Final answer:
False. The rocks in the Mississippian period are primarily sedimentary, not metamorphic.
Step-by-step explanation:
False. The rocks in the Mississippian period are primarily sedimentary, not metamorphic. Metamorphic rocks form when existing rocks are subjected to high heat and pressure, causing the minerals and textures to change. However, during the Mississippian period, which is a geologic time period in the Paleozoic era, sedimentary rocks such as limestone, shale, and sandstone were predominant. These rocks formed from the accumulation and compaction of sediments over time, rather than undergoing metamorphism.
