Rocks Rock!

We have started our study of ROCKS!  This past week we focused on sedimentary rocks. Over time rocks and minerals are broken down into smaller pieces called sediment. Layers upon layers of sediment form sedimentary rock over hundreds of thousands of year. Most types of sedimentary rock form through 5 main steps:

  • Weathering
  • Erosion
  • Deposition
  • Compaction
  • Cementation
Ask your student how making this delicious treat helped us to learn about how sedimentary rocks form.
