You can love the earth in Berkeley.

What it really is

Geology reads the earth's layers to find out what happened and when.

Three things to try today

  1. Find a cut hillside or road cut and count the layers.
  2. Say which one is oldest.
  3. Look for the layer that is bent or broken.

For the grown-up reading this

Berkeley has a population of about 116,768. Somewhere in that number is a kid who lights up about the earth and has never met another one.

Superposition — oldest on the bottom — is a four-year-old idea that runs the whole field.

If the kid who loves this is a girl
