Relative Age Core 1

Front

What is relative age in geology?

Back

Relative age is the age of a rock or fossil in comparison to other rocks or fossils, determining which is older or younger without specifying an exact age.

Front

What does the law of superposition state?

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

Which layer is older: Layer M or Intrusion P?

Back

Layer M is older than Intrusion P.

Front

Is the statement 'Relative age of a rock is the number of years that have passed since the rock formed' true or false?

Back

False. Relative age does not provide a specific number of years.

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

In a sequence of rock layers labeled A, B, C, D, and E, which layer is the youngest?

Back

Layer A is the youngest if the layers are in order from oldest at the bottom to youngest at the top.

Front

What is an intrusion in geology?

Back

An intrusion is a body of igneous rock that forms when magma cools and solidifies beneath the Earth's surface.

Front

How can you determine the relative age of rock layers?

Back

You can determine the relative age of rock layers by examining their position, the presence of fossils, and geological features.

Front

What is the significance of fossils in determining relative age?

Back

Fossils help in determining the relative age of rock layers by providing clues about the time period in which the organisms lived.

Front

What does it mean if a rock layer is tilted?

Back

If a rock layer is tilted, it indicates that geological forces have acted on it after its formation, potentially altering its original position.
