Igneous rocks is originally formed due to crystallization of molten magma, it is found underground, it has a mosaic of interlocking crystals and usually have high strength, example granite or basalt magma is generated by heating and melting of rocks with the mantle due to extreme pressures and temperatures depths between 10-100km below.
The continuous cycle of rocks within the interior of the earth and on the earth's surface is known as the rock cycle geologists have recognized three different types of rocks that constantly change from one form to another through a number of different processes one such rock is the igneous rock. Igneous rock (derived from the latin word igneus, meaning of fire, from ignis meaning fire) is formed through the cooling and solidification of magma or lavathis magma may be derived from partial melts of pre-existing rocks in either a planet's mantle or crusttypically, the melting of rocks is caused by one or more of three processes: an.

Igneous rock (derived from the latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic rock igneous rock is formed through the cooling and solidification of magma or lava igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
