The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.
Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly.
When it pours out on Earth's surface, magma is called lava. Yes, the same liquid rock matter that you see coming out of volcanoes.
On Earth's surface, wind and water can break rock into pieces. They can also carry rock pieces to another place. Usually, the rock pieces, called sediments, drop from the wind or water to make a layer. The layer can be buried under other layers of sediments. After a long time the sediments can be cemented together to make sedimentary rock. In this way, igneous rock can become sedimentary rock.
All rock can be heated. But where does the heat come from? Inside Earth there is heat from pressure (push your hands together very hard and feel the heat). There is heat from friction (rub your hands together and feel the heat). There is also heat from radioactive decay (the process that gives us nuclear power plants that make electricity).
So, what does the heat do to the rock? It bakes the rock.
Baked rock does not melt, but it does change. It forms crystals. If it has crystals already, it forms larger crystals. Because this rock changes, it is called metamorphic. Remember that a caterpillar changes to become a butterfly. That change is called metamorphosis. Metamorphosis can occur in rock when they are heated to 300 to 700 degrees Celsius.
When Earth's tectonic plates move around, they produce heat. When they collide, they build mountains and metamorphose (met-ah-MORE-foes) the rock.
The rock cycle continues. Mountains made of metamorphic rocks can be broken up and washed away by streams. New sediments from these mountains can make new sedimentary rock.
The rock cycle never stops.

Igneous -produced under conditions involving intense heat, as rocks of volcanic origin or rocks crystallized from molten magma.
Sedimentary- formed by the deposition of sediment, as certain rocks
Metamorphic- pertaining to or exhibiting structural change or metamorphism

a million. Ignius rocks- rocks that are created from molten lava. 2. Sedimentary rocks- rocks that are shaped via layering of sediments (bits of alternative rocks). 3. Metamorphic rocks- rocks that are replaced from one form to a different via warmth or tension. right this is how the cycle is going: Molten lava (warm liquid rock) cools to type ignius rocks. Ignius rocks are then the two weathered to type sediments, which flip into sedimentary rocks, or they are uncovered to warmth or tension and led to to get replaced, forming metamorphic rocks. If the ignius rock re-melts, it turns into lava returned and the cycle restarts. If the rock turns into sediments, that's going to become sedimentary rock that can then be metamorphosed or melted, commencing the cycle returned. If the ignius rock is metamorphosed, that new rock can the two soften into lava returned or it canbe weathered into sediment... and on and on.

Hmmm.. three majors rock types would be..
Igneous (basically lava rock)
Sedimentary (example: sandstone)
Metamorphic (example: marble)
I hope this helps : )
