These sedimentary rocks are progressively buried and undergo metamorphism and at high enough temperature and pressure melt to form magmas and the cycle starts. |
Use the following five processes to label every arrow on the rock cycle diagram: compaction and cementation, melting, cooling and hardening, heat and pressure, ... |
The Earth's rock cycle is an endless process that constantly transforms one type of rock into another through various natural processes. |
