Imprints of the shells of ocean clams are often found in the rocks of the Appalachian Plateau provinces. What do these imprint fossils MOST likely indicate?

The incompleteness of the fossil record results primarily from which phenomenon?

• the frequency and irregular timing of organism speciations

• the metamorphism of most sedimentary rock by heat and pressure

• the geologically rapid cycling of crust material back into the mantle

• the rarity with which organic remains are exposed to fossil-forming conditions

A student is visiting a local limestone quarry and finds fossils of seashells. The quarry is located hundreds of miles from the ocean. The fossils BEST indicate that

• this area was once below sea level

• global temperatures changed over time

• erosion rook place after a flood

• volcanic activity affected the area

Why would a geologist use the law of superposition and index fossils to date a rock formation when radiometric dating is available?

• Calculating ages using index fossils confirms evolutionary sequences

• Radiometric dating is inaccurate when used on sedimentary rocks

• Radiometric and fossil dating are only effective on organic matter

• The law of superposition gives the most specific dating information

The half-life of a radioactive element, such as carbon-14, is the time it takes for half of the atoms of the element to decay. How many half-life periods have passed if a fossil contains 1/32 of the original amount of carbon-14?
