Study: Geologic

The geologic record contains many kinds of evidence of Earth's past. Complete the table to 

summarize five of these kinds of evidence

• Fossils

• Planet

• Landforms

• Sedimentary Rock Layers

Most fossils form in (a)   after dead animals and plants get buried in sediments

Fossils show what kinds of (a)   lived in the past.

The kinds of living things that became fossils 

show what the (a)   was once like in the places where they are found. 

What does it mean for a species to be extinct? 

• Partying

• It is no longer living on Earth

• Go see the Grand Canyon

• Living in a cave

How to find age parts of earth:

Relative dating

• Involves comparing the positions of rocks

• Ask an alien

• Check a rock for a birth certificate

• Determines whether one part of a rock 

  formation is 

  older or younger than another

How to find age parts of earth: Absolute dating

• Use a magic 8-ball and ask

• Involves analyzing the chemical makeup of rock

• Determines 

  how old the rock is

• Flip a coin

Pick what words that correctly complete the sentences: The law of superposition is used in the process of [absolute/relative] dating

(a)  

Pick what words that correctly complete the sentences: According to the law of superposition, [older/younger] layers of rock are found on top of [older/younger] layers of rock.
