Geologic Time SSA Review

The oldest rock formation identified on Earth is found on the shoreline of Hudson Bay in Canada. This rock formed 4.28 billion years ago. What information does a scientist need to more accurately determine the age of a rock?

• The amount of each radioactive element present in the rock

• The percentage of each mineral that makes up the rock

• The thickness of younger rock layers that cover the rock

• The amount of weathering present on the surface of the rock

Which of these is in order from oldest to most recent?

• 4 3 2 5 1

• 3 2 1 4 5

• 1 2 3 4 5

• 3 4 1 5 2

A trace fossil includes no physical remains of the organisms body, but only a mark or structure that the fossil left behind. Which of these is not an example or a trace fossil?

• Dinosaur tracks in sediment

• An insect in amber

• A burrow in the sea floor

• Coprolite in sediment

The fossil record shows part of the history of life on Earth and can tell scientists about environmental changes over time. Which of the following statements explains what fossils of palm fronds found in Antarctica tell us about what the climate was once like?

• Palm fronds indicate an aquatic environment was once present

• Palm fronds indicate a period of drought once existed

• Palm fronds indicate a tropical climate was once present

• Palm fronds indicates Antarctica has always had a polar climate

What does each layer of rock represent?

• a period of time
• a different type of stone
• an intrusion
• a fault
