When magma cools deep inside earth, igneous rockforms.
The molten material deep inside Earth is called magma. When magma cools and solidifies, it forms igneous rock.
Magma is molten meaning liquid-like so it is able to move inside earth. The tectonic plates separate the earth and magma. This explains when the plates move earthquakes and volcanoes occur. Lava is not magma by the way! lava is hardened magma and magma is molten!
Coarse-grained igneous rocks are formed when magma cools slowly deep inside the Earth. Creating big crystals in them.
Magma that cools deep below the Earth's crust forms intrusive igneous rocks such as granite, diorite, and gabbro. These rocks have a coarse-grained texture due to the slow cooling process deep underground.

magma
Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
Magma is semi-molten rock heated by the earth's core.
because of the high pressure
Magma is inside the volcano, and it becomes lava when it comes out. :)
igneous rocks When magma cools and solidifies in these spaces, Intrusive or plutonic igneous rocks are formed deep beneath the Earth's surface. Intrusive features like stocks, laccoliths, sills, and dikes are formed.
