What is igneous rock

Answers:
Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).
One of the many way's it can be formed-

1.When a Earthquake is in its full form,if one of the heavier tectonic plates falls under the lighter plate,the heavier one will melt and will become into lava or magma.After this procedure there will be a little crack in between the plates so molten lava will rush out from the pressure.If the plate is under the sea,then solidification will take place and igneous rock will be fromed.
