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: gray 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 is in the layer with sea shells?
2. What claim does this drawing support?
3. What does the mudstone with sea shells suggest?
4. What is in the coal layer?
2.A coal layer holds fern fossils. What was here then?
A.A desert
B.An ocean floor
C.A swampy forest of plants that later formed coal
3.Ripple marks are preserved in a sandstone layer. What do they suggest?
A.Somebody drew them
B.Water or wind moved sand here when the layer formed
C.The rock melted
4.Why does the ORDER of the layers matter as evidence?
A.It shows which conditions came first and which came later
B.Order is not evidence
C.It makes the drawing neat
5.A layer holds sea shells. What does that suggest about this place?
A.It was once under the sea
B.The rock is made of shells only
C.Somebody dropped shells there
6.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
7.The bottom layer has no fossils at all. What does that suggest?
A.It formed before those organisms lived here, or in conditions that preserved nothing
B.Fossils were removed
C.It is the youngest

Questions about Reading the Layers
What does the Reading the Layers worksheet cover?
It practices using rock layers and fossils as evidence of landscape change — 7 questions for Grade 4, all on NGSS 4-ESS1-1: Use rock layers and fossils as evidence that a landscape changed. The instruction to students is “Read the drawing, then answer the questions”, and the answer key follows on the next sheet.
Which NGSS performance expectation does Reading the Layers practice?
4-ESS1-1, under Earth and Space Science for Grade 4. The published performance expectation reads: “Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.” The worksheet assesses that performance expectation rather than a paraphrase of it.
What age or grade is this worksheet for?
Reading the Layers is written for Grade 4, typically ages 9-10. It is one of the sheets on 4-ESS1-1, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.
Does Reading the Layers come with an answer key?
Yes. All 7 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.
How many different versions of Reading the Layers can I print?
25 — one per student, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.
Is Reading the Layers free to print and photocopy?
Yes. Reading the Layers, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.
Is there a lesson plan to teach 4-ESS1-1?
Yes — “Reading the Layers” is a 55-minute Grade 4 plan for 4-ESS1-1, timed section by section, with the misconceptions to expect and an exit ticket. Reading the Layers is the practice that follows it.
