select all the correct answers.\nthe image shows a sandstone formation with visible bands of different colors. what do the bands indicate about how this sedimentary rock was formed? choose two answers.\n\nthe rock was made from more than one type of material.\nwater was absent during the compaction and cementation process.\nsediments and other matter were deposited in layers before lithification.\nthe rock was stretched horizontally by the pressure from surrounding rocks.\nlayers of hot liquids in the rock cooled and solidified at different temperatures.
Answer
Brief Explanations:
- Different colored bands in sandstone mean the sediment came from distinct materials (e.g., different mineral compositions or organic content) deposited at different times.
- The layered banded structure is a key feature of sedimentary rocks, formed when sediments accumulate in horizontal layers over time, which then lithify into rock.
- Water is critical for compaction/cementation of sedimentary rocks, so the second option is incorrect. Horizontal stretching is a metamorphic/tectonic process, not related to the original formation of the bands, making the fourth option incorrect. Cooling of hot liquids describes igneous rock formation, not sedimentary, so the fifth option is incorrect.
Answer:
- The rock was made from more than one type of material.
- Sediments and other matter were deposited in layers before lithification.
