What role do faults play in the Law of Superposition?

• Faults create new types of rock.

• Faults are younger than the layers they cut through.

• Faults are the same age as the layers they cut through.

• Faults are older than the layers they cut through.

Which statement best describes the Law of Superposition?

• Each sedimentary layer of rock represents 1,000 years of Earth's age, much like the rings of a tree.

• In undisturbed layers of sedimentary rocks, the upper rock layers are older than the lower rock layers.

• In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.

• Rocks that form near volcanoes are older than surrounding rock.

Sometimes a fossil is formed as a result of the movement of an organism in soft sediment. Which of the following are two kinds of trace fossils?

• shells and bones
• tracks and burrows
• bee and beetle in amber
• petrified and mummified fossils

In 1897, a British scientist proposed that Earth was between 20 and 400 million years old. Based on radiometric dating, scientists now propose a different age for Earth. Based on the most current radiometric dating data, about how old is Earth?

• 40 billion years old
• 20 billion years old
• 4.6 billion years old
• 4.6 million years old

• Dead organisms are quickly buried for millions of years.
• Animals get trapped.
• All of the above
