What are the properties of an index fossil? How do they help determine the relative age of rock layers?

• They are widespread and existed for a short period, helping to date rock layers.

• They are rare and found only in deep ocean sediments.

• They are only found in volcanic rocks.

What is absolute age? How do you determine it?

• The age of a rock layer compared to others, determined by its position.

• The exact age of a rock or fossil, determined by radiometric dating.

• The age of a rock layer based on the fossils found within it.

• The age of a rock layer determined by its color.

What is relative age? How do you determine it?

What is the law of Superposition?

• Older layers are on top of younger layers in undisturbed rock sequences.

• Younger layers are on top of older layers in undisturbed rock sequences.

• Layers are arranged randomly in undisturbed rock sequences.

• Layers are arranged by color in undisturbed rock sequences.

Zircon crystals from Australia have been dated to approximately 4.2 billion years old. What does this suggest about their formation period relative to when the Earth formed?

• They formed after the Earth formed.

• They formed at the same time as the Earth.

• They formed before the Earth formed.

• They formed during the last ice age.

What are some discoveries that offer the strongest evidence for determining the age of the solar system?

• Fossils found on Earth.

• Meteorites and lunar rocks.

• Ocean sediments.

• Volcanic rocks.

What is the role of radiometric dating in determining the age of Earth’s materials?

• It measures the color of rocks to determine age.

• It uses the decay of radioactive isotopes to determine age.

• It compares rock layers to determine age.

• It uses the size of crystals to determine age.

How do impact craters on Earth and other planets help scientists study the early solar system?

• They provide information about volcanic activity.

• They show the effects of erosion over time.

• They offer clues about the frequency and size of past impacts.

• They indicate the presence of water in the past.

What are the 3 MAIN internal layers of the Earth?

• Crust, Mantle, Core

• Lithosphere, Asthenosphere, Mesosphere

• Inner Core, Outer Core, Crust

• Crust, Lithosphere, Core

What is the main geological feature of the asthenosphere?

• It is rigid and brittle

• It is hot and plastic-like

• It is cold and solid

• It is liquid and flowing
