Question

Question 1

The law of superposition states that strata buried lower in the ground are younger than strata located higher up.

Question 2

Luminescence dating can be used to date pottery that has been fired.

Question 3

Carbon 14 is not an appropriate method for dating fossils from the early stages of primate or human evolution, as these events took place millions of years ago.

Question 4

Relative dating methods can provide an actual numerical age for an object or a stratigraphic layer.

Question 5

Dendrochronology is an absolute dating technique based on the fracturing of obsidian rock in the construction of stone tools.

Question 6

Human burning of fossil fuels and nuclear weapons testing have altered global radiocarbon levels.

Question 7

Inorganic material such as rocks is required for radiocarbon (Carbon 14) dating.

Question 8

Paleomagnetic dating can be used to date sediment samples ranging from several hundred thousand to millions of years old.

Question 9

Potassium-argon dating requires a sample of organic material such as bone or shell.

Question 10

Geologists have used Potassium-Argon (radiopotassium) dating to date rocks as old as 4 billion years old.

Question 11

Why is it useful to researchers to have a range of dating techniques available? Which of the dating techniques described in the text and websites are most useful for the study of human evolution, and why?

Explanation / Answer

1.The answer is false
It states that the strata buried lower are older than the ones present above it.

2.The answer is true
This is normally used for the materials in which the radiocarbon dating is not at all available, like the sediments. Most common for the ceramic wares likes potery.

3.The answer is true
Carbon 14 is unstable and undergoes radioactive decay. So the measured age changes

4.The answer is false
Relative dating will not provide the actual numerical dates for rocks, but it will give whether they are older or younger.
