6th Grade Science / Lesson 4 - Igneous Rocks

gneous Rocks
What will we be learning today?


  • In this lesson, we are going to learn about Igneous Rocks.

  • We will begin today's lesson, by defining Igneous Rocks


  • Igneous Rocks is formed from liquid rock, which is called magma or lava which has cooled and hardened.

  • We don't always see igneous rock because it is often hidden by a thin layer of sedimentary rock.


There are two different kinds of Igneous Rocks:


  • Intrusive Igneous Rocksis igneous rock formed when magma hardened beneath Earth's surface


AND


  • Extrusive Igneous Rocksis igneous rock formed from lava that erupted onto Earth's surface.




Let's Review What We Learned Today!


  • Igneous Rocks : magma or lava that cools and hardens

  • Two different kinds of Igneous Rocks:

  • Intrusive : magma that hardens inside the Earth's surface

  • Extrusive : lava that erupted outside the Earth's surface
