Example of igneous rock

Rocks do not have a definite composition of mineral constituents. Feldspar and quartz are the most common minerals found in rocks. There are many different kinds of rocks which are grouped under three families on the basis of their mode of formation.

I love Science! I found it very interesting learning where rocks comes from. We see some form of rocks everyday and most really never think about where they are originated. This pin gives characteristics of extrusive and intrusive igneous rocks as well as a few examples of each.

Based on the formation process, there are three main types of rocks found on the Earth: Igneous, Metamorphic, and Sedimentary. Igneous rocks are formed when magma or lava (molten rock) cools and hardens.

The Organ Pipes in the Gawler Ranges are an example of columnar jointing, a geological structure where fractures in the rock form columns. ⁠ ⁠ Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts.⁠ ⁠ These rhyolite pillars were formed 1500 million years ago when volcanic eruptions produced approximately 30 000km³ of lava. The temperatures reached were exceptionally high causing a highly viscous magma.

Igneous rocks are rocks that formed from the cooling and solidification of magma or lava. Magma is molten rock that is below the surface of...

How Do You Describe an Igneous Rock? Different parameters are used to describe an igneous rock which are described in detail. Characterizing Color and Texture If you wander around a city admiring building facades, you’ll find that many facades consist of igneous rock, for such rocks tend to be very durable. If you had to describe one of these rocks to a friend, what words might you use? You would probably start by noting the rock’s colour. Overall, is the rock dark or light? More specifically…
