Cracked Globe with Moving Pieces

Earth’s outer shell is broken into huge pieces called plates. These pieces move slowly, carrying continents, and over millions of years they split one ancient supercontinent into the continents we know today.

In the picture

  1. Jigsaw-shaped crust slab: a moving piece of Earth’s outer shell
  2. Dotted trail in the ocean: the path a slab has traveled away from another
  3. Large central green landmass: the ancient supercontinent before it broke apart

Examples

  • A cracked chocolate bar whose pieces slide apart on a table.
  • Icebergs drifting away from each other in cold sea.
