The Deep Time Stack: Law of Superposition Explained

Before radiometric dating, geologists cracked open the Earth's timeline using one beautifully simple principle: older rocks sink to the bottom and younger rocks pile up on top. Law of superposition explained is the...

Questions: 20 | Attempts: 13 | Last updated: Mar 3, 2026

Sample Question 1
In an undisturbed stack of rock layers, the oldest layer is always found at the very bottom.

True

False

Sample Question 2
If Layer A is above Layer B, and the ground has not been moved by an earthquake, which layer is younger?

Layer A

Layer B

They are the same age

Layer A is 100 years old

Neither layer has an age

Sample Question 3
If we see the law of superposition explained in a cliff side, which things could "disturb" the layers and make them harder to read?

Earthquakes tilting the rocks

Volcanic eruptions cutting through

Rivers washing away middle layers

Sunlight shining on the rocks

Rain falling on the top layer
