5, 4, 3, 2, 1
1, 2, 3, 5, 4
2, 3, 4, 5, 1
1, 2, 3, 4, 5
According to the law of superposition, the oldest fossils are found?
In the middle of the rock layers
Somewhat near the surface
Near the bottom of the rock layers
At the top of the rock layers
Which fossil is relatively the oldest?
Gastropod
Ammonite
Crinoid
Trilobite
Analyze the seashell found in the white layer. Which statement is true of the rock layer that contains this fossil?
It could also contain a fossil from the bottom layer.
It is older than the layers above it.
It is older than the layers below it.
It is younger than the layers above it.
In order to qualify as a fossil, an object must be
Several thousand years old
Over a decade old
cool
Over a century old
Paleontologists consider fossils as
Evidence of ancient death
Evidence of ancient life
Order the events of how a fossil is made
Step 3
An animal dies and is buried quickly
Step 4
Decomposers break down the animals skin, muscles, and organ cells
Step 2
Over time more layers develop over the sediment.
Step 1
Layers of sediments cause pressure to squeeze water out of the bones
Plants leave fossil remains known as
Impressions
Depressions
Traces
In this rock layer diagram there are two strange formations. The first is an earthquake fault at E. The second isan intrusion at D. Which occurred first? How do you know?
Intrusion D occurred first because the instrusion has been moved after by the earthqauke that created the fault.
The fault E happened first because it is an earthquake that causes disruptions and such immense shakings.
