How long does it take to make a igeous rock?

Answer 1

Igneous rocks form from the solidification of molten magma or lava. This process can take anywhere from a few days to millions of years, depending on whether the magma cools slowly underground (intrusive igneous rocks) or rapidly on the Earth's surface (extrusive igneous rocks). The cooling rate affects the texture and crystal size of the rock, with slower cooling allowing for larger crystals to form.
