Like an exceptional lifeboat drifting through the universe, our Earth is a strange and wonderful place. From its majestic Himalayan mountains to the black fathoms of the Mariana Trench, from the gurgling geysers of Yellowstone to the empty cold heart of Antarctica, it’s full of odd and captivating places. Each varying ecosystem is driven by many of the same geologic forces and weather principles that affect every corner of the planet. But what do you really know about the basis facts of Earth science?
