• It reveals information about past life and environments

• It tells us how to find gold and minerals

• It explains the formation of the moon

How do you think geologists use rock layers and fossils to learn about the past?

Multiple Choice

Which of the following best describes what a fossil is?

• A living organism found in sedimentary rock

• A preserved remain or trace of a past organism

• A type of mineral found in rocks

• A layer of volcanic ash

Multiple Choice

How do sedimentary rock layers help geologists learn about Earth's history?

• They show the exact age of the Earth

• They contain fossils and represent different time periods

• They are always the same color

• They only form in deserts

Multiple Choice

Explain how relative dating helps scientists determine the sequence of events in Earth's history.

• Relative dating uses fossil records to determine the exact age of rocks.
• Relative dating relies solely on radiometric dating techniques.
• Relative dating can only be applied to igneous rocks and not sedimentary layers.
• Relative dating determines the sequence of events in Earth's history by analyzing rock layers and their relationships.

Fill in the Blank

According to the Law of Superposition, in undisturbed rock layers, the oldest rocks are found at the ___.

Multiple Select

Based on the diagrams, which of the following statements are correct about how rock layers and fossils are deposited over time?

• The youngest fossils are always at the bottom

• Rock layers are deposited from the bottom up

• Older fossils are found in deeper layers

• Fossils are only found in the top layer

Multiple Choice

Describe the three main steps geologists use when applying relative dating to determine the ages of fossils and rock layers.

• The three main steps are observing stratigraphy, applying the principle of superposition, and correlating rock layers and fossils.
• Analyzing the chemical composition of fossils
• Using radiometric dating techniques
• Measuring the temperature of the rocks

Multiple Choice

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers
• Near the bottom of the rock layers
• In the middle of the rock layers
• Somewhat near the surface

Multiple Choice

What does each colorful band of rock in the Grand Canyon represent?

• A different era in Earth's history

• A different type of mineral

• A different climate zone

• A different river path

Multiple Choice

Which of the following statements about the Law of Superposition is correct?

• It determines the relative age of rock layers and fossils.

• It determines the exact numerical age of fossils.

• It only applies to marine fossils.

• It is used to identify the chemical composition of rocks.

Multiple Choice

Explain how fossils and rock layers act as a 'history book' for Earth.

• Fossils are only found in sedimentary rocks.
• Fossils and rock layers serve as a historical record of Earth's biological and geological changes over time.
• Rock layers do not change over time.
• Fossils are created by volcanic activity.
