• Measuring the age of a tree

• Measuring the age of a house

• Measuring the age of the everglades

What method does radiometric dating use?

• Special tools to measure how what percent of a rock is Nitrogen

• The change of color due to radiation over millions of years

• The rate of decay of specific elements

• How radioactive a sample of rock is

If you find a marine fossil in a desert, what information can you gather from this?

• A hurricane carried the marine animal and dropped it in the desert

• A bird carried the marine animal from the ocean and dropped it in the desert a long time ago

• The desert was actually an ocean a long time ago

• The marine animal walked from the ocean to the desert where it died due to the heat

When bending or breaking occur, what does this do to the sedimentary layers?

• They stay in their general order of age, but the shape changes

• Bending and breaking completely alter the order of all layers

• They stay exactly the same because the rock layers are too thick to be affected

• Bending and breaking only occurs near the core

Which is NOT correct about the picture?

• 1 is the youngest layer

• 5 is younger than 6 but older than 7

• 7 is younger than 2 but older than 4

• 7 was formed during layer 3

Fossils can tell us about the ancient climates around the world. How does climate change over time?

• Climate change is usually sudden, with warmer areas suddenly become filled with ice

• Climates do not change

• Climates change quickly due to volcanoes heating the Earth when they erupt

• One way climates change is due to tectonic plates moving over time, slowly changing the climate of the land as it moves

What is the Law of Superposition?

• In undisturbed sedimentary rock, the oldest layers are on the bottom while the youngest layers are on the top

• In undisturbed sedimentary rock, the oldest layers are on the top while the youngest layers are on the bottom

• In disturbed sedimentary rock, the oldest layers are on the top while the youngest layers are on the bottom

• In disturbed sedimentary rock, the oldest layers are on the top while the youngest layers are on the bottom

Why is the Law of Superposition a law instead of a theory?

• It is an explanation that cannot change over time

• It is an explanation that can change with new evidence

• It is an observable fact that cannot change over time

• It is an observable fact that can change with new evidence

What is NOT a way that scientists can gather information about layers of rock?

• Fossils can show what the climate was like when the layer formed

• If fossils are not present in the immediate area, then the rock layer is older than life on Earth

• Scientists can use the Law of Superposition to relatively date the rock layers

• Layers of ash are easily identifiable and can be used as chronological "book marks"

Which (2) are NOT true about absolute dating?

• Absolute dating can give an exact age (Example: 150,792 years)

• Absolute dating can provide a range of how old something is (Example: 500,000 - 500,500 years)

• Absolute dating uses the decay of certain elements in rock to calculate the age

• Absolute dating is used for things like trees or other objects that are old but not super old
