We made our third layer of sedimentary rock today, shale. Shale is formed in slow moving water from the smallest particles of eroded materials, silt and clay. To top off our layer we added a leaf imprint to represent a fossil.
In your journals you started a conceptual model of the layers in the basin.
The eroded materials that make the shale are the smallest particle sizes and as such have the tiniest spaces between the grains of sand.
