What is lava?
This layer takes up less than 1% of Earth's volume.
What is the crust?
This is the hotter of the two version of liquid rock.
What is magma?
Because intrusive igneous rocks have large crystals, they have this texture.
What is coarse?
I have a glassy texture, black in color, and if you combine ten of me, I make a nether portal.
What is Obsidian?
Igneous rocks are formed by the cooling of these two things
What is Magma and Lava?

Extrusive Igneous rocks have a smooth texture because of this.

I am the gray rock that we looked at in class. I'm not salty, but it's in my name.

The size of the crystals in igneous rocks are determined by this.
What is the rate of cooling?
Igneous rocks don't solidify at this layer, because it's already solid.
What is the inner core?
This type of igneous rock cools very slowly because it is insulated by the inside of the Earth.
What is intrusive igneous rock?
Vesicles are formed by this as magma cools.
What are gas bubbles?
I am found at the bottom of the ocean floors and am very dense and hard. If I'm blocking a road, dynamite is the best way to clear me (unless I'm in Minecraft).
What is bedrock?
