Hello dear readers! Have you ever wondered why or how volcanoes are made? Well, you're in luck. Because this animation, will inform you about inside our earth. I also found out that, the deeper you go inside the earth, the hotter it gets! I also found that, the center of the earth, is hotter than the sun! And, it's even bigger than Mars! AMAZING. I was shocked when I had discovered this. Please post a comment, and tell me one thing that you didn't know about volcanoes before!
