The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time. For example, sedimentary rock shale becomes slate when heat and pressure are added.

1. These are the processes that form sedimentary rock.

2. This is molten rock that is ON Earth's surface. For this to happen, it has to erupt from a volcano.
Image: Lava

3. (temperature at which a solid becomes a liquid) - Rocks can also be completely melted into magma and become reincarnated as igneous rock.

4. The buildup of land by depositing sediment and soil in a new location (drop it)

5. The movement of sediments. This can be caused by water, wind, or even glaciers. Take it

6. Set of natural processes that form, change, break down, and reform rocks.

7. This is the process that forms igneous rock.

8. Rock that forms as heat and pressure cause changes to an existing rock
Image: Metamorphic Rock

9. This igneous rock forms as erupted lava cools quickly on Earth's surface. Because it cools so quickly, these rocks have very, very tiny crystals.

10. Rock that forms as Magma or Lava cools
Image: Igneous Rock

11. Rocks are classified into groups based on how they _____.

12. This igneous rock formed underground as magma cools slowly. Because it cools slowly, the crystals inside the rock grow very large.
