Sedimentary rocks form in layers. Layers of sedimentary rock are found at the Earth's surface and deep underground as well. The layers that are deep underground today were at the surface when they formed long ago. These layers are the oldest and have been there the longest. The layers of rock that are on top of them are younger and were formed more recently. This is called the Law of Superposition.
Students follow directions to color the layers of ‘rock’ in a cross section of sedimentary rock. They then glue the paper to ½ of a cereal box; cut and fold where it tells you to and voila! They have a visual representation of Superposition!
