  • Where were the Earthlings in the video? What other deserts do you know?
  • What makes a desert a desert? How is it the same or different from where we live? Very low rainfall and high rates of evaporation
  • Did the water in the lake they found really disappear? What happened to the water in it? The water didn't disappear; it evaporated.
  • What is evaporation? Evaporation is when water changes from a liquid to a gas called water vapor. This happens when molecules, or microscopic particles of water, separate from one another.
  • So where is the water that evaporated? In the air. Eventually those water molecules form larger droplets that fall to the Earth as rain or snow.
