magmatic rocks are igneous rocks they form by magma nd magma is form by melting of rocks because several km deep the subsurface temperature is very high which melts the rock(metamorphic rock).as magma rises towards the surface the temperature towards surface gradually decreases. magma slowly cools and intrusive igneous rocks are formed nd if magma comes on surface called lava here rapidly cooling is caused nd extrusive magmatic rocks are formed
