Question

what best describes the rock cycle? a. a one - time process b. a cycle that only forms igneous rock c. a continuous process that changes rocks over time d. a process caused only by volcanoes which two factors cause metamorphic rocks to form? a. water and wind b. compaction and cementation c. heat and pressure d. magma and lava

Explanation:

For the first question: The rock cycle is a recurring, ongoing process where igneous, sedimentary, and metamorphic rocks transform into one another over geological time, eliminating the one-time, single-rock-type, and volcano-only options.
For the second question: Metamorphic rocks form when existing rocks are altered by intense heat and pressure deep within the Earth; water/wind cause erosion, compaction/cementation form sedimentary rocks, and magma/lava form igneous rocks.

Answer:

1. C. A continuous process that changes rocks over time
2. C. Heat and pressure
