Organic Sedimentary Rock
Oceanic crust
Continental crust
Continental crust
Slide 13 - Drag question
Ammonites and Trilobites are important for geology. Why?
Slide 14 - Open question
Relative age
Absolute age
The age of a fossil in millions of years
The fossil is as old as the layer in which it is found
The fossil and the layer in which it is found are older than the layers that lie on top
The age is determined with the help of the rock's radioactivity
Slide 15 - Drag question
The remains of Mammoths have been found on the bottom of the North Sea. Explain how this is possible
Slide 16 - Open question
The soft parts rot away
The fish remains are buried by layers of sediment
The sedimentary layers turn into rock
The rock is moved up to the surface
The fossil is removed from the rock with a hammer and chisel
Slide 17 - Drag question
Place the items with the right crust
Continental crust
Oceanic crust
Ocean floor
Limestone
Coal
Brown coal
Basalt
Organic sedimentary rock
Volcanic rock
Relatively light rock
Relatively heavy rock
