What is the significance of fossils in relative dating?

Back

Fossils help to establish the relative ages of rock layers and can indicate the environment in which the rock was formed.

What is an unconformity in geological terms?

Back

An unconformity is a surface that represents a gap in the geological record, indicating that sediment was not deposited for a period of time.

What is the difference between relative dating and absolute dating?

Back

Relative dating determines the order of events without providing specific ages, while absolute dating provides a numerical age for rocks or fossils.

What is the principle of original horizontality?

Back

This principle states that layers of sediment are originally deposited horizontally under the action of gravity.
