View Earth from space. Orbiting 200 miles above Earth's surface, see familiar landforms: the majestic Himalayas, giant Namib desert sand dunes, jewel-like Caribbean islands. From this unique vantage point see how natural forces - volcanoes, earthquakes and hurricanes - affect our planet, and how a powerful new force - mankind, has begun to alter the face of Earth.
