What's Inside the Earth?
See how the earth’s interior consists of several different layers; the outer shell broken into more than a dozen moving plates; the crust criss-crossed by cracks called faults. The end results are mountains, volcanoes, earthquakes, various types of rocks, geysers and hot springs. The earth has provided and continues to provide oil, gold, silver, copper, diamonds, rubies, emeralds, salt, iron, granite, marble and much more. (26:00) |
