What If Earth Changed Completely? Ice Melt, Volcanoes and a Second Moon
What would happen if Antarctica’s ice suddenly melted, the oceans drained, or Yellowstone erupted tomorrow? Explore hypothetical Earth transformations, from a water-covered planet to a world without humans.
Discover how long traces of humanity might survive after we vanished, what a second moon could mean for Earth, and what might happen if Earth became a moon of Saturn. Plus, explore the hypothetical question: what if Earth were flat?
