We are currently in the Cenozoic

Which of the following is NOT an aspect of stratigraphy?

Modern evidence of continental drift includes

Tectonics produce topography, erosion removes it

Which TWO phenomena are NOT related to plate tectonics?

Absolute dating indicates relationships, relative dating indicates specific ages

Which one is NOT a type of fault?

Complete the list: Cambrian, Ordivician, Silurian....

The earliest evidence of life is around 8 million years old

Biochemical cycle components are...

Absolute dating CAN'T be influenced by external factors

¹⁶O is heavier than ¹⁸O and is therefore harder to evaporate

Which one of these is NOT a form of plate tectonics?

The first person to propose the theory of continental drift was....?

Oceanic crust is lighter than continental crust and will therefore not subduct

Which TWO factors can influence short-term climate?

The main cause of plate tectonics is ocean floor spreading

Continental drift was accepted in 1912 when it was first proposed

Sea level was 125 m lower during the last Ice Age

If atoms of an element have a half life of 22 KY, and 12.5% of the parent material remains, how old is the element?

Milankovitch cycles include...

^87/86 Sr ratios tell us about weathering rates of the crust and mantle

Radioactive decay is always linear

The Hadean and Archaean are time periods known as Eras

What are the reasons for bias in paleontology?

Carbon dating can be used for dating back millions of years

If the age of an element is measured at 5 KY, with a half life of 1 KY, how much parent material is left?

Weathering breaks material down, erosion moves it

Mineral deposits are infinite resources

Which unstable isotopes were used to prove the existence of sea floor spreading?
