Hey Ally. You just got of science class, right? What are we going to learn?
Hey Bella, you'll learn the difference between intrusive and extrusive igneous rocks. You'll work in partners or groups, and you will have to try to identify the rocks.
That sounds kind of fun, but what is are intrusive and extrusive rocks?
Intrusive rocks are formed when magma slowly cools and is underground.
Extrusive rocks form by lava cooling quickly and is formed above ground.
Okay, I kind of get it now. Is there a way that I could somehow remember it?
Yeah, she told us that intrusive can be remembered as in for in the ground. Extrusive would be remembered as exit for leaving the ground.
Oh okay. Anyways that could help me identify them?
Yeah, if it is intrusive it would have large crystals, or they are big enough for you to see them with the naked eye. If it is extrusive then you need a tool to see them because they are too small to eye them without.
Okay, I understand what the differences are. Thank you
Your welcome Bella, but I think you might need to get to science class.I also need to get to math.
