What is igneous rock for kids

If not read on to find out. Granite is used for making gravestones, statues, and countertops too. Do you have a granite countertop at home? Gabbro is an interesting rock that you might like to dig around for!

You could sell it to make some pocket money! Then there are things called Plutons and these are like bodies of intrusive rock that mostly have granite in them. When intrusive rocks form huge bodies, like those found inside of mountains they are called batholiths. Igneous rocks are used in many different ways.

The stonework in many buildings and statues that you see every day is made from Igneous rocks. In ancient times Diorite was used for making vases that were then decorated. You can still see many of these amazing designs in museums. Granite is used in many modern buildings, and maybe in your kitchen, you have a granite worktop—many sculptures like using granite for making statues.

The lava cooled, and as it did this it split and formed about 40, basalt pillars, which look like humongous stepping stones that reach out into the ocean. Nature and Science. This cooling is much faster than the slow cooling that forms intrusive igneous rocks. There are many different types of extrusive igneous rocks. The type of rock you get depends on what kind of lava the rock was formed from and how fast the rock cooled.

Related: Sedimentary and Metamorphic Rocks. Many mountains are made out of igneous rocks. Also, many mountains with lots of surrounding igneous rock suggest that the mountain could also be a volcano. Basalt, granite, pumice and obsidian are examples of igneous rocks. There are over different types of igneous rocks. Here are just a few. Pumice rocks are igneous rocks which were formed when lava cooled quickly above ground. The little pockets of air can be seen in them. This rock is so light, that many pumice rocks will actually float in water.

Pumice is actually a kind of glass and not a mixture of minerals. Because this rock is so light, it is used quite often as a decorative landscape stone. Intrusive rocks are made when the magma slowly cools to form rocks under the surface. Granite is one of these.

Magma is a complex high-temperature fluid substance. Magma can get forced into adjacent rocks intrusion or plutonic , or forced out to the surface extrusion or volcanic as lava , or blown out in exposions which include rock pieces tephra. Magma is made up of atoms and molecules of melted minerals. When magma cools the atoms and molecules rearrange to form mineral grains.

Rock forms when mineral grains often crystals grow together. Granite , diorite , gabbro and basalt are a few types of igneous rock. Quartz is one of the chief minerals produced by igneous action; it is made of silica SiO 2 , the most common molecule in igneous minerals. Some examples of igneous volcanic rock are pumice , obsidian volcanic glass , and scoria and much more.
