Types of Rocks- Igneous
All you need to know
Ingneous rocks are made from lava that is cooled down and hardened.
How they are made
Igneous rocks are made from magma that is cooled down and hardened.
Once the magma is cooled it is called lava
How they are made
The magma reaches the earth’s surface from a volcano.
How they are made
The magma reaches the earth’s surface from a volcano.
The rock either cools inside or outside the volcano
How they are made
Rocks cool outside
Rocks cool inside
Where magmaIs kept
Igneous rocks cooled inside a volcano are called intrusive
How they are made
Rocks cool outside
Rocks cool inside
Where magmaIs kept
Igneous rocks cooled inside a volcano are called intrusive
Igneous rocks cooled outside a volcano are called extrusive
How they are made
Rocks cool outside
Rocks cool inside
Where magmaIs kept
The rocks inside the volcano have larger crystals because they cool slower.
How they are made
Intrusive IgneousRock
Large crystals
The rocks inside the volcano have larger crystals because they cool slower.
The Rocks outside the volcano have small crystals because they cool faster. Some have no crystals at all
How they are made
Extrusive igneous Rock
Little crystals
Here are some examples you need to know. You must know if they are extrusive or intrusive as well.
Examples
Here are some examples you need to know. You must know if they are extrusive or intrusive as well.
The first one is Bassalt It is extrusive It is cooled fast but has some crystals
Examples
The Next one is Obsidean It is Extrusive It has no crystals
Examples
The Next one is Obsidean It is Extrusive It has no crystals
The Next one is Pumice It is extrusive It is very light and is holy
Examples
The last is called granite It is Intrusive It has large crystals It is used for benchtops
