Law of superposition review

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

What does the Law of Superposition help scientists determine?

Back

The Law of Superposition helps scientists determine the relative age of rock layers.

Front

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

Back

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

Front

What is radioactive dating used for?

Back

Radioactive dating is used to determine the absolute age of rocks.

Front

Which rock layer is relatively the oldest: H, P, L, or M?

Back

M is relatively the oldest rock layer.

Front

Which rock layer is relatively the newest: Kaibab formation, Zoraster Granite, Redwall limestone, or Unkar group?

Back

Kaibab formation is relatively the newest rock layer.

Front

What is the difference between relative age and absolute age?

Back

Relative age is the age of a rock layer compared to other layers, while absolute age is the actual age of the rock in years.

Front

What type of rock layers does the Law of Superposition apply to?

Back

The Law of Superposition applies to sedimentary rock layers.

Front

What happens to rock layers that are disturbed?

Back

If rock layers are disturbed, the Law of Superposition may not apply, making it difficult to determine their relative ages.

Front

What is an example of a sedimentary rock?

Back

An example of a sedimentary rock is sandstone.
