Law of Superposition

Front

What is the Law of Superposition?

Back

The Law of Superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest layers are at the top.

Front

Where are the oldest fossils typically found according to the Law of Superposition?

Back

Oldest fossils are found near the bottom of the rock layers.

Front

Which rock layer is considered the youngest?

Back

The youngest rock layer is the one at the top.

Front

What does relative age of a rock mean?

Back

Back

The top layer of rock.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of ancient organisms.

Front

How do scientists use the Law of Superposition in geology?

Back

Scientists use the Law of Superposition to determine the relative ages of rock layers and the fossils within them.

Front

What is the significance of the Law of Superposition in understanding Earth's history?

Back

It helps scientists reconstruct the sequence of events in Earth's geological history.

Front

What is an example of a sedimentary rock?

Back

Sandstone is an example of a sedimentary rock.

Front

What is the difference between absolute age and relative age?

Back

Absolute age is the actual age of a rock or fossil, while relative age is its age compared to other rocks or fossils.
