According to the rock cycle, which of the following transitions are possible? Assume an unlimited number of steps.
A. An intrusive igneous rock becomes a sedimentary rock.
B. A sedimentary rock becomes soil.
C. A metamorphic rock becomes an extrusive igneous rock.
D. All of the above are possible.
A. An intrusive igneous rock becomes a sedimentary rock.
B. A sedimentary rock becomes soil.
C. A metamorphic rock becomes an extrusive igneous rock.
D. All of the above are possible.
D. All of the above are possible.
According to the rock cycle, rocks can undergo various processes and transitions over time. Intrusive igneous rocks can be exposed through erosion, weathering, and transportation, eventually becoming sediment. Sediments can undergo lithification and become sedimentary rocks. Metamorphic rocks can be subjected to heat and pressure and transform into other metamorphic rocks, or they can melt and become magma, which can then cool and solidify to form extrusive igneous rocks. Therefore, all of the given transitions are possible within the rock cycle.
