Which discovery provides the BEST evidence of the age of the solar system?

• The oldest known rocks on Earth have been dated to 3.8 billion years old.

• The Apollo 17 mission found moon rocks that have been dated to 4.5 billion years The volcanic activity that occurs on Earth’s surface has recycled all its rocks at least

• C. once since its formation.

• D. oldest-known Earth rocks.

Which technique BEST helps scientists determine the age of the solar system?

• creating computer models to predict the formation of rocks on Earth and the Moon

• using radioactive decay to calculate the ages of rocks on Earth and the Moon

• using relative dating techniques on layers of rocks on Earth

• comparing fossils found in the oldest rocks on Earth

A certain fossil (Y) is found in a layer of rock that lies between two index fossils, X and Z. Surprisingly, the older of the index fossils (Z) is found above the other fossils, suggesting that the rock layer has overturned. Which dating method is BEST to confirm the rock layer has overturned by determining the ages of these fossils?

• anatomical comparison

• gene sequencing

• radiometric analysis

• fossil depth measurement

The evidence in these rock layers BEST supports which conclusion?

• The oldest fossils in this section of rock are trilobites.

• Eurypterids are related to modern-day scorpions and crabs.

• Eurypterids were the least common type of organism in this section of rock.

• There is some overlap in the presence of brachiopods and ammonites on Earth.

• Intrusion X is older than layers Y and Z.

• Intrusion X is younger than all the layers.

• Intrusion X is older than the clam and broadleaf fossils.
