according to the diagram, though which process will metamorpic rock and igneous rock change into sedimentary rock? A. cooling of lava B. weathering, deposition, and erosion C. cementation and compaction D. heat and pressure
B. Weathering, deposition, and erosion
thank you!
I would have chosen C but of course do not see the diagram. To become sedimentary rock the sediments must be cemented and squeezed.
To determine the correct answer, let's examine the options and the processes involved in the transformation of rocks.
A. Cooling of lava: This process refers to the solidification of molten rock, which results in the formation of igneous rock. It does not involve the formation of sedimentary rock.
B. Weathering, deposition, and erosion: These processes are key to the formation of sedimentary rock. Weathering refers to the breakdown of rocks into smaller fragments, deposition involves the settling of these fragments, and erosion involves the transportation of the sediments. These processes contribute to the formation of sedimentary rock, so this option is a possibility.
C. Cementation and compaction: These processes occur during the formation of sedimentary rock. Cementation refers to the binding of sediments by minerals, while compaction refers to the compression of sediments due to overlying pressure. Therefore, this option is a possible answer.
D. Heat and pressure: These conditions are associated with the formation of metamorphic rock. Metamorphism occurs when pre-existing rocks are subjected to high temperatures and pressures, resulting in changes in their mineralogy and texture. This process does not lead to the formation of sedimentary rock.
Based on the above analysis, the correct answer should be either B. Weathering, deposition, and erosion or C. Cementation and compaction.
