Question

metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. again, thinking about the formation process can help. metamorphic rocks have been heated and squashed. this can lead the minerals in them to line up, creating ribbon - like layers called bands. these rocks are called foliated metamorphic rocks. you can see these bands in gneiss. if a metamorphic rock has fossils, you know it was formed from a sedimentary rock. because of the heat and pressure, the fossil will be hard to recognize and out of shape. which of the following best describes foliated metamorphic rocks? choose one option a there are easily recognizable fossils. b the rock has ribbon - like layers of bands. c they have crystals like igneous rocks. d different sized sediments can be seen.

Explanation:

To solve this, we analyze each option:

• Option A: The text says fossils in metamorphic rocks are hard to recognize and out of shape, so A is incorrect.
• Option B: The passage states "Metamorphic rocks... can lead the minerals in them to line up, creating ribbon - like layers called bands. These rocks are called foliated metamorphic rocks", so B matches the description.
• Option C: There is no mention of foliated metamorphic rocks having crystals like igneous rocks, so C is incorrect.
• Option D: The text does not relate different sized sediments to foliated metamorphic rocks, so D is incorrect.

Answer:

B. The rock has ribbon - like layers of bands.
