The process that takes place when the soft tissues of animals’ skin and organs are preserved for thousands of years is called… | Mummification |
This rock is formed when magma (lava) cools and makes crystals. | Igneous |
This rock is formed by making bigger crystals due to heat and pressure. | Metamorphic |

Rocks are broken down into small sediments is the process of… | Weathering |
If Sedimentary rock undergoes enough heat and pressure it will turn into…. | Metamorphic rock |
