The four columns in this diagram represent fossil-bearing sedimentary rock layers at four different sites. The sedimentary layers are continuous except at the zigzag lines, which represent unconformities. Compare the sites, determine the relative ages of the fossils, and then identify the FALSE statement.Click to view larger image.

The boundary surface between two stratigraphic formations is called a: 

The earthquake that occurred when the asteroid/comet hit earth and wiped out the dinosaurs was a magnitude 12.

If you equate all Earth history to one calendar year, the history of our species (Homo sapiens) would occupy:

In a “nonconformity” the rock layers are parallel above and below the unconformity.

The time it takes for one quarter of a group of a radioactive element’s isotopes to decay is called the “half life.”

Identify the FALSE statement. Radiometric dating:

Identify the structure that makes this pattern of rock layers on the ground surface: parallel stripes, showing bilateral symmetry across a mid-line (hinge), with rock getting older as you move outward from the hinge. 

In this study radiation damage in zircon crystals are examined in order to:
