Generally, there are three (3) main types of rocks and these include;

  • Sedimentary rock.
  • Igneous rock.
  • Metamorphic rock.

Some of the natural phenomenon that influences rock cycle include the following;

I. Weathering.

II. Erosion.

III. Plate tectonic activity (force).

When a rock experiences a metamorphic change over a wide area due to the actions of tectonic forces acting on Earth's crust and mantle, it is generally referred to as regional metamorphism.

Some of the examples of regionally metamorphized rocks are: slate, schist, and gneiss.

In conclusion, regional metamorphism typically occurs over a wide (broad) area as a result of tectonic forces acting on Earth's crust and mantle.
