Unearthing the Planet’s History

About 2 billion years ago, the oceans were green, the land red and rocky, and only 1 percent of Earth’s atmosphere was oxygen. How did the planet become what it is today? UNC geochemist Xiao-Ming Liu collects samples of soil, rocks, and water from places like Hawaii to find the answer.
