EARTH HISTORY from your favorite science cat

What information can be gathered from ice cores?

• identifying details from Earth's history, usually related to climate
• how cold it is in Alaska
• the type of rock that existed in the future
• how fossils can be used to tell about Earth history

What does the Law of Superposition state?

• older rock layers are found below younger rock layers in undisturbed rock
• younger rocks on the bottom, older rocks on the top
• matter can not be created or destroyed in a chemical reaction
• fossils use the Law of Superposition in order to maintain discipline in fossil school

Why is carbon-14 used with fossils?

• to relatively date the fossil and estimate its age in years
• to relatively date the fossil and estimate its age using position
• to radioactively date the fossil and give its actual age in years
• to radioactively date the fossil and place its age using its position in rock layers

Why do geologists use index fossils?

• to determine the size, shape and behavior or index dinosaurs
• to identify how the tectonic plates around fossils moved
• to carbon-14 date the rock layer that the index fossil was found in
• to estimate the age of a rock layer using their position near in index fossil

Why are ice cores studied by scientists?

• to learn about the inner workings of the mantel and core
• to learn about Earth's organisms that lived and died in the past
• to learn about Earth's climate, atmosphere and geological events
• to learn about how tectonic plates moved and change position over time
