Fossils and Evolution

Using relative dating, you know that the oldest layer is

• the bottom one

• the top one

• the exact middle one

• Can´t tell

What does radioactive decay measure

• Bomb radiation

• creation of fossil compounds

• relative age

• absolute age

A cast fossil is where

• a hollow chamber is preserved that represents the shape of the fossil

• fossil has a broken bone

• fossil is replaced by other minerals

• only carbon is left over

Why are fossils important in earth science?

• help us identify a time period

• help us identify the climate of an area

• look cool

• leave clues of past events that took place

Which of the following is NOT an example of a fossil?

• a petrified dinosaur bone
• a footprint captured in mud
• a seashell found on the beach
• an insect stuck in amber

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil
