Layers in the Railway Cutting
A drawing the class made of the rock face beside the railway, from top to bottom.
FROM THE TOP DOWN
Top layer: soil with modern roots
Next: sandstone with ripple marks
Next: grey mudstone with sea shells
Next: coal with fern fossils
Bottom: hard rock with no fossils at all
The layers lie flat and one on top of the other.
1. What does the mudstone with sea shells suggest?
2. What is in the coal layer?
3. What is in the layer with sea shells?
4. Which layer is oldest, and how do you know?
2.Sea shells sit below a soil layer with modern roots. What changed?
A.The place went from sea to dry land over a long time
B.The roots grew into the sea
C.Nothing changed
3.What would you expect below the lowest layer in the cutting?
A.Rock older still, formed before everything above it
B.Modern soil
C.The same soil as the top
4.Why does the ORDER of the layers matter as evidence?
A.It shows which conditions came first and which came later
B.It makes the drawing neat
C.Order is not evidence
5.Ripple marks are preserved in a sandstone layer. What do they suggest?
A.The rock melted
B.Somebody drew them
C.Water or wind moved sand here when the layer formed
6.The bottom layer has no fossils at all. What does that suggest?
A.Fossils were removed
B.It is the youngest
C.It formed before those organisms lived here, or in conditions that preserved nothing
7.A layer holds sea shells. What does that suggest about this place?
A.The rock is made of shells only
B.Somebody dropped shells there
C.It was once under the sea
