Earth Science Chapter 6 Lyrics

 

Fossil Eyes

 

With relative dating a geologist

can tell if an event or an object is

older or younger than another one is

So how do they achieve this mission?

 

Ôcos younger rocks lie above older rocks

itÕs  the principle of superposition

 

 

With absolute dating a geologist

can tell how many years an object has existed

radiometric dating is a common method

So how does it all relate then?

 

Ôcos fossils tell us what the world was like in the past

and here are some ways to make them...

 

An organismÕs tissue pores are filled with minerals

in permineralization.

Insects get stuck in tree sap which hardens to

an amber preservation.

And some of the best fossils are frozen and kept

in a state of refrigeration.

 

 

With the geological timescale a geologist

divides the long history of planet Earth

eons into eras and then periods

then epochs

 

And evidence of life is preserved in fossils

so here are some things to think of...

 

An organismÕs tissue pores are filled with minerals

in permineralization.

Insects get stuck in tree sap which hardens to

an amber preservation.

And some of the best are quickly frozen and kept

in a state of refrigeration.

 

An organismÕs tissue pores are filled with minerals

in permineralization.

Insects get stuck in tree sap which hardens to

an amber preservation.

And some of the best are frozen and kept

in a state of refrigeration.
