Question

question 1 (0.87 points)
what type(s) of rock can undergo metamorphism?
○ igneous only
○ sedimentary and metamorphic
○ igneous and metamorphic
○ metamorphic only
○ sedimentary only
○ all types (igneous, sedimentary, and metamorphic)
○ only igneous and sedimentary

question 2 (0.83 points)
most regional metamorphic processes take place
○ quickly, due to meteorite impacts and tsunamis
○ slowly, near the surface of the earth
○ slowly, below the surface of the earth
○ quickly, near the surface of the earth
○ quickly, below the surface of the earth

Explanation:

1. For Question 1: Metamorphism is the process where rocks are altered by heat, pressure, and chemical changes. Igneous, sedimentary, and existing metamorphic rocks can all be transformed when exposed to these metamorphic conditions.
2. For Question 2: Regional metamorphism is caused by large-scale tectonic forces, which occur deep below the Earth's surface. These geological forces act over long periods, so the process is slow.

Answer:

1. all types (igneous, sedimentary, and metamorphic)
2. Slowly, below the surface of the Earth
