Igneous rock

The igneous rocks have been formed due to the solidification of the molten material as a result of volcanic eruption when lava or magma spread on the surface of the earth.

At a depth ranging from 16 to 20 km from the surface of the Earth, the rocks are in a molten form and are known as Magma. When this magma rises and comes into contact with cooler pans, it is converted into solid form. This solidified magma is called Igneous rock.


The word Igneous is related to Ignition but, in this case, it has nothing to do with it.

Magma is found in the interior parts of the earth. It comes out occasionally in the form of volcanic eruptions. Accompanied by loud rumblings like thunder, smoke and fire, the magma gushes out of some fissures on the surface of the Earth.

"The world is a book, and those who do not travel read only a page", St. Augustine said. Here at www.travel-university.org we believe that every page must be read and explored. Travel is an avenue of learning that no text or classroom can teach. The world is a living classroom and you the student. We invite you to the www.travel-university.org library where you can read general interest and detail oriented articles.
