Video: "Earth 100 Million Years From Now"

Video: "plate tectonics animation"

Video: "Layers of the Earth"

Here we have a video about the layers of the Earth. The problem is measures are expressed in miles (not kilometers) and in º Fahrenheit (not Celsius). Anyway is pretty funny and educative. Enjoy it, thinking in the contents of the Unit 2 of your book.
