Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.
Metamorphic. By contrast, igneous rocks form from lava or magma, and sedimentary rock form from sediment. Those things are formed from previous rocks, but constitute intermediate stages: igneous and sedimentary rocks are formed indirectly from previous rocks.
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
Igneous rock was the first rock to cool on the surface.
What type of rock is formed from magma that hardens underground?
That entirely depends on what type of magma it is and under what conditions it crystallizes. If you are looking for a general rock type, the answer is igneous, but that's very general.
igneous rock
Igneous rock is formed when magma cools and becomes solid.
the type of rock formed when lava or magma cools is igneous rock..
Igneous rock, specifically extrusive or volcanic rock, is formed when lava cools and hardens. This type of rock typically has small crystals due to the rapid cooling process and examples include basalt and rhyolite.
A rock that is formed when magma cools is called a igneous rock.

An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
