Question

select all the arrows that represent metamorphism.

Explanation:

Metamorphism is the process where existing rocks (igneous, sedimentary, or other metamorphic rocks) are changed into metamorphic rocks due to heat, pressure, or chemically active fluids. So we need to find arrows pointing to "metamorphic rock" from other rock types (igneous rock, sedimentary rock) and the arrow representing metamorphic rock undergoing metamorphism (the curved arrow on metamorphic rock, as metamorphic rock can also be metamorphosed further).

1. Arrow from igneous rock to metamorphic rock: Igneous rock can be metamorphosed.
2. Arrow from sedimentary rock to metamorphic rock: Sedimentary rock can be metamorphosed.
3. Curved arrow on metamorphic rock: Metamorphic rock can undergo further metamorphism.

Answer:

• Arrow from igneous rock to metamorphic rock
• Arrow from sedimentary rock to metamorphic rock
• Curved arrow on metamorphic rock (self - metamorphism arrow)
