The BEFORE and AFTER pictures show the same layers of rock separated by millions of years. What geologic processes would most likely have caused this change?
additional sedimentation followed by convection currents
divergent plate movement followed by igneous intrusion
uplifting along a fault line followed by weathering and erosion
weathering followed by glacial erosion
The diagram shows a cross-section in which no layers have been overturned. The labels give events that occurred to form the cross-section. Move the labels to the blank boxes to show the order in which they occurred. Place the first event to occur in the top box and the last event to occur in the bottom box.

Clair Patterson was an American geophysicist. In 1956 he estimated the age of the Earth at 4.55 billion years. This is very close to the accepted age today. Which method did Patterson most likely use to make this estimate?
Starting in 1922, a compound of lead was added to gasoline to improve a car’s performance. In the 1960s, Patterson showed that lead in the atmosphere had increased dramatically since it’s addition to gasoline. His work resulted in the elimination of lead from gasoline and other products. Which method Patterson most likely used to show this increase of lead in the atmosphere?
Methane (CH4) is a greenhouse gas in the atmosphere. Most methane was placed in the atmosphere by human activity. Glacial ice from Antarctica has trapped atmospheric gases for thousands of years. These ice cores can be used to determine the amount of methane present in the atmosphere over time. The graph shows the methane concentration in the atmosphere for the past 1000 years. What inference can be made from this graph?
Geologists look for patterns in rocks that can help determine the relative ages of layers and fossils. The geologic column shows fossils found in four sedimentary layers. They have not been overturned. Which two fossils have formed most recently? Click on the fossils in the diagram to show your answer.
The diagram shows a desert ecosystem with fossils in exposed rock layers nearby. Three labels in the diagram are highlighted with a box border.Move the labels below to the blank boxes to show the order in which the three organisms were alive on Earth. Put the one that existed the longest time ago FIRST.
