11. how are metamorphic rocks formed? 12. describe how weathering, erosion, and deposition all impact the rock cycle. 13. which type of rock contains fossils? why would you expect to find fossils in that type of rock?
Answer
Brief Explanations:
- Metamorphic rocks form when existing rocks (igneous, sedimentary, or other metamorphic) are subjected to high - pressure, high - temperature, or chemically active fluids, causing physical and chemical changes.
- Weathering breaks rocks into smaller pieces. Erosion transports these pieces away. Deposition occurs when the transported materials settle. These processes contribute to the formation of sedimentary rocks and the recycling of rock materials in the rock cycle.
- Sedimentary rocks contain fossils. Fossils are preserved in sedimentary rocks because these rocks form from the accumulation and compaction of sediments, which can bury and preserve organic remains over time.
Answer:
- Existing rocks change under high - pressure, high - temperature, or chemically active fluids.
- Weathering breaks rocks, erosion transports pieces, deposition settles them, contributing to sedimentary rock formation and rock - cycle recycling.
- Sedimentary rocks; because they form from sediment accumulation that can bury and preserve organic remains.
