- Point to a volcano in a picture and describe what is happening
The lesson
A volcano is an opening in the ground. Hot melted rock inside the Earth pushes up. That hot rock is called lava.
Try it together
Maya looks at a picture of a volcano. She sees red lava coming from the top. She knows the lava is melted rock.
Good to know
Lava is rock so hot it melted. That is why it glows and flows like a liquid.
A volcano is an opening where hot, melted lava comes out.
