NGSS.MS-LS4-4

In 1897, a British scientist proposed that Earth was between 20 and 400 million years old. Based on radiometric dating, scientists now propose a different age for Earth. Based on the most current radiometric dating data, about how old is Earth? (You may use your geologic time scale.)

• 40 billion years old
• 20 billion years old 
• 4.6 billion years old 
• 4.6 million years old

Which of these choices is an example of the way a geologist would use relative dating?

• determining the minerals that make up rocks
• placing rock layers in order of oldest to youngest
• classifying rocks as igneous, sedimentary, or metamorphic 
• using radioactive isotopes to determine the exact age of rock samples 

The law of superposition states:

• Energy isn't created or destroyed, it is simply changes form
• Each rock layer is older than the layer above it
• Fossils are only as old as the rock layer they are found in
• Intrusions are younger than the rock layer they are found in
