Question

1. which is the best way to complete this model of the rock cycle?a. crystallizationb. solidificationc. heat and pressured. melting17. what is a step in the process of a rock changing from sedimentary to igneous?a. crystallizationb. depositionc. erosiond. melting

Explanation:

For question 16: The arrow connects igneous rock to metamorphic rock. In the rock cycle, igneous rocks transform into metamorphic rocks when exposed to high heat and pressure, which alters their mineral structure without melting.
For question 17: To change from sedimentary to igneous rock, the sedimentary rock must first melt into magma, which then cools and solidifies into igneous rock. Melting is a required initial step in this transition.

Answer:

1. C. heat and pressure
2. D. melting
