older v. younger- sequential order- The technique of establishing a

 

chronology of events arranged in relative sequential order.

 

Events not a specific time only before or after other events

• Chemo stratigraphy

• Relative age dating-

• Lithostratigraphy

• Numerical (absolute) age dating-

how much time has passed- ( how long ago it happened) specific ages-the technique of establishing when events occurred according to how much time has elapsed since their occurrence.

• Numerical (absolute) age dating

• Formation

• Relative age dating

• Correlation

What age dating is Nicholas Steno’s principles of superposition, original horizontality, and lateral continuity Charles Lyell’s principles of cross-cutting relationships and included fragments William Smith’s principle of biotic succession.

• Numerical (absolute) age dating

• Relative age dating

• Heliocentric

What age dating has these ways to tell -tree rings and coral growth lines counting layers of ice drilled from glaciers, counting sediment layers in ancient lakes, radiometric age dating

• how old the earth is

• How old the universe is

• Geologic time scale

• Numerical age

the first astronomical model – the Earth is the fixed center of the universe and everything revolves around it- Ptolemy is the person

• Geocentric

• Stratigraphy

• Heliocentric

• Biostratigraphy

Sun is the fixed center of the universe and the earth and other planets revolve around it – Galileo worked on this
