• Cambrian
• Geologic

Which of the following is believed to have caused the extinction of dinosaurs?

• Earthquake
• Volcanoes erupting
• Hurricanes and Typhoons
• Meteor Strike

Ice cores from Antarctica allow scientists to measure the amounts of atmospheric carbon dioxide from long ago. These samples would BEST provide evidence for:

• climate change

• continental drift

• big bang theory

• magnetic field reversal

Which of the following would most likely fossilize?

• skin
• muscles
• bone
• internal organs

An organism is UNLIKELY to be preserved as a fossil if:

• it has a shell
• it has a skeleton
• it is buried quickly after death
• it is a soft-bodied creature

Very few living things are preserved long enough after death to become fossils. This makes the large collections of fossils in museums all around the world remarkable.

Which of the following are possible processes through which an organism could be fossilized?

• Wooly mammoth trapped in ice

• Insects trapped in amber

• Mass burial of organisms from a flash flood

• All of these
