Front

What is relative age dating?

Back

A method used to determine the age of one event in comparison with other events.

Front

What does the letter 'F' represent in geological terms?

Back

Fault.

Front

What does the Principle of Cross-Cutting Relationships state?

Back

An igneous intrusion is always younger than the layers it cuts across.

Front

In which type of rock are fossils typically found?

Back

Sedimentary rock.

What is an intrusion in geology?

Back

An igneous rock that has formed from magma that has cooled and solidified within pre-existing rock.

Front

Define unconformity in geology.

Back

A surface of contact between two groups of unconformable strata.

Front

What is the significance of fossils in sedimentary rock?

Back

Fossils provide evidence of past life and can help date the rock layers.

Front

What is the difference between a fault and an intrusion?

Back

A fault is a fracture in the Earth's crust where blocks of land have moved, while an intrusion is magma that has cooled and solidified within existing rock.
