An igneous rock is formed by the cooling and crystallization of molten rock. The term igneous is derived fromignius, the Latin word for fire. Scientists have divided igneous rocks into two broad categories based on where the molten rock solidified. Volcanic rocks(also called extrusive igneous rock...
Igneous rocks are created when lava cools and becomes hard. Learn how igneous rocks are formed and discover the two types of igneous rocks: intrusive and extrusive. How Igneous Rocks Are Formed We have all seen a volcano erupt on television or in a movie. They are explosive, and the lava...
They are the solid mineral materials forming part of the surface of Earth and are broadly categorized as Igneous, Sedimentary and Metamorphic Rocks. Rocks make up mountains, hills, valleys, plains and they also form river and ocean beds. Rocks play an important role in our life as many minera...

This type of rock forms when magma cools slowly deep within the Earth, allowing large crystals to grow. The slow cooling process results in rocks with a coarse-grained texture. Examples of intrusive igneous rocks include granite and diorite. These rocks are often visible at the surface of the...
Types of Igneous Rocks Updated on June 02, 2019 Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are calledextrusiverocks. By contrast,Intrusiverocks are formed from magma that cools underground.If the ...
