which of the following would be a clue that a rock is metamorphic?
choose one option
a it has a complete fossil in it.
b it has gas bubbles.
c it is very soft.
d it has ribbon - like layers, or bands.

Explanation:

• Option A: Fossils are typically found in sedimentary rocks, not metamorphic, so A is incorrect.
• Option B: Gas bubbles are a feature of igneous rocks (like pumice), not metamorphic, so B is incorrect.
• Option C: Metamorphic rocks are often hard due to heat and pressure, so being very soft is not a clue for metamorphic, C is incorrect.
• Option D: Metamorphic rocks often show foliation (ribbon - like layers or bands) due to the rearrangement of minerals under heat and pressure, so D is a clue for a metamorphic rock.

Answer:

D. It has ribbon - like layers, or bands.
