That is false. The 3 main types of rocks are igneous, sedimentary, and metamorphic
Basically, all types of Volcanoes. Molten Rock, also called Lava, and Magma are Igneous Rock. They are the rock that comes out of an erupting Volcano.
magma and sedimentary rocks. :D as well as some of the molten rock around the volcano that break off as a result of the eruption.
Coal and Sandstone are two types of sedimentary rocks.
Igneous rocks are made from magma. Magma is made of melted rocks. (When it is underground it is called magma, when it erupts on the surface of the earth, it is called lava. It's the same material though.) When magma/lava cools, it forms igneous rocks. There are many types of igneous rocks and the specific type of igneous rock can vary according to which minerals are present in the melted rock, how fast it cools, and the presence of things like water. Sedimentary rocks are made out of tiny pieces of debris. This can include tiny rocks, sand, clay, silt, and organic material. (Organic materials can vary from rotted leaves to tiny, shelled ocean creatures, or many other types of organic material.) These bits of material collect in an area, then through compaction and cementation, they stick together to form sedimentary rocks. Sedimentary rocks can also be formed when minerals are dissolved in water and are then resolidified. This type of sedimentary rock is called a chemical sedimentary rock. Oolitic limestone is a good example of this type of sedimentary rock.
All rocks are solid. Igneous, metamorphic, or sedimentary.
When magma is cooled and hardened, it is an igneous rock. That being said, there's only three left and those three are the three types of rocks. Igneous, metamorphic, and sedimentary.

There are three major types of rock: igneous (formed from the cooling and solidification of magma or lava) sedimentary (laid down as sediments) and metamorphic (changed by heat and/or pressure)

All the three existing rock families/types/classes (ie, igneous, sedimentary and metamorphic rocks) can form magma, if they become hot enough to melt and change to molten form.
Coal and Sandstone are two types of sedimentary rocks.
Rock Cycle: Igneous Rock with erosion give sediments which will compact to give Sedimentary Rock which with heat and pressure give Metamorphic Rocks which will melt with heat and pressure to give magma
The two main types of magma are mafic and felsic.
Sedimentary and igneous are types of rock (the other type is metamorphic). Sedimentary rocks are quite soft, and include chalk and limestone. Igneous rocks include granite and basalt. They are formed when magma cools.
