Question

a non-foliated metamorphic rock (such as marble or hornfels) that was formed near an upper-crustal magma body was formed by the process of contact metamorphism igneous metamorphism regional metamorphism magma metamorphism compressional metamorphism question 9 (0.83 points) the primary, underlying cause of virtually all metamorphic processes is global warming increased solar radiation metamorphic decay mantle fluid dynamics plate tectonics

Explanation:

For the first question: Contact metamorphism occurs when rocks are heated by a nearby magma body, forming non-foliated rocks like marble and hornfels, which matches the description. The other options are not valid; "igneous metamorphism" and "magma metamorphism" are not standard terms, regional metamorphism forms foliated rocks from large-scale pressure/heat, and compressional metamorphism is tied to tectonic pressure, not magma proximity.
For the second question: Plate tectonics drives the changes in temperature, pressure, and fluid flow that cause all major metamorphic processes. The other options are incorrect; global warming and increased solar radiation are surface processes, metamorphic decay is not a recognized term, and mantle fluid dynamics are a subset of processes driven by plate tectonics.

Answer:

1. contact metamorphism
2. plate tectonics
